How to build a Shop Air Cleaner and Paint Booth Ventilation System
Вставка
- Опубліковано 15 лют 2019
- In this video I build a Shop Air Cleaner AND Ventilation system which kills two birds with one stone by featuring an Air Cleaner and an Air Extractor in a single unit. In a nutshell, this basically means that you can use it to filter and clean all the sawdust out of the air and then quickly convert it to an air extraction unit where you can send fumes or smokey air out of your shop to the outside. The unit was designed to use 8″ ducting and four 16x20x1 size furnace filters.

As a guy with experience in ac/ heating i would suggest you think about double walled insulated duct going thru your wall. Theres a good chance of moisture gathering on the duct and dripping down inside your wall and causing mold and rotting wood. Nice cabinet work. Design was good as well. You do realize youre never going to see the rest of your house now. I made my shop so cozy i forgot what my dogs looked like. What house?
This dude is a genius, that is an awesome idea. I really like the air diverting idea, mind blowing.
love the way you narrate and describe things!
Fantastic design, thank you so much for sharing this! I’ve been wanting to make something just like this for ages, your design adds a lot of features I hadn’t considered. Subscribed, look forward to seeing more from you 🤘🏼
12 foot ceilings, awesome. I like this idea and have my old furnace blower that I intend to do exactly this, thanks for sharing this idea. BTW I have a very similar Garage heater and it's awesome!
Well done! Also nice to see someone that still knows how to use a Radial Arm Saw.
Well done, Tommy. That is professional looking. I look forward to more videos.
Thank you!
Great video. Exactly the direction I need. Thanks!
Thanks! Glad it helped!
Very nice. When thinking about to build an air cleaner and starting to gravitate towards using a bigger motor such as this, I've now been thinking that perhaps it should be a dust extractor at the same time. So pretty much this design, except that the pipe for paint booth would go to a table saw instead. The motor could even be a wall-mounted extractor, though the cheapest ones don't seem to move as much air as construction air blowers and the like.
Super clean build! I definitely picked up some tips for my build. Thank you!
Smart build
Nice job!
Nice work on the video. You put a lot of thought into the design. Great job! You really caught my attention mentioning where you bought some of your supplies...Save big money...LOL. I worked for them for many years.
Save BIG Money at Menards!!! lol
Nice job. I just had a new furnace installed and plan on building just an air filtration unit with my old motor and cage. Thx for sharing.
They work great for that purpose. And they're pretty quiet too.
Interesting design.
That is badass
Good job,
Amazing video thanks for loading
Glad you enjoyed it!
Just subbed based on this video. It's incredibly well done. Now to watch the paint booth video.
More and more things seem to be in even metric sizes, and the inches specs are rounded. Good idea to measure and make sure for things like filters etc…
Nice❤
Awesome built Tommy and most importantly very good for the lungs!
wow first time Ive seen that router with a bearing....Awesome
It works great!
Nice job that is practical and cheaper that store bought ones. I know my buddy last year spent a fortune on his spray booth and had to get a sprinkler system to it as well but that's because he runs a business and safety requires he does that. Back to the build the portion of it that you made is very in-expensive and great job on making possible to have a affordable one in the average shop
Thanks! I think you meant to say the one I made is very "in-expensive" rather than "expensive"?
@@TommyTompkins lol is i did sorry about that.
Awesome job on the build and the video!
Excellent video. Bought the plans; appreciate the attention to detail. All the best to you.
Great idea and execution! Could you provide a link for the remote control outlet please?
Since paint molecules are larger than air, if you mount the filter at the very bottom you may get better filtration results at the booth. Great video!
Awesome work
This video help me a lot but can you tell me what program are you using it work pretty good
so how would one go about building a fume hood for working with acids that attack metals?
I used a downdraft range fan... Which is quite than everything else on the market. It's blows lots of air out and sucks a lot too. The good thing is I can find ducting on the market or from my work place.
Do you have a picture or a link to the one that you used? Any idea what the CFM rating is?
This is the best shop air cleaner build I’ve seen so far on UA-cam. I like that you used a powerful blower and not something like a box fan.
Thanks! It works really well and I found myself using it to cool down the shop in the summertime as well by pumping the hot air outdoors while sucking in air conditioned air from the house.
@@TommyTompkins Do you experience any pressure differences in the workshop, due to fan power. I'm guessing that in enclosed room it could cause some pressure discomfort.
great job!
i was thinking a sheetrock jack might have been able to lift the blower assembly, i like the duel usage my wife could use a paint booth add on
Very nice! Thank you for sharing.
OK so first of all, cheers to you Tommy for helping me solve two problems at once (get two birds stoned-Ricky) I couldnt log into my paypal account fast enough to buy the plans. For anyone considering buying the plans, they are very professionally done, almost like an actual book, not just some wordpad document like Ive seen done and been duped a couple times by. Money well spent. I bought a furnace blower in a plywood box that a dude was using as a blower fan. Was going to modify it to work as an air cleaner, but this solves my fume issue (fiberglass-polyester resin=styrene) as well. This just saved me probably close to a grand.
Awesome! Glad to hear that you like the plans! I still think this is one of the best additions to my shop that I ever made.
Thank you so much for the detailed video and especially explaining why you chose to have a belt driven motor mounted OUTSIDE of the fan 0:43
Yes that was really important. Fume fire hazard is something I was not actually even realising. Also this powerful fan (without filters) can suck in screws or some small metal chips, which could cause problem to engine living inside the duct system. Very smart indeed
Rather than measuring it all out could you use a sheet of peg board to mark where the holes need to be?
nice
great vid Tommy. The attempts to fit the unit to the ceiling looked exactly like me in my workshop...am sure I should get some help sometimes.
I am moving you to the top of my watch list you got some great ideas
Awesome! Thank you!
i want to use one of those remote receptacles but most that i find are huge. so i will get those power bars that are 4 feet long and can accept the biggest plugs.
That works too.
Nice design
Thanks Charlie! Hope all is well with you.
@@TommyTompkins Likewise! Are you going to George Vondriska's Meet the Maker event on the 17th?
@@JackbenchWoodworking I was thinking about stopping by. I’ll probably see you there!
@@TommyTompkins Great!
Love it!
Thanks!
Very nice....Somewhat a little over kill, but over all it's a nice set up.
Thanks Brian. I really don't see it as overkill at all. Sometimes I wish it was bigger! Haha
Hi! More rpm with pulleys will help to get perfect air flow..! 😉
Great design and well presented. You put a lot of thought and work that benefits us all, good job. The diverted part, did you think of using a a door type baffle instead of swapping the whole part?
Thanks! Yes, I did look at door type baffle's to start but none of the ones that I found sealed very well so I decided to make my own which seals MUCH better.
@@TommyTompkins I meant did you consider making your board a swing door? Should be easy to seal and a clasp to close.
After reading your comments throughout, I can see you thought this out more than most of us imagine. It works for you and it’s worth every moment you put into it.
I’m considering doing one for my garage which I use only in summer, so I won’t need filters to get rid of dust and humid air. I’m now looking at a blower setup thanks to your video, makes sense.
Don't see radial arm saw that often any more. Is really like one to replace my sliding miter saw.
Great project! Thanks for sharing!
Dope! This is worthy of startup of it's own
A startup?
Great detail! Looks like you are using it as an exhaust; why would you need a filter to pump air outside? You only need it when you are using the diverter to keep your garage air clean.
Thanks! The filters that I use when painting are only used to try and capture the majority of the overspray so that it doesn't cake up the inside of the fan blades at the siding on the outside of the shop.
Great job! Makes sense.
Pure genius! I'm absolutely going to build a version of this!! Thrilled i found your video, I'm subscribed and look forward to seeing more of your posts.
This is a great video do this work for a paint boo
Hi Tommy! I just caught up to this video looking for filter options and this is a great plan!
I, too, ran into the dimensional issues you noticed with the plywood. I found that Baltic Birch plywood is made to metric dimensions @ 18mm or .708 inches while American plywood is a genuine 3/4 inches or .75 inches.
Had me scratching my head till I researched it for myself. Take Care!
Great video! I noticed the MN shirt at the beginning and your company was lift bridge furniture so I decide to Google it and realized we live in the same city haha small world!
Awesome! Small world!
When spraying solvent based finishes you should use an explosion proof fan. You’re taking a very dangerous risk
On that vent you used that goes outside the vent has a screen in it that I’m sure you could get a lot more cfm out of the blower if you cut out that screen. I really like the design of the blower you built btw!
You might be right. I haven't cut out the screen because it still seemed like it wasn't very restrictive and has fairly large holes. I might give that a try though and see how it goes.
Wow, really great ideas and nice execution! I'm looking to make something like this but smaller scale.
I just wonder though, how to make this all setup to live outside (on balcony in my case).
First I just don't have space inside and the other thing I just would like to have this noisy devices outside.
This changes a setup quite a bit but still plentiful great ideas with your vid. Thank You
Just noticed your Reznor garage heater, is there any danger using that when you spray?
Great question! The presence of the Reznor heater actually contributed greatly to my decision to build this unit. I was getting ready to do a lot of spraying in the garage and with it being cold here in Minnesota, I knew that I'd have to keep the garage doors closed with the heater running. Obviously, that's a potential recipe for disaster. I knew I had to find a way to keep my shop heated while being able to vent fumes at the same time. I built this unit and used it with my spray booth to spray about 250 Pegs & Jokers game sets. That's a ton of spraying and it worked excellent at drawing out all the fumes. I could spray for hours, put everything down, step back 15 feet and not smell a thing. Speaking of combustible material...very fine sawdust floating around the air is also a potential explosion hazard. The air filtration feature of this unit helps to minimize that risk as well by removing all those fine particles. Here's a quote directly from Reznor:
"WARNING: Gas-fired appliances are not designed for use in hazardous atmospheres containing flammable vapors or combustible dust, or atmospheres containing chlorinated or halogenated hydrocarbons."
Nice project, Tommy. Excellent design and execution as usual. I truly enjoy watching you both design and build your projects, whatever they might be. Troy
Thanks Troy!
Very nice video and assembly. The MERV 7 prefilter dropped your blower flow significantly when you placed it in front of the 8 inch intake because you were only using the 8 inch round area of the filter, not the whole filter area. You'll see a lot less pressure drop if you fit that prefilter into a full-size housing in your paint booth before necking down to the 8 inch duct.
Looks like a swamp cooler motor and housing
I was told that it came out of a furnace.
I thought for any fan exhausting paint and possible solvents should be a fire or explosion proof motor as a safety precaution?
He explains it in the video, but his fan and the motor are separated. The only issue is the motor is still exposed to the elements of the shop that he is trying to evacuate. This design would work really well if it was blowing or exhausting in/out of a sealed room from the outside.
At this configuration, filters do not work in full capacity. Am I right? The inlet hole is small and placed too close to filters. It would be better if you have an expansion chamber before filters. It can be a square or pyramidal shape.
Initially, I was concerned about the same thing but when the filter gets dirty is fairly evenly covered. It works pretty well, but there's probably room for improvement.
I nearly had a stroke a couple of years ago when i went to buy some unistrut. Its 4 times high tgan it was 10 years ago. It wasnt cheap then.
Hi Tommy, I am from Viet Nam. please advise what software for your design. Thanks Tommy
Hello - I use Sketchup
Can you tell me more about the fan? 120 volts? HP? CFM? Output diameter? Thanks,
Paul
Yeah it's 120 volts but honestly, I don't know much else about it. It was a Craigslist find.
Great job. But need more intake air. 8 inch intake not enough
Props that is a really nice set up, did you use a uv resistant sealant on the exterior? I have found that some of the caulking out there will shrink over time when used outdoors.
Honestly, I don't remember if it was UV resistant but I think it was? It's held up great so far.

What do you do during the winter to help retain heat? I'm also in MN, want fresh air in my shop but also don't want to triple my heating bill!
In the winter, I mostly just use the filter which just recirculates the heated air in the shop. I don't do a lot painting in the winter, but when I need to use the exhaust vent, I'll crack the door.
@@TommyTompkins thanks for the reply! Very cool build!
@@TommyTompkins What effect does the paint fumes have on your unprotected heater when you do paint in winter while that is running? My contractor told me he would not honor warranty on the heater if painting indoors.
I like the idea! I’m trying to come up with something similar for my shop. But, when going to extraction mode how do you make up that air you are pulling out of the garage? I have a forced air furnace (and even with your reznor) don’t you risk pulling out too much air and furnace not working?
I have an air exchanger on my furnace that turn on and run to help bring in outside air while I'm running the shop in extraction mode, then I leave the garage door into the house open to create an air flow. It works very well. I've also run the shop in extraction mode without the air exchanger on and that works too, but you probably don't want it trying to pull air through every little crevice in the home. Another option would be to crack the garage door slightly so that it sucks in outside air while it's running.
Hey, question though: does that Reznor heater take... 9-inch nails??? Eh??? EH??? ^_^
Love this build! Great job!
lol!!!
Tommy
Nicely done sir! Very informative, nice workmanship. Can you share what size squirrel fan that is in CFM? And how noisy is it with it on? TY
Thanks! To be honest, I have no idea what the CFM is for the squirrel cage that I used. But it's very quiet and MUCH MUCH quieter than the first blower that you see in the beginning of the video. I think any standard size furnace blower / squirrel cage would do the trick.
Sweet project...I have a question while doing your airflow test did you take amperage readings off camera. Just wondering
Glad you like the project. No, I didn't take any amperage readings off camera.
so... if its a hot day.. do you simply shunt all that cool air into the badlands and then stave off heat strokes all day? sorry tldr..
Sorry tommy I might not explain my self I would love to know the name of program that you are using in your computer
Hello Hugo - the program is called Sketchup.
Great job, and great video. I see you painting at the end. My question is... do you see any paint on your siding outside your house?
No visible sign of paint or any discoloration on the siding outside. But I typically spray finishes like Arm-R-Seal and don't do a whole lot with bright colors.
@@TommyTompkins Thank you. I’m definitely following your channel.
colder climates this I think will pump warm air outside,,,,, leaving Vacuum to pull fresh cold air inside.... (Not sure if thats a bad thing)
Hello, Would you be able to comment on the horsepower rating of the motor itself? You have a pretty good shot of the motor spec plate but it's blurry. I've got a 1/4 HP motor I'm trying to replicate your build with but I'm not sure if it's enough power.
If I remember correctly, I used a 3/4 HP motor.
@@TommyTompkins @Devin Nasar - The motor is 1/3 HP - it's a Dayton model 5K282 - 1725 RPM, 6.2 Amp
@Devin Nasar - Your 1/4 HP motor would likely be adequate based on the fact that the motor in this video is 1/3 HP, not 3/4 HP as stated below.
Great video, Did you do anything for a fresh air inlet to offset the air you are removing from the shop?
Thanks! No, I didn't add a fresh air intake because I found it sufficient to just crack my garage door which allows it to suck in fresh air. In the winter when it's really cold, I open the door that goes into the house and turn on the air exchanger on my furnace and that seems to work well too while keeping the shop warm. Sometimes it's kind of a pain to crack the garage door since the wind can blow dust around so eventually I'll probably add a dedicated air intake somewhere.
I want to buy the plans but cant find the size of the fan you used I got one the other day but when I went to buy the plans it said 10x 20 filters way to small for mine
Oops! That's a typo. The filters are 16x20x1 NOT 10x20x1. I'll update the site.
@@TommyTompkins did you take any measurements of the blower you started with?
@@arose460 The plans were designed for a blower that is no more than
16-1/4” (412.75 mm) tall and 18” (457.2 mm) wide with some room to spare. If
your blower is larger, no problem. Simply modify the dimensions in the plans to
make your enclosure box a bit larger. If you’re modifying the original dimensions,
just remember to choose a filter size that will fit your enclosure dimensions (the
default filter size is a 16x20x1).
Tommy all I need is to make it taller sounds good to me. Thank you so much for your time.
Why put a filter when the air goes out behind the wall ???
You should make a box to cover the motor
Great job and video, Tommy! I will likely order and adapt your plans for a farm truck and equipment paint shop.
In a typical ac motor like that there aren't any brushes where sparks occur. No ignition possible.
Tommy, this was a Great Video addressing my concern on venting paint fumes. The utilization of a belt driven fan versus a box fan or explosion proof motor was brilliant. I have scoured the internet for the fan you used with no luck. I saw a comment below that someone thought it was a swamp blower. Your response was that you were told it came out of a furnace. Do you have any further details on the assembly and where one could be had? Thanks in Advance!
Hi Greg - I see them pop up all the time on Craigslist and Facebook marketplace for next to nothing. Here's a listing right now that has two of them: facebook.com/marketplace/item/925667761166094/ They clean up pretty well and you can always add new bearings. If you wanted to buy new, you can find them on Grainger but they'll be much more expensive: www.grainger.com/search?searchBar=true&searchQuery=belt+drive+blower
@@TommyTompkins Tommy, thanks for the quick response. About an hour after i sent you the message i did find several available commercially. I also agree with you that they are a little on the pricey side. Thanks again for the Brilliant Video. Its Gentlemen like you on You Tube that make me look smart in front of my neighbors when i plagiarize you ideas. LOL!!
@@gregoryhilker3739 lol! Well glad I can help make you look smart with the neighbors. Good luck finding a blower.
I'm no expert , just another nerdy DIYer. I don't think you need to double up (stack) the filters. The higher the Merv number the smaller the particle size the filter will, well filter. Two 6 Merv rated filters does not give you a 12 Merv rating. Additionally airflow is based somewhat on surface area. A 20X20 1in pleated filter has 4.7 sq feet of surface, while a 2in pleated filter has 8.1 sq feet, and 4 in has 15.4. The resistance on a 1 in. MERV 7 and a 4 in. MERV 11 are approximately the same. That being said. Great build!. I have been looking for ideas to combine both dust filtering and air extraction into the same system and this have given me some great design ideas.
I think you might have misunderstood how I'm using this. I'm not adding two filters to increase the Merv rating. The reason for using two filters is so that I can use a more expensive, higher Merv filter on the inside and a super cheap $2 filter on the outside. Since the outside filter catches the majority of the sawdust floating around, I can change those out several times before needing to change out the more expensive Merv filter on the inside. It's all a fine balance of saving my lungs, saving money, and preserving airflow. To be honest, it's been working out great and I wouldn't change a thing.
@@TommyTompkins Yes I thought that might be your reason.. but I was getting a little long winded... A great build, at some point I will probably build something similar. as painting in a garage in the winter time can be quite toxic.
holy smokes this is legit. how about I just pay you to make me a similar one for a paint booth
Okay then. Money talks!
@@TommyTompkins shoot me an email when you get a second and we will make that happen. eevanstn@gmail.com
Question: Why do you filter and vent the air?
Why not just vent the air?
Filtering is only used when recirculating the air. I don't filter the air when venting. Venting is only used when there are harmful fumes I don't want to breathe. In the winter time, my heating bill would skyrocket if I only vented and didn't filter and recirculate the warm air.
Nicely done! What is the exact brand/ part number for the remote power switch?
Thanks! I'm using this 3-pack for my dust collector, air filter, and shop lights: www.menards.com/main/electrical/light-switches-dimmers-outlets/wireless-controls/indoor-remote-outlets-3-pack/ylt-12/p-1444425969250-c-12683.htm
Maybe somebody already answer this question but what is the software the you use ?
Sketchup
@@TommyTompkins ok good and it's easy to use?
@@jopoitras There's a bit of a learning curve but once you get the hang of it, it's fairly easy.
A y-hose and blast gate would be simpler than that diverter contraption you’ve got going there, and no loose bits to lose.
I think you’d lose a lot of airflow going that route. I’m very happy with the contraption.
Nice detailed video and seem like an efficient way to keep the shop clean, thanks!
Thanks! It works very well. Over the summer I found that it also helps cool down the shop and pump hot air out while bringing fresh air in which is nice.
The handsaw didn’t do a really nice job with the cut.......you did. Excellent
Thanks!
What were the "cheap" blue fiberglass filters you got instead ? (brand) Thanks !
I found myself watching this video again, two years latter.
I’m looking at an “explosion proof” duct fan on ebay($250US)
It’s made in China, hopefully it’s not a scam…Could be a very dangerous scam for me.
🙏🏻😎🤜🏼🤛🏼🍀🇦🇺
I am always fascinated how them louvers know exactly when to open after blower is turned on ...
... at the outside vent
