Love these videos... and the fact that a parent is so interactive with their child. You both give me hope for the future of society. Very Cool and thank you.
PVC is not a problem for air lines except in certain environments PVC gets brittle over time as the oils leave the pipe.. It will then shatter or burst at the weak point usually a fitting screwed into the pipe to accept a hose . Use at least SCH 40 or heavier. Where I live I can take a piece of 3/4 PVC that's over 5 years old and it will shatter when being cut with a PVC cutter unless you use a saw. If it's starting to look dull and faded it's getting old. I have a friend who has sch 40 PVC in his shop for over 20 years... NO PROBLEM. He painted it and it's still working and he does bodywork. But just be aware.
Somehow her videos popped up after searching how to weld. I have a daughter slightly older that hannah in these videos. Good job to mom and dad for raising a smart one 👏👍
because unfortunatly the macho shows like kindigit garage and the gas monkey doesnt show us how to do this stuff we have to reduce ourselves to learning from a 14 year old girl. lol. im confident with my manhood though, my wife just walked by my office and i proudly said hey honey, look at whos teaching me to make a decident drier for my compresser. lol. true story.
Nice job! I have a long zig zag of copper pipe with drain valves after the compressor that gets rid of most of the moisture but I still want the air drier for plasma cutting and HVLP spraying. Your idea is just what I needed to keep from spending more time emptying the desiccant container than working. The one significant change I made was to use sintered bronze air mufflers for the filter instead of drilling holes in the pipe and using a screen. They are inexpensive and work well. Thanks again!
This young person has such a super cool way about her. If I have had a rough day at the office l come and watch her and feel better in no time. This girl is a winner. I am a very big fan. I just don't know what I am going to watch when she gets her bug done???
Hannah I don't why you haven't posted more videos but if you can it would be gratefully appreciated. You give a lot of people a lot of help and for that I thank you. Never let the haters stop you just delete their comments and carry on. I still want to know what happened with your bug good or bad. We all learn something even from failure so carry on and love all 13 of your videos.
I'm gonna build this and put some mesh around the tube in case it explodes (even though Thor disagrees). I love your channel, Hannah! I've learned a lot from you. Thanks!!
For those who are concerned about Explosions ... You could make a 3/4 inch plywood frame around the outside (top, sides, NO bottom) and a 3/4 inch plywood door on hinges to open when you want to work on it or change desiccant. If it were to blow it would blow all the chips out the bottom onto the floor not causing anyone any injury (or hardly any).
@Chairman of the Board I imagine that is true. but schedule 80 PVC has a max working pressure of 340 psi - that would be a 300% over rated. I worked in the woodworking industry for 15 years starting in high school and I never saw a PVC rupture and yet it was used all over the facility. so what is your experience? have you ever seen PVC rupture carrying 100-120 psi air?
Mine just exploded this morning, wear and tear over five years of use in a machine-shop setting. It's not the values the materials are rated for but the stresses introduced every time the media is changed , I think, that caused it. Luckily no one was in that room when it happened. Going to have a sheet of plywood in front of the next one!
Wish my grandson had half you ambition young lady. Who ever is your mentor is an outstanding individual. I would say that in your not to distant future you will have many doors of opportunity open for you. Good luck.
Amazing. This just put a whole lot of smile on my face. was just here to see how a desiccant dehumidifier looks like and was pleasantly surprised to see someone probably half my age able to make one by herself (when I have no idea even what it is). Love Love love.
Very good job to the girl making it & the parent(s) to help her do it. Wish there was more families out there that could do things together like this & kids that want to learn with their hands and not electronics. Might have to make one for my air compressor & see how well it works.
Hannah, at some point in your life, we’d all love an update. Did you finish the bug? Did something happen that prevented finishing? Was UA-cam just a place you decided not to be as a young person? I still show your videos to my students at school as an encouragement, and it would be cool to have an end to the story (even if it didn’t go as planned, much of life doesn’t, and that’s a fantastic lesson for kids too).
Amazes me how some men on here are scared a young lady can teach them something, Hannah you are awesome keep up the good work, happy to see you can share your knowledge with others, keep it up you have a fan here !
Just finding this in 2023 and sad to see you haven’t posted in six years. By far one of the most entertaining how-to’s out there. Subbed anyway in hopes that you will come back!
Just saw a couple of your videos for the first time. I made a desiccant drier for my compressor with galvanized steel pipe. It isn't as snazzy as yours but it does the job. I don't want to be That Guy but it really is fairly dangerous to make this out of PVC. Ignoring anything else, PVC is far more likely to break if, say, something falls on it. Combine that with the pressure behind it and it gets ugly. You never see PVC being used for air lines in industry for good reason(s). Anyway, you definitely have what we in the industry call "madd skillz" when it comes to building things, and I think it's awesome that you build stuff. You remind me of me, though you're way ahead of me on when you started welding. I used activated alumina for my desiccant. It's cheaper and, IIRC, a bit more effective, and it doesn't break apart when it gets really wet. It doesn't have the indicator but I personally prefer that, as the cobalt in the that is nasty stuff.
You go Girrrrl!!!! Your are brilliant and will swallow this world! Let me know if you have built any air cooling dry system solar powered or any low energy consumption dry way to stay cool in a 42C humidity summer! Apparently you are at least half way through 👏👏👏👏👏👏
Fantastic video, great knowledge base. In order to minimise the safety issues with using pvc piping i would recommend using 1 or 2 pressure relief valves rated at 8 bar (100psi) (1 at the entrance and one at the exit). This is within the operating pressure according to ASTM D1785 for all your pipe tube diameters. The problem with PVC and in fact anything brittle is micro fracturing initiated by pressure cycling. So try to keep the pressure constant in the desiccant dryer you built and insert the pressure relief valves. Also don't use higher pressure than what is required for your project. 6-7 bar is more than enough. Again well done for the great explanation. I hope you are teaching this in school/university setting. A final word if the budget allows it its better to use metallic piping for this project it will literally be full proof for compressor use.
Great Video, love your enthusiasm! You should put a list of all the items with lengths you used in the comments on the video. Great to see a young lady doing these type of videos (I know years ago) but I have a 4 yr old daughter that I hope one day will have the same interest and knowledge that she and daddy can create some interesting, educational, valuable videos like this! Thanks!
I like working with pvc too! Here's a tip... When inserting your glued piece into its mating surface, start a 1/4 turn off center and insert it straight then give it the 1/4 turn to center. This twist helps seal the parts... Good video!
If only my 16 year old son would be so enthusiastic in my work shop I have so much to teach him and would love to see him so confident in making projects like this, however mine is just a "Pipe dream" :-(. well done you !!
Thanks Kieth Noneya. "prices". In new Zealand these prices are a dream. We pay depending on supplier 4 to 6 times what you pay . Good video even with the theatrics. I reglary watch your videos.
Great video little lady! Just do not know what else to say. You already have talents and skills that old guys (and gals) envy. You will do well and already on your way! JJ
I forgot to give you a tip when using slip-joint tools. These tools work best when used in the same way a pipe-wrench is used. Apply the top of the tool so that the open side is pointed away from the direction of travel and the bottom part of the tool open side points toward the direction of travel. This applies to adjustable wrenches as well. This permits the work to be done more easily, prevents rounding of the fastener heads and prevents breakage of the tools. When fastening bolts and nuts; always turn the nut if possible. :-)
Excellent You may older today! Congratulations The best use of teflon tape on U-Tube so far! Beautiful design! I love how you did angled the re-filling port ! Amainzing ! Well Thought ! A Genius Solution ! As you said it ! "Dirt Cheap" Otherwise you will have used ball shut off valves ! Only one observation! The violet stuff is to swell the PVC pipes1 Yes, PVC Pipes needs to be sanded down to fit each other without mayor resistance, but not loose ! --The Violet stuff swells the applied area only ! --Let parts to dry to touch. --Apply glue pipes and put parts together with a twist motion. **** NEVER put them together with a linear insertion at all. **** ¿To void running violet every were? Mask the pipes with masking tape and news paper or flyer's papers. I would had use ball shut off valves to empty and to re-fill, but that is just me ! God Job !!! From 0 to 10, I give you 20 !!!! Atentamente, Charlie
I made a dessicant dryer out of some steel box section with copper pipe running through it. It holds 1 kilogram of indicating beads. I'm looking for a way to scale it up and maybe a way to de-hydrate them. Putting them in the garage microwave works surprisingly well I've found, but the odd one gets burned. Great project. Thanks for posting.
Very nice project Hannah. I love how you explain what you're doing as you go, as it is fun and easy to follow. Thanks for sharing and keep u the good work!
Nice work, Hannah! My daughter Nika is super excited to see you working on your car. She's 8 years old and likes to work on projects too. She said "I'm a mini-version of her!" Looking forward to seeing more as you make progress and hope you are enjoying your summer! Sincerely, Tom (and Nika) Z
If you are looking to go even cheaper, the silica dessicant can be aquired at a grocery store as "Crystal" kitty litter. The more expensive stuff goes for around 12$/8lbs and has indicating beads spread throughout. I always have some on hand for making Sodium Silicate. Thanks for the idea, I needed a cheap drier for my E85 fuelling station build.
Very inspirational work, Hannah! Please give us an update on how well your Air Dryer works. With regard to PVC as a containment vessel, industrial users with which I have worked are concerned about the pulsations caused by on/off air releases causing micro-fractures in the plastic pipe which eventually cause ruptures and explosions. Just an FYI. Keep up the good work!
Schedule 80 PVC is more resistant to those micro fractures. It doubles the wall thickness. Love the idea. Trying it myself with this minor mod (Sch 80)
Extremely good vid, Hannah. the one thing I would caution you about, however, is leaving the key in your lathe's chuck. Sooner or later you will forget and leave the key in the chuck after you've tightened it on a workpiece. when you turn the lathe on, the key will either be thrown with considerable force or it will remain in the chuck and smash into the lathe ways, causing a lot of damage. Make a hanger for the key and develop the habit of always putting it there. Happy DIYing and stay safe!
My second attempt has lead me to a simple discovery. This time, I was able to properly size and seat the 3/4" inlet pipe and the 1/2" outlet pipe, but had not yet reached the step of gluing in the elbows. After staring at the 2" Tees for a bit, I considered rearranging them so the inlet and outlet stab out of the tops rather than the sides making the entire assembly resemble the letter "H". Further consideration of this lead me to find that a simple straight coupler, or not even cutting either of the inner pipes would make for a much more forgiving and simple assembly, so I will acquire the other parts I need and finish my build, then share my dryer once complete on a forum with photos and link back to this video both ways to pay my respect to Hannah for originally sharing such a great idea with us. I'm stoked and can't wait to dry some air!
@@robertmccully2792 I don't have it anymore, but made it and used it for about 6 months at 150 psi and it worked great. Just as long as you bake the silica beads when they get too moist, the PVC holds air well. I wouldn't use it in freezing conditions though, but otherwise, it's a great design.
My build of your idea is near complete, just have to wait for the clear sch. 40 to arrive in the mail. Some things I learned are as follows; 1) Definitely build each of the sides first before putting anything else together. I made the mistake of joining the 2 Tees together and building down to the Wye on the desiccant side before adding in the inner lines. Now I have to cut that back off, build the remaining 1/2" inners, then rejoin the 2" with a coupler to save the parts. 2) For those (like me) that don't have a lathe, I used a die grinder attachment on my little HF Dremel rotary tool to grind out the stops in the reducer caps. I also learned that the tapers needed to be sanded out, so I used plumber's abrasive mesh to gradually sand out the taper enough that I could work the respective pipes through, then I buffed the sanded surfaces smooth with the rotary tool's buffing pad. I think overall, this project will turn out good and function properly, so long as I don't get the PSI over 140, as that is Sch. 40 rated PSI. I'll let y'all know how things turn out for me, and THANK YOU Hannah for sharing this to your channel!!!
I think I discovered another mistake on my part, one that may be a costly learning experience, but I am coming to gain a deeper understanding of the difference between Schedule 40 and DWV PVC pipe. I believe it was Keith that questioned Hannah's choice to use a Tee and Elbow combo over use of a Wye, so I took it upon myself to blindly purchase the Wye. Now I come to find out DWV fittings aren't rated for PSI the way Schedule 40 is, if there is even a PSI rating. Further searching left me hard pressed to locate Sch 40 Wyes from Lowes or Home D. I found Sch 40 wyes on pvcfittingsonline.com for about $11, but that's much more than an elbow/tee combo from the big box stores. Also, many of my other parts are DWV (grrrrrrr). Lesson learned! Hannah, please share any insights you have regarding the difference b/c I still can't find much info about DWV aside from their obvious low pressure applications. TYIA!
Michael J, when I was designing my system, I looked for a y, but I also could not find one that was pressure rated and cheap. I decided to go with what I could easily find locally.
I found and used the Wye that was pressure rated and to be honest, I wish I used the 90° elbow. The 45° just doesn't allow for quick pouring the way a 90° would. The H layout works good and was way easier to build as no elbows were used internally. If I build another, I will be looking to use a + on the desiccant side to further simplify the design. My water trap doesn't collect any water, but I think I drilled too many holes in the 3/4" inlet pipe, but the desiccant side does collect a lot of water as I had to bake the desiccant twice already. The $15 desiccant I found in the art store for flower drying does have roughly 5-10% indicating beads, so it works the same as the all blue.
A good mod to this dryer would be to saturate fiberglass cloth with resin . Then wrap the plastic parts with a couple layers . This will add a large measure of safety in case the tubes gets damaged . I have a much simpler dryer using this idea . Not difficult to do and not very expensive .
you are doing a great job on your videos,, but I've been doing this stuff all my life and I really think your air dryer is dangerous you need to specify what pressure you are using because this will blow up eventually.please edit this video for safety reasons, but again your doing a great job and so far this is the only video that is just missing some very important info, keep up the great work you are an inspiration to other young people for sure.
Great Video, amazing tutorial. Water (moisture) in the paint is always my problem when doing an automotive painting for cars and bigbikes, perhaps I could invest on this project first before investing to a ready made one. I love doing projects, that's all, and I think this is one great project to build and try.
I really liked the how it works part of the vid. Hannah, you are correct in getting rid of the humidity to help control sand clumping and stopping up your blaster. However the real problem is that you are using sand. Some other medias don't have this problem. I usually spread the sand onto a tarp and leave in the sun to dry, then screen out the junk before using. If I am recycling the sand, I also screen out the fines into another bucket to use for finer sand. I assume that you are going to paint your VW and sand blasting cases problems here also. Fine dust buildup in crevices is common to all types of blasting and can cause the paint not to stick. If you get out your magnifying glass and closely examine the blasted surface you will see tiny grains of sand actually embedded in the metal Some say that this is silicon and will cause problems with some paints. Cure is to use sandpaper after blasting to knock these off. Now for the real problem with sand. I started to say this on one of the other videos, but I didn't. Sand dust causes silicosis. Irreversible and ultimately deadly. Google it. Some other medias don't. Blasting cabinets solve the problem by containing the dust. I assume that you are using a respirator under your hood The hood protects your eyes and skin but does nothing for your lungs. And it is hot. A solution that i like a lot better and that can also be used while welding, painting, or any time you need it, is outside positive air pressure. It involves an oil free air pump/fan, a long flexible hose fitted to your hood and set the pump some where where there is clean air. I set mine inside by the air conditioner/heater. I droop the hose down from the ceiling in the work area so it is out of my way. The positive pressure in the hood keeps the dust out, provides a cooling breeze across your head, and keeps the window from fogging. I tried to make a homemade one from 4" flex duct and a 4" fan but it didn't work too well and was cumbersome. So I bought one from ebay with a 120v tubine type fan and 100' of 3/4" light weight flex tubing and quick disconnect hood connectors. Works good but the fan is noisy in the house, so a remote switch to turn on and off is nice. About $250 10 years ago, $400 now, but you can easily spend 10 times that on better systems. I know its expensive, but worth it to my lungs and comfort. Can also be used to blow up air mattresses, boats, and beach toys quickly. Works pretty good for light dusting as well, not as good as an air line. Scuba compressor would work if you have one. This would be a good DIY project for you. You could run 1" pvc out to your work area/areas and then quick disconnect adaptors to your flex hose Google "positive pressure respirator system" Here is one similar to my cheap one www.ebay.com/bhp/supplied-air-respirator
CAUTION i made a drier like this and if you live in a cold climate when this is cold and you pressurize it it can ( mine did ) explode sharp pieces of pvc plastic
I live in the north east of the usa and in the winter it gets cold well below freezing it might not be an issue in australia it never got that cold when i was there
Anything that contains liquid water is going to weaken if that water is allowed to freeze. You'd need to empty the liquid water after each use in the winter.
That's exactly what I was worried about but when she said she was using pieces that where pressure rated thought it would be okay but then I don't know about the smaller fitting's and stuff I would not personally ever put plastic under air pressure.
Joey Brewer PVC is used under air pressure all the time. I had it in my former shop that sublet from a 20k sq ft wood working facility who ran a 25hp compressor through it and it worked fantastic. You do have to be careful not to impact it in any way while under pressure we had a fork lift get too close and it does explode when once it’s cracked. I wouldn’t call the pieces sharp but they were certainly flying everywhere. Ultimately it comes down to common sense use.
2" Schedule 40 PVC is rated to 280psi max working pressure. You just need to make sure that you have excellent glue joints. Been using this for years on a 150psi compressor with no issues. Just keep the assembly out of direct sunlight since PVC is not UV resistant.
I just seen this video while doing a little inquiry into an air dryer I'm in need of. This is a wonderful video! You a an amazing young lady! That being said I still wanted to give a word of caution that I thought right off the bat when hearing the material (pvc sch 40) that you are using for this build. I used to sell pneumatics and I want to stress you should never use anything other that pipe specifically made for compressed air if the intent is to put it under air pressure! The pressure rating you see on pvc pipe such as for waste water (the sch 40 your using) is a pressure rating when filled with water... and under water pressure. It is much different when comes to air. I've seen a few people below comment about the caution of using this in cold climates. That is very true but it's not simply due to water freezing in it... its due to the pvc becomes extremely brittle! Would only take the right vibration or something falling over into this pvc tubing and it will break violently. Even worse is that this type of pvc when it breaks doesn't just simply break in half... it splinters off and will become shrapnel! Extremely dangerous to put under air pressure. Regardless of whether it's cold or not. My word of caution.. NEVER use any tubing for compressed air unless it was specifically designed for air pressure applications.
That's a nice design on the drier ! I didn't know the drier beads could be regenerated, that saves a lot of $$$ ! I'd just add metal piping before the drier, sloped back to the compressor, to help condense water out of the air. Build a tip tools drip loop too, they work great. Make more videos :)
I see a lot of comments at how dangerous this is. Well I worked for years in a machine shop where all the air lines were pvc. Sometimes they would break, but never exploded. They just cracked and bled off air. I also have pvc lines in my shop for yesrs. Never had an issue. Perfectly safe.
you explain everything very clearly, normally the "pizzazz" moments are distracting when people are doing DIY vids on youtube, but yours seemed well timed and gave me a second to analyze, letting me take it in so i could follow. keep up the videos!
Did miss a couple pieces like the 2" to 1.5" inside thread for the 1.5" cap can go inside I think... and the 3/4 to 1/2 adapter needs to have a 1/2 inside thread?

Very useful video. Ignore the trolls. We know Sch 40 isnt supposed to be used for compressed air, we also know we shouldnt drive fast, but we do it because we can !
Great build, I think I'll make one myself. Cool that a tuber wrote out your list of parts. Zero offense here but when using Teflon tape you should roll it on the direction that the threads are being turned in. Three wraps in my experience is sufficient for air or water plumbing applications. If it's rolled on opposite of the rotation it has a tendency to unravel, wad up and not seal as well. It also looks professional when you're done. Looks like you could use a set of V-blocks for your drill press as well (for drilling round materials). HF carries cheap ones or you can make a set out of some hard wood. Lastly, if you're concerned in the future with laying out holes for perforating pipe for a certain percentage of flow, a good way to scribe or mark the divisions you've made is to lay a piece of angle on the side of the pipe. This serves as a cheap self centering straight edge. You could also use a height gauge. There are a million ways to do anything. Just a few tips that work for me.
monkfry, I think you have your Teflon tape comment backwards. If you have a clockwise thread, you tape in a counterclockwise fashion so that your Teflon doesn't back itself off the threads. This way as you tighten the fitting it wants to tighten the tape and not back off.
Yes he worded it wrong,but He was cottect in noticing that she wrapped it in the direction that would possibly ball it up as it was tightened.His thinking was right..,his wording was off.
WOW BEAUTIFUL!! An intelligent very impressive! Keep it up am learn chemistry an practical engineering I promise it will help you out in future! You can use a 35% salt solution as a desiccant it works very well
Love these videos... and the fact that a parent is so interactive with their child. You both give me hope for the future of society. Very Cool and thank you.
Impressive, great job, as a father with 4 daughters that all are just like you, your dad should be proud.
this message is for dad ,,,sir you have done a fantastic job i tip my hat to you
Or Mom, but of course Both!
My tool room has had PVC air lines for 7 years. Look at the pressure ratings. More than you will ever see in an air system.
PVC is not a problem for air lines except in certain environments PVC gets brittle over time as the oils leave the pipe.. It will then shatter or burst at the weak point usually a fitting screwed into the pipe to accept a hose . Use at least SCH 40 or heavier. Where I live I can take a piece of 3/4 PVC that's over 5 years old and it will shatter when being cut with a PVC cutter unless you use a saw. If it's starting to look dull and faded it's getting old. I have a friend who has sch 40 PVC in his shop for over 20 years... NO PROBLEM. He painted it and it's still working and he does bodywork. But just be aware.
Schedule 40 pvc is good at room temp for 160psi. Not a good choice to save a few bucks.
A few bucks???
Somehow her videos popped up after searching how to weld. I have a daughter slightly older that hannah in these videos. Good job to mom and dad for raising a smart one 👏👍
Just another grown man with an engineering degree learning about air dryers. Don't mind me.
Tech ingredients did an amazing explanation behind them with his two systems

Nice job! I have a long zig zag of copper pipe with drain valves after the compressor that gets rid of most of the moisture but I still want the air drier for plasma cutting and HVLP spraying.

Nice work, and excellent foresight including prices for each item. Now we can see how much we're getting screwed with plumbing supplies!
So after six years of use, how has it worked out? Would you change anything if you did it again?
Hannah I don't why you haven't posted more videos but if you can it would be gratefully appreciated. You give a lot of people a lot of help and for that I thank you. Never let the haters stop you just delete their comments and carry on. I still want to know what happened with your bug good or bad. We all learn something even from failure so carry on and love all 13 of your videos.
I'm gonna build this and put some mesh around the tube in case it explodes (even though Thor disagrees). I love your channel, Hannah! I've learned a lot from you. Thanks!!
For those who are concerned about Explosions ... You could make a 3/4 inch plywood frame around the outside (top, sides, NO bottom) and a 3/4 inch plywood door on hinges to open when you want to work on it or change desiccant. If it were to blow it would blow all the chips out the bottom onto the floor not causing anyone any injury (or hardly any).
or you could just use steel pipe....or buy an engin-nerded part
I love your alls safty advice, thank you
or just check the burst ratings and discover 140psi is the standard operating pressure theyre engineered too.
@Chairman of the Board I imagine that is true. but schedule 80 PVC has a max working pressure of 340 psi - that would be a 300% over rated. I worked in the woodworking industry for 15 years starting in high school and I never saw a PVC rupture and yet it was used all over the facility. so what is your experience? have you ever seen PVC rupture carrying 100-120 psi air?
Mine just exploded this morning, wear and tear over five years of use in a machine-shop setting. It's not the values the materials are rated for but the stresses introduced every time the media is changed , I think, that caused it. Luckily no one was in that room when it happened. Going to have a sheet of plywood in front of the next one!
Hannah, when can we expected to hear/learn more from you. Good job!👍
Wish my grandson had half you ambition young lady. Who ever is your mentor is an outstanding individual. I would say that in your not to distant future you will have many doors of opportunity open for you. Good luck.
Amazing. This just put a whole lot of smile on my face. was just here to see how a desiccant dehumidifier looks like and was pleasantly surprised to see someone probably half my age able to make one by herself (when I have no idea even what it is). Love Love love.
Very good job to the girl making it & the parent(s) to help her do it. Wish there was more families out there that could do things together like this & kids that want to learn with their hands and not electronics. Might have to make one for my air compressor & see how well it works.
Finally got mine built. This girl is talented. Love when,she says FREEEEE!
Kiddo, you're a better mechanic than many of the guys and gals I worked with building airplanes! Great job!

Just saw a couple of your videos for the first time. I made a desiccant drier for my compressor with galvanized steel pipe. It isn't as snazzy as yours but it does the job. I don't want to be That Guy but it really is fairly dangerous to make this out of PVC. Ignoring anything else, PVC is far more likely to break if, say, something falls on it. Combine that with the pressure behind it and it gets ugly. You never see PVC being used for air lines in industry for good reason(s).
Anyway, you definitely have what we in the industry call "madd skillz" when it comes to building things, and I think it's awesome that you build stuff. You remind me of me, though you're way ahead of me on when you started welding.
I used activated alumina for my desiccant. It's cheaper and, IIRC, a bit more effective, and it doesn't break apart when it gets really wet. It doesn't have the indicator but I personally prefer that, as the cobalt in the that is nasty stuff.
I see sch 40 pipes for air systems in most of the commercial garages I go into.
You go Girrrrl!!!! Your are brilliant and will swallow this world!
Let me know if you have built any air cooling dry system solar powered or any low energy consumption dry way to stay cool in a 42C humidity summer!
Apparently you are at least half way through 👏👏👏👏👏👏
Fantastic video, great knowledge base. In order to minimise the safety issues with using pvc piping i would recommend using 1 or 2 pressure relief valves rated at 8 bar (100psi) (1 at the entrance and one at the exit). This is within the operating pressure according to ASTM D1785 for all your pipe tube diameters. The problem with PVC and in fact anything brittle is micro fracturing initiated by pressure cycling. So try to keep the pressure constant in the desiccant dryer you built and insert the pressure relief valves. Also don't use higher pressure than what is required for your project. 6-7 bar is more than enough. Again well done for the great explanation. I hope you are teaching this in school/university setting. A final word if the budget allows it its better to use metallic piping for this project it will literally be full proof for compressor use.
PVC handles hundreds of PSI and is an excellent and safe, as well as affordable DIY solution.
aaaaaaaand,,,,, she can also do some machining!!! god bless whomever raised you young woman
Seems like this kid going to school not for learning, but for learn teachers how thinks works. Congrats to father!
Great Video, love your enthusiasm! You should put a list of all the items with lengths you used in the comments on the video. Great to see a young lady doing these type of videos (I know years ago) but I have a 4 yr old daughter that I hope one day will have the same interest and knowledge that she and daddy can create some interesting, educational, valuable videos like this! Thanks!
I like working with pvc too! Here's a tip... When inserting your glued piece into its mating surface, start a 1/4 turn off center and insert it straight then give it the 1/4 turn to center. This twist helps seal the parts... Good video!
I wish i had a teenage kid this productive, creative, and brilliant!!! she is such a cool character
Can't wait to show my six-year-old daughter your channel keep up the good work !!!
If only my 16 year old son would be so enthusiastic in my work shop I have so much to teach him and would love to see him so confident in making projects like this, however mine is just a "Pipe dream" :-(. well done you !!
Built mine following her directions. This thing is amazing. Work perfect.
im going to build this for my sand blast cabinet. thanks for the upload!
Thanks Kieth Noneya. "prices". In new Zealand these prices are a dream. We pay depending on supplier 4 to 6 times what you pay . Good video even with the theatrics. I reglary watch your videos.
Great video little lady! Just do not know what else to say. You already have talents and skills that old guys (and gals) envy. You will do well and already on your way! JJ
I forgot to give you a tip when using slip-joint tools. These tools work best when used in the same way a pipe-wrench is used. Apply the top of the tool so that the open side is pointed away from the direction of travel and the bottom part of the tool open side points toward the direction of travel. This applies to adjustable wrenches as well. This permits the work to be done more easily, prevents rounding of the fastener heads and prevents breakage of the tools. When fastening bolts and nuts; always turn the nut if possible. :-)
Excellent
You may older today!
Congratulations
The best use of teflon tape on U-Tube so far!
Beautiful design!
I love how you did angled the re-filling port ! Amainzing ! Well Thought ! A Genius Solution !
As you said it ! "Dirt Cheap" Otherwise you will have used ball shut off valves !
Only one observation!
The violet stuff is to swell the PVC pipes1
Yes, PVC Pipes needs to be sanded down to fit each other without mayor resistance, but not loose !
--The Violet stuff swells the applied area only !
--Let parts to dry to touch.
--Apply glue pipes and put parts together with a twist motion.
**** NEVER put them together with a linear insertion at all. ****
¿To void running violet every were?
Mask the pipes with masking tape and news paper or flyer's papers.
I would had use ball shut off valves to empty and to re-fill, but that is just me !
God Job !!!
From 0 to 10, I give you 20 !!!!
Atentamente,
Charlie
I made a dessicant dryer out of some steel box section with copper pipe running through it. It holds 1 kilogram of indicating beads. I'm looking for a way to scale it up and maybe a way to de-hydrate them. Putting them in the garage microwave works surprisingly well I've found, but the odd one gets burned. Great project. Thanks for posting.
Very nice project Hannah. I love how you explain what you're doing as you go, as it is fun and easy to follow. Thanks for sharing and keep u the good work!
Nice work, Hannah! My daughter Nika is super excited to see you working on your car. She's 8 years old and likes to work on projects too. She said "I'm a mini-version of her!"
Looking forward to seeing more as you make progress and hope you are enjoying your summer!
Sincerely,
Tom (and Nika) Z
Hannah you have done a great job in making and explaining how to build an Air Dryer for your compressor. Great job :-)
If you are looking to go even cheaper, the silica dessicant can be aquired at a grocery store as "Crystal" kitty litter. The more expensive stuff goes for around 12$/8lbs and has indicating beads spread throughout.
I always have some on hand for making Sodium Silicate. Thanks for the idea, I needed a cheap drier for my E85 fuelling station build.
This and your video on slaving multiple air compressors are worth twice the price of admission! Keep on Keepin' On, Young Blood! Girl Power!
A result of great parenting... Great job dad and young lady...
Very inspirational work, Hannah! Please give us an update on how well your Air Dryer works.
With regard to PVC as a containment vessel, industrial users with which I have worked are concerned about the pulsations caused by on/off air releases causing micro-fractures in the plastic pipe which eventually cause ruptures and explosions. Just an FYI. Keep up the good work!
Schedule 80 PVC is more resistant to those micro fractures. It doubles the wall thickness. Love the idea. Trying it myself with this minor mod (Sch 80)
Extremely good vid, Hannah. the one thing I would caution you about, however, is leaving the key in your lathe's chuck. Sooner or later you will forget and leave the key in the chuck after you've tightened it on a workpiece. when you turn the lathe on, the key will either be thrown with considerable force or it will remain in the chuck and smash into the lathe ways, causing a lot of damage. Make a hanger for the key and develop the habit of always putting it there. Happy DIYing and stay safe!
GIRL POWER! Great videos. Sorry you stopped making them. Subscribed for just in case. Aloha
You just saved me from buying that same dryer to use with my sandblaster. Thank you very much 👍
My second attempt has lead me to a simple discovery. This time, I was able to properly size and seat the 3/4" inlet pipe and the 1/2" outlet pipe, but had not yet reached the step of gluing in the elbows. After staring at the 2" Tees for a bit, I considered rearranging them so the inlet and outlet stab out of the tops rather than the sides making the entire assembly resemble the letter "H". Further consideration of this lead me to find that a simple straight coupler, or not even cutting either of the inner pipes would make for a much more forgiving and simple assembly, so I will acquire the other parts I need and finish my build, then share my dryer once complete on a forum with photos and link back to this video both ways to pay my respect to Hannah for originally sharing such a great idea with us. I'm stoked and can't wait to dry some air!
lets see your air dryer completed,, does it work? Good idea on the straight in and out thoughts,,in my case there build at right angle makes sense.
@@robertmccully2792 I don't have it anymore, but made it and used it for about 6 months at 150 psi and it worked great. Just as long as you bake the silica beads when they get too moist, the PVC holds air well. I wouldn't use it in freezing conditions though, but otherwise, it's a great design.
Michael J how long did it take before silica gets to wet, do you remember?
@@robertmccully2792 depends how wet your air is. There's no way to answer that other than experience it.
Nice sandals, i like your presentation i think you are a little star in the making!!
Nicely done. This is 7 years old, what are you doing now?
My build of your idea is near complete, just have to wait for the clear sch. 40 to arrive in the mail. Some things I learned are as follows;
1) Definitely build each of the sides first before putting anything else together. I made the mistake of joining the 2 Tees together and building down to the Wye on the desiccant side before adding in the inner lines. Now I have to cut that back off, build the remaining 1/2" inners, then rejoin the 2" with a coupler to save the parts.
2) For those (like me) that don't have a lathe, I used a die grinder attachment on my little HF Dremel rotary tool to grind out the stops in the reducer caps. I also learned that the tapers needed to be sanded out, so I used plumber's abrasive mesh to gradually sand out the taper enough that I could work the respective pipes through, then I buffed the sanded surfaces smooth with the rotary tool's buffing pad.
I think overall, this project will turn out good and function properly, so long as I don't get the PSI over 140, as that is Sch. 40 rated PSI. I'll let y'all know how things turn out for me, and THANK YOU Hannah for sharing this to your channel!!!
I think I discovered another mistake on my part, one that may be a costly learning experience, but I am coming to gain a deeper understanding of the difference between Schedule 40 and DWV PVC pipe. I believe it was Keith that questioned Hannah's choice to use a Tee and Elbow combo over use of a Wye, so I took it upon myself to blindly purchase the Wye. Now I come to find out DWV fittings aren't rated for PSI the way Schedule 40 is, if there is even a PSI rating. Further searching left me hard pressed to locate Sch 40 Wyes from Lowes or Home D. I found Sch 40 wyes on pvcfittingsonline.com for about $11, but that's much more than an elbow/tee combo from the big box stores. Also, many of my other parts are DWV (grrrrrrr). Lesson learned! Hannah, please share any insights you have regarding the difference b/c I still can't find much info about DWV aside from their obvious low pressure applications. TYIA!
Michael J, when I was designing my system, I looked for a y, but I also could not find one that was pressure rated and cheap. I decided to go with what I could easily find locally.
I found and used the Wye that was pressure rated and to be honest, I wish I used the 90° elbow. The 45° just doesn't allow for quick pouring the way a 90° would. The H layout works good and was way easier to build as no elbows were used internally. If I build another, I will be looking to use a + on the desiccant side to further simplify the design. My water trap doesn't collect any water, but I think I drilled too many holes in the 3/4" inlet pipe, but the desiccant side does collect a lot of water as I had to bake the desiccant twice already. The $15 desiccant I found in the art store for flower drying does have roughly 5-10% indicating beads, so it works the same as the all blue.
I love seeing kid engineers keep up the good work hope you are at SpaceX or tesla one day. Also turn the channel locks over
Amazing job! I own a 2001 Mexican beetle, which is one of the last beetles made. I love your videos, keep it up!
Good Job Young Lady. For those of you who are afraid of PVC, this can be made from Copper with the proper fittings.
great videos. I teach a high school shop class and I will share this with my students.
I need to meet this woman
Hannah your wonderful!! Thank's for teaching an old dog a new trick.
This build started going a different direction than what I was looking to do... but you ma'am, are hilarious.
How did this little girl get so SMart ? She has helped me out several times ... Love your videos ..
A good mod to this dryer would be to saturate fiberglass cloth with resin . Then wrap the plastic parts with a couple layers . This will add a large measure of safety in case the tubes gets damaged . I have a much simpler dryer using this idea . Not difficult to do and not very expensive .
you are doing a great job on your videos,, but I've been doing this stuff all my life and I really think your air dryer is dangerous you need to specify what pressure you are using because this will blow up eventually.please edit this video for safety reasons, but again your doing a great job and so far this is the only video that is just missing some very important info, keep up the great work you are an inspiration to other young people for sure.
Thanks for sharing this. I'll hopefully get to make one someday. You seem very comfortable in front of the camera. Best wishes,
Jim
That kid is a hoot, and well informed. Enjoyed the video.
Great Video, amazing tutorial. Water (moisture) in the paint is always my problem when doing an automotive painting for cars and bigbikes, perhaps I could invest on this project first before investing to a ready made one. I love doing projects, that's all, and I think this is one great project to build and try.
Chams Hamis Just buy a motor guard filter
HANNAH U R AWESOME ,DONT ALLOW ANYONE TO DISCOURAGE U .UARE A FUTURE TESLA U HAVE NO LIMITS,DONT LET ANYONE SAY U DO .UR THE COOLEST
Clever ticking high pressure pipe bomb you made there buddy. 👍.
Nice presentation. The comments about PVC being unsafe are correct. It embrittles and the shards can be very dangerous
Nice job Hannah. You have things under control. Good day too.
AWESOME video! We may construct this DIRT CHEAP device for our brewery to dry the air powering our keg cleaner! Cheers!
Impressive!! This video gives me hope for the future. Keen it up
Keep it up kid, you'll go far with that attitude and brain!
I enjoyed your video and learned something!
I really liked the how it works part of the vid.
Hannah, you are correct in getting rid of the humidity to help control sand clumping and stopping up your blaster. However the real problem is that you are using sand. Some other medias don't have this problem.
I usually spread the sand onto a tarp and leave in the sun to dry, then screen out the junk before using. If I am recycling the sand, I also screen out the fines into another bucket to use for finer sand. I assume that you are going to paint your VW and sand blasting cases problems here also. Fine dust buildup in crevices is common to all types of blasting and can cause the paint not to stick. If you get out your magnifying glass and closely examine the blasted surface you will see tiny grains of sand actually embedded in the metal Some say that this is silicon and will cause problems with some paints. Cure is to use sandpaper after blasting to knock these off.
Now for the real problem with sand. I started to say this on one of the other videos, but I didn't. Sand dust causes silicosis. Irreversible and ultimately deadly. Google it. Some other medias don't.
Blasting cabinets solve the problem by containing the dust.
I assume that you are using a respirator under your hood The hood protects your eyes and skin but does nothing for your lungs. And it is hot. A solution that i like a lot better and that can also be used while welding, painting, or any time you need it, is outside positive air pressure. It involves an oil free air pump/fan, a long flexible hose fitted to your hood and set the pump some where where there is clean air. I set mine inside by the air conditioner/heater. I droop the hose down from the ceiling in the work area so it is out of my way. The positive pressure in the hood keeps the dust out, provides a cooling breeze across your head, and keeps the window from fogging.
I tried to make a homemade one from 4" flex duct and a 4" fan but it didn't work too well and was cumbersome. So I bought one from ebay with a 120v tubine type fan and 100' of 3/4" light weight flex tubing and quick disconnect hood connectors. Works good but the fan is noisy in the house, so a remote switch to turn on and off is nice. About $250 10 years ago, $400 now, but you can easily spend 10 times that on better systems. I know its expensive, but worth it to my lungs and comfort. Can also be used to blow up air mattresses, boats, and beach toys quickly. Works pretty good for light dusting as well, not as good as an air line. Scuba compressor would work if you have one. This would be a good DIY project for you. You could run 1" pvc out to your work area/areas and then quick disconnect adaptors to your flex hose
Google "positive pressure respirator system" Here is one similar to my cheap one
www.ebay.com/bhp/supplied-air-respirator
CAUTION i made a drier like this and if you live in a cold climate when this is cold and you pressurize it it can ( mine did ) explode sharp pieces of pvc plastic
vin rap How cold is cold? 50 degrees F, 32 degrees F, or 0 degrees F? Would just like a verification. Thanks!
I live in the north east of the usa and in the winter it gets cold well below freezing it might not be an issue in australia it never got that cold when i was there
Anything that contains liquid water is going to weaken if that water is allowed to freeze. You'd need to empty the liquid water after each use in the winter.
That's exactly what I was worried about but when she said she was using pieces that where pressure rated thought it would be okay but then I don't know about the smaller fitting's and stuff I would not personally ever put plastic under air pressure.
Joey Brewer PVC is used under air pressure all the time. I had it in my former shop that sublet from a 20k sq ft wood working facility who ran a 25hp compressor through it and it worked fantastic. You do have to be careful not to impact it in any way while under pressure we had a fork lift get too close and it does explode when once it’s cracked. I wouldn’t call the pieces sharp but they were certainly flying everywhere. Ultimately it comes down to common sense use.
2" Schedule 40 PVC is rated to 280psi max working pressure. You just need to make sure that you have excellent glue joints. Been using this for years on a 150psi compressor with no issues. Just keep the assembly out of direct sunlight since PVC is not UV resistant.
I just seen this video while doing a little inquiry into an air dryer I'm in need of. This is a wonderful video! You a an amazing young lady!
That being said I still wanted to give a word of caution that I thought right off the bat when hearing the material (pvc sch 40) that you are using for this build. I used to sell pneumatics and I want to stress you should never use anything other that pipe specifically made for compressed air if the intent is to put it under air pressure! The pressure rating you see on pvc pipe such as for waste water (the sch 40 your using) is a pressure rating when filled with water... and under water pressure. It is much different when comes to air.
I've seen a few people below comment about the caution of using this in cold climates. That is very true but it's not simply due to water freezing in it... its due to the pvc becomes extremely brittle! Would only take the right vibration or something falling over into this pvc tubing and it will break violently. Even worse is that this type of pvc when it breaks doesn't just simply break in half... it splinters off and will become shrapnel! Extremely dangerous to put under air pressure. Regardless of whether it's cold or not.
My word of caution.. NEVER use any tubing for compressed air unless it was specifically designed for air pressure applications.
You are bad ass! I work for castair in Mn , air makes the world go round n round
That's a nice design on the drier ! I didn't know the drier beads could be regenerated, that saves a lot of $$$ !
I'd just add metal piping before the drier, sloped back to the compressor, to help condense water out of the air.
Build a tip tools drip loop too, they work great. Make more videos :)
your poppa and or mama must be soooo proud of you keep it up girl!
I like your design a lot! I'm going to make one of these myself. Awesome idea!!
Our warehouse is in Jinan, it only takes less than 10 days from the time you place the order to the delivery to you.
I see a lot of comments at how dangerous this is. Well I worked for years in a machine shop where all the air lines were pvc. Sometimes they would break, but never exploded. They just cracked and bled off air. I also have pvc lines in my shop for yesrs. Never had an issue. Perfectly safe.
Omg. First video of you I've seen and you're awesome. Very articulate and informative
Very good job well thought out. good video
Surprisingly informative great job kid
you explain everything very clearly, normally the "pizzazz" moments are distracting when people are doing DIY vids on youtube, but yours seemed well timed and gave me a second to analyze, letting me take it in so i could follow. keep up the videos!
Very Very entertaining and I bet you are driving that buggy to college by now.
Love your enthusiasm and way you presented. Very well done. Your charisma makes me want to learn more! P.s Chris only lives down the road from us :-P
First off good luck on the bug rebuild. Your father/mother taught you well about doing things safely. I look forward to your next vid.

This girl has a future. No matter how goofy or brilliant she entertains. Make way humanoides!
Many clever ideas implemented in this thing. Good job.
This has to be one of the most helpful videos I've ever seen on here!!! Wow amazing great job keep t up!!!
Very useful video. Ignore the trolls. We know Sch 40 isnt supposed to be used for compressed air, we also know we shouldnt drive fast, but we do it because we can !
Great build, I think I'll make one myself. Cool that a tuber wrote out your list of parts. Zero offense here but when using Teflon tape you should roll it on the direction that the threads are being turned in. Three wraps in my experience is sufficient for air or water plumbing applications. If it's rolled on opposite of the rotation it has a tendency to unravel, wad up and not seal as well. It also looks professional when you're done. Looks like you could use a set of V-blocks for your drill press as well (for drilling round materials). HF carries cheap ones or you can make a set out of some hard wood. Lastly, if you're concerned in the future with laying out holes for perforating pipe for a certain percentage of flow, a good way to scribe or mark the divisions you've made is to lay a piece of angle on the side of the pipe. This serves as a cheap self centering straight edge. You could also use a height gauge. There are a million ways to do anything. Just a few tips that work for me.
monkfry, I think you have your Teflon tape comment backwards. If you have a clockwise thread, you tape in a counterclockwise fashion so that your Teflon doesn't back itself off the threads. This way as you tighten the fitting it wants to tighten the tape and not back off.
Yes he worded it wrong,but He was cottect in noticing that she wrapped it in the direction that would possibly ball it up as it was tightened.His thinking was right..,his wording was off.
well young lady ........... I'm impressed ........... nice job
As an EE student, I think this channel needs more multivariable calculus.
your shop skills are for real and everytime you dropped those fittings i started laughing .
Ha! Schrodinger is the best name for a cat! Maybe he'll be the only cat on earth who doesn't like sitting in boxes
WOW BEAUTIFUL!! An intelligent very impressive! Keep it up am learn chemistry an practical engineering I promise it will help you out in future! You can use a 35% salt solution as a desiccant it works very well
