You're quite welcome! Have fun with the shop (when you finally get it), and feel free to ask question in the comments of any of my videos, even if its not related to the video itself.
Just wanted to leave you a comment to let you know after watching your UA-cam about the Dust Deputy I got the one you were talking about the neatiease one and works just like you said always love your comparison of things and how tools that youdo.thank you so much for doing this for people.
Great test setup! 👏This is by far the most logical and fair comparisons I've seen so far. Your setup is top notch. Thanks for measuring the CFM throughput. 👍 The only thing i would suggest is to measure & compare (which others have already suggested) the amount of fine dust that makes it all the way to the vacuum filter. This can be done by wrapping a paper towel around the filter so you can see how much dust was captured. Another thing to consider is to make sure you thoroughly mix up your sample sawdust and divide it equally for each test. EVERY video I've seen so far REUSE the same pile of sawdust, which means that the first test unit already removed most of the finer dust, making the subsequent test units appear to have less fine dust residue. Not a fair test. Keep up the great job!
Thanks, Phillip. I totally get the idea of trying to make the test the same for each unit. I'm a retired software developer, so being able to run tests and get repeatable results is ingrained in me. But honestly, if I went down that rabbit trail, it might never end. 😂 So yeah, this was "good enough" (I cringe even as I write that).
Thanks for the video. I stumbled across an old festool dust distractor that was around 400$ new for around 100$. My home made cyclone has just gave up so I thought it was worst a try. I looked into to bags and filters and thought this thing will be expensive to keep running. That’s when I came across a video with a home made mount connecting the dust deputy to the top of the distractor. 135$ later I was done. It works amazing. I was saving up to put in a 1500$ set up, but after this, I have all I need. It so light and portable I can easily move it anywhere in my shop. My point is, for around 500$ you can take care of your dust collection in a two car garage shop. You probably won’t find a deal like I did but for the cheap festool collector (400$) and this cyclone you might find a good replacement for an experience set up. P.s. I ran my planner at its most aggressive settings to test it and my festool collector had absolutely nothing in it.
I have used a Dust Deputy for vacuum sanding drywall for about 5 years now. When the new one with the 'neutral vane' came out I bought a couple to see how they would work. My first thought was that the vane would interrupt the centrifugal force keeping the dust against cyclone as it spiraled down to the bucket. In fact that is exactly what it did putting the drywall dust into the vacuum air stream and on into the machine. Today I hooked up an old style DD and a new one in tandem. First test: machine - old style - new style - sander. Both pails were wiped out and dry. After a few minutes of sanding I opened them up and there was about the same in each one although the old style had more of the very finest dust than the new one. Second test: machine - new style - old style - sander. Both pails were again wiped out and dry. This time after a few minutes of sanding the old style had all the dust and only trace amounts in the new style. As I have several machines going on different jobs I've taken the top off the new DD's and cut the vane off as flush as I can to the lid to keep the drywall sanding dust forced to the outside of the cyclone til it gets to the pail. I guess it works differently with heavier dust and wood chips.
A couple corrections: 1. The generic one has the lid shaped to promote the correct flow, the "neutral vane" flap in Oneida's version is a cheaper way for them to do the same. They're a sheet metal company and didn't change their ways when designing for plastic the first time, that's all. 2. Those tapers and rubber adapters...you could just cut off the tapered parts on the Oneida and connect your hose straight to the larger diameter behind the taper for maybe even better (?) airflow.
Maybe, but what about longevity? Will it stand up over time? Will the particulates wear through the plastic used in the generic one faster than the name brand? Friction has to be a factor sooner or later in both of them.
@@thomasarussellsr Hi Thomas, I have had my generic cyclone for 4 years, it came from China. It still works brilliantly and has no sign of wear as I look every time I empty the bucket underneath it. Cheers, Huw
@@WoodenItBeNice thanks for the testimonial. Good to know. I just may have to bite the bullet as it is getting harder to sweep after ever day in the shop as I get older.

This was my first video of yours that I've watched. Ironically it's timing is perfect since I'm looking to make a dust separator and wasn't sure which I should choose. I'm going with the generic one since it's my first one and I didn't want to invest a lot right now. Thank you! I'm a new subscriber too. Also, the neatiease is UK now which when you add shipping the DD is about the same price or cheaper depending on which one you get. Mine came to $70.
I would wager that you could get +20-30% by replacing that flex with hard pipe & 90s, etc. (at least for the fixed parts). And if you ran this round of tests 5X, your data might vary 5-10% for any number of variabilities. If you have 10,000 people you need to get from hallway Point A to hallway point B, a straight hallway is your best option -vs- a narrow hallway with water fountains, lockers, chairs, stairs up & down, left and right turns, narrowing and expanding portals, etc. Keep it smooth, simple & laminar.
All that baffle does is to enforce circular flow on the inside, which cannot happen with the old dust deputy because the inflow impinges on the vertical pipe, screwing up some of the circulation.

Good video. When you test again, check the shop vac canister filtr for dust. Another interesting test would be to filter some drywall dust to see if any of the cyclones actually do a good job with fine dust.
Failed check fine particulate matter that was caught/stuck in shopvac filter. Visual observation is always tricky. Does seem results are somewhat comparable. I will however give some of your other videos a great thumbs up. Keep up the fine work.
Visual inspection was good enough. Anything else would require starting each test with a brand new filter, thoroughly cleaning out my tubes and pipes before each test, and having a set of sawdust that I could duplicate for each test.
These cyclones are only for filtering out the large particles so visual examination is enough. Your filters on the rest of your system are the ones that pick up the fine, more dangerous dust. The cyclones just help keep your fine particulate filters clear to do their job.
I'd be interested to see if adding a vane to the old DD would show the same improvements. Seems like its be easy enough to hot glue a similarly sized piece of sheet material in place. If that works it'd be even cheaper than buying another unit, and might be a good video idea.
A useful parameter to provide would be the differential pressure across each separator [inlet to outlet]. Of course, you'd require test connections and a good d/p gage. No big deal. Still informative vid, so THANKS. I have the cheap copy which is fine ...
Just slap a shim of wood in there, and since the basic design is the same, it should work. I expect doing so on the generic will also improve it as well.
Great video! I am so Glad I found your channel! Is it more amps that you want to have on a shop vac for better pick up? What is the ratings on yours? Thanks :-)
Thanks, and glad to have you aboard! Generally, shop vacs go by "peak HP", and mine is either 5.0 or 5.5 - I don't remember, and it doesn't say what it is on the outside.
So Amazon seller strikes again. Got this 10 mins ago. No hardware or seals of any kind included. Now I have to send it back and hope they send me a proper one. This was the no name
i like how they fix obvious design flaw in their product and call it a new feature )) (instead of making it just right in the first place like manufacturer of "generic one" did)
Thank you for the update and the extra step you took... Nope I was not going to use that joke again... LoLolOLOl But I had to laugh at the statement anyway... :-D Thanks Dan! LLAP
Funny how only USA uses HP in vacuums! This is pretty meaningless bloated number. In EU and rest of the world input RMS power consumption is used like 1200 W or 2000W. 5HP is 3700W!!
Great video, but I wished that you would have cleaned the collection bin, between tests, then I would have had more idea which one did a better job on filtering out the fine dust, because this is the main reason we use them, to protect our lungs, and to increase the life of the vacuum filter, because it's the fine dust that does the damage. I wonder if there would be an improvment in fine dust filtration, if two Dust Deputys were plumbed into each other in series, from the same vacuum
Actually, shop vacs don't do *any* fine dust collection, if you're using the commonly-used definition of "fine dust". You need a blower-type system, with at least 4" pipes, as well as good dust collection ports at the tools. And even then, if you don't vent the blower outside, you're probably just creating a "dust pump". See billpentz.blogspot.com/ for more information. But if you're just talking about the sawdust you typically see in a dust collection bucket, then that depends on a lot of factors, including (but not limited to) whether the extra suction will affect the individual tool or not (in my case, the table saw). How it affects my personal system would be irrelevant, unless your setup was identical to mine. I hope that makes sense.
A well-fitting mask with interchangeable filters (or a good quality "single use" with all-round rubber seal) is a must in addition to dust collection with routers and sanders. Also it is good to get the unwoven rag type (i.e. not paper) bag for your vac and use it even with the cyclone...or just regularly clean the filter with a dedicated/clean brush and wash it on occasion if washable (check if re-oiling is needed).
@@TheNewbieWoodworker depends, most industrial collector bags are just for shavings, so yes, afterfilter and outside, that's why a shop-vac is heaps cheaper in terms of quality of filtering than the big fittings (as long as you can make it work with the lower performance).
Thanks for the comparison but it would have been better comparing by weight. This would have shown how much fine dust got through to the vac filter. Any chance you can do it again but by weight? Just need to weight the filter before and after each test. Thanks
Mate the best video for my requirements answered every one of my questions except one ...what is the maximum air flow rate through either of the cyclones I have a vacuum system I am concerned the orifice of 50mm is placing labour on the vac motor at full speed so I operate it at half and since watching your awesome video I have decided to just add another cyclone this doubling the efficiency of airflow so half the stress on the vacuum motor.
When testing you must use copied samples weighted out and sived to proper size bits, this is the only way you get a definitive results. Either way once your 3/4 past full.on your collection tank any more dust will go into the vacume.
Feel free to do that thorough a job of testing. Just a warning, though: You'd also need to make sure you started with a brand new filter in the vacuum, for each test, otherwise you're not comparing similar setups. You'd also have to make sure the piles of dust are the same consistency, stacked the same way, and make sure you suck it in in the same rate for each test. In other words, it's a slippery slope, with attempting to get scientific results. I think my results are "good enough" for most people.
Thanks for letting me know. There is one generic one there, but it's not Amazon Prime and I don't know how reliable the shipping would be. I wonder what happened? Did DD win a lawsuit, or is it just a supply issue?
I realize this is an old video, so I’m wondering if you’d take a look at the newest Deputy, and compare it with the numbers on this video? You should also compare the inlet and outlet sizes. Thanks.
If you're talking about the DD 2.5, then I have been using it for a while now. For the hose from the vacuum to the DD, it's a fairly standard size. The hole for the hose that goes to your dust collection run is an odd size - if you can use the hose that comes with it, then no problem. Otherwise you'll need to figure out how to pry the adapter off their hose and use it with your own hose. The unit definitely has better sucking power, and seems to work just as well. I don't have any comparison numbers, though, but there definitely is a fairly large difference in sucking power.
I know this video is a year old but the one thing I don't see in these types of videos is why not find two five gallon buckets full of dust not tiny chips but actual sawdust the fine particles suck 10 gallons of sawdust and then see how much ends up in the vacuum cleaner. I'm talking push it to the limits. Yes, you might have to empty the Dust Deputy bin twice or three times but with a lot of volume it would be a better test when checking the Shop-Vac filter.
Well, it's important to test it as it actually is used. Sucking up 10 gallons of sawdust is not a fair test, because it's never (or rarely) used that way, and it's probably not designed to handle that much at one time anyway - the vortex would get so full of dust it wouldn't work right. I understand your point, but honestly, if I were to start trying to get more scientific, where should I stop? I'd need to make sure the dust is fed in the same way for each separator, in the same volumes at a time. That's just not a level of detail I have the time or interest in. The real question is, does it work, and work well enough (or better in this case), or doesn't it?
@@TheNewbieWoodworker I'm not disagreeing with your test method or the video. I would just like to see someone do a test under what I would consider real conditions. If someone vacuumed their shop area after building a cabinet for a piece of furniture, they might fill the Dust Deputy halfway full. You'd of course dump that into another container and save it till the next time you did some woodworking and made another mess. After a half dozen emptyings of the Dust Deputy, what's in the vacuum? Zero or a little bit. I'm going to assume just a little bit. In real life nobody vacuums up a cup or two of sawdust and then empties the Dust Deputy and the vacuum. Most people that I've worked around don't change the filter or even look at it until the pleats are totally full of sawdust and the vacuum is barely working. That's what I mean by a more realistic test. Again, your video is great. Id just like to see a larger scale test. I'll dig around and see what I can come up with.
@@randywl8925 Thanks. There's a YT channel called Project Farm, or something similar, and they do a lot of thorough testing. I wonder if they've done one on dust separators?
Those are some wildly high CFM numbers for a shop vac. I have never seen one pull more than about 150 CFM. Are you sure you have that tester set correctly?
I'm pretty sure I mentioned that the numbers don't represent true CFM, because I dont have the device configured correctly. The numbers are really only valid when used to compare against each other.
I went to the Amazon & looked at the generic dust collector & saw that it does not come with any gasket does it need a gasket if so what do you recommend to use for a gasket
I notice there is a Dust Deputy 2.5, which has physically bigger, and has larger 2.5" ports. More expensive at $55 instead of $30 for the 2" version. Would you recommend just getting the dustdeputy 2.5 instead?
Yes, I would. I have one and it's great (mostly). It uses ports that are closer to standard size (although they still aren't perfect), and the airflow seems to be improved.
SOrry, that previous comment was from me, but under another account. To reiterate: Yes, I would. I have one and it's great (mostly). It uses ports that are closer to standard size (although they still aren't perfect), and the airflow seems to be improved.
Of all the videos I've seen about cyclone separators, their "separating efficiency" are all about the same. The real comparison is in the airflow. 700 cfm is pretty darn good for a wet/dry vacuum-based set up. I have a Ridgid vacuum (12 gal/6hp) and I only get 181 cfm at the vacuum inlet. Maybe I calculated wrong but I measured 3701 fpm with an anemometer through a 2-1/4" diameter inlet on the vacuum. Using CFM calculations found online, that came out to 181 cfm. Looking at the specs for the vac, they say it delivers about 140 cfm. How in the world are you getting 700 cfm on the other side of the Dust Deputy? I'm using a Dustopper with the rig #JohnBuildsIt designed and I'm only getting 77 cfm (1772 fpm through 2" opening) on the other side of the Dustopper, i.e. at the end of the hose, and 96 cfm without the hose (1969 fpm through 2-1/4" opening). Not trying to impune your work, just trying to understand.
@@TheNewbieWoodworker ah, I missed that. Can you give us a measure of the airflow at the vacuum, with no hoses? I'd be interested to know how much the Dust Deputy knocked it down. While the Dustopper does a good job at "separating", it cuts the airflow by more than half by the time you get to the tool end of the system. Caleb, at #YouCanMakeThisToo, did a video on the airflow difference between the Thien-type cyclone that he made and the Super Dust Deputy. They both worked well for him, but he found that the Super Dust Deputy didn't restrict as much airflow as his homemade cyclone.
@@awlthatwoodcrafts8911 Honestly, no, I don't want to know how much effect the DD has on airflow from the vac. It's one of those things that if I don't know, it'll never bother me. But if I *do* know, then it might drive me crazy. I hope that makes sense. 😄
@@TheNewbieWoodworker perfectly. I'm the opposite. I gotta know, even if it will drive me crazy. Now that I know, I'm upgrading my dust collection, at least for my table saw. 77 cfm doesn't cut it trying to suck dust out of a cabinet.
@@awlthatwoodcrafts8911 I totally understand. But before you do, consider this: Do you know for sure that upgrading your system will in fact get rid of the dust in your table saw's cabinet? What if you go through all that trouble, and it doesn't help? So if it were me, I'd do some research about my particular saw, to find out if upgrading the DC will help. Just a thought.
What is the height of the dust deputy from top to the bottom of the HD bucket? The dust separator I have now is not as effective specially fine dust like MDF.
"Insert" requisite joke about suction seems to be yet another joke inside the joke about the joke... oh no... it's a recursive joke! And BTW: it's probably unwise to invite YT Joke comments... No doubt you're gonna get 'em, this ought to be entertaining! I'll check back in a day or so 😁 BTW: Since you have 3 dust separators, any plans what you'll do with them? I'm thinking I'll get the generic one since I don't have anything at the moment.
I hadn't even thought about the "insert" joke. Must be getting too old. 😂 I have 3 extra separators, actually, including a Dustopper. I have no idea what to do with them. Got any ideas? 😄
@@TheNewbieWoodworker The unused dust collectors will sit there and "collect dust" LOL, I'm not sure what to do as far as projects go because you did the comparison... Maybe have a contest or give-away? I am considering buying the generic one, the $30 price is low enough it is probably not worth the effort to buy it from you and the shipping involved... on the other hand... the idea that they sit there unused makes me feel sad.
@@raymitchell9736 You know what's worse than that? I have a finished semi-mini-router table gathering dust also (good joke, by the way), and it has my lever-operated router lift inside it. I don't know what to do with it either. I made it for a project, and it's "OK" - it works. It even has a drawer for router bits. But I have no idea what to do with it. It's too big and bulky to ship, so I'm at a loss. I'm *this close* to just cutting it up into scrap.
@@TheNewbieWoodworker You've got to be kidding... wow that is sad too. Maybe take it apart and repurpose the pieces? You know, another thought came to me: if there is a problem this could be an opportunity. I'm sure other people have the same issue, you can make a video of "what to do with unused projects" or ask your viewers "what would you do with this?" This happens to me too: Sometimes I upgrade something in my shop, then what do I do with the old one?
@@carterscustomrods Nah, sometimes just laughing to myself is good enough. Besides, at age 64 I should be able to show restraint. Emphasis on the word "should". 😂
Interesting review, but I think you need to check your units of measurement. In order to get 700 cfm through a 2" fitting it would require a velocity over 32,000 fpm. You ain't going to get there with a shop vac!
They're all over Aliexpress and Temu. They have another version that is two cyclones with a second one dumping into an included small narrow transparent bucket. I'm about to find out if it's any good. :)
If it works as well, which it looks like it does, I'll take the cheaper Chinese import over the expensive US import. $50 for the one from China versus $100 for the DIY Dust Deputy.
I wish they made a 4 inch connection so I would not lose half of my volume from my dust collector ( not a vacuum but an actual dust collector). Vacuums are not really dust collectors as they do not pick it upas it is leaving the cut in most cases. It is more of a clean up the floor dust collector than the unit that actually can extract dust from the air as it is being created. So in short, I need a 4 inch hose connection not 2 inch.
@@TheNewbieWoodworker Yes, thank you I have seen those but the cost is $179 and increases the footprint with a 15 gallon container. The scoop over my lathe is 4" but choking it down to 1 3/4" inlet really reduces the pressure from the dust collector. I may need to go large, but was trying yo be mindful of space.

Thanks for your response.
All that baffle does is to enforce circular flow on the inside, which cannot happen with the old dust deputy because the inflow impinges on the vertical pipe, screwing up some of the circulation. The generic has a wider top such that the inlet is actually tangent to the wall. And plus it has the spiral, which in combination end up putting a baffle in about the same spot. The bottom line is that the old dust deputy was a defective design and the kludged it by putting in that baffle.

Good video. When you test again, check the shop vac canister filtr for dust. Another interesting test would be to filter some drywall dust to see if any of the cyclones actually do a good job with fine dust.
Thanks. No, they won't do a good job with fine dust. That's a complex topic, and one I won't be tackling. 😏
Failed check fine particulate matter that was caught/stuck in shopvac filter. Visual observation is always tricky. Does seem results are somewhat comparable. I will however give some of your other videos a great thumbs up. Keep up the fine work.
Visual inspection was good enough. Anything else would require starting each test with a brand new filter, thoroughly cleaning out my tubes and pipes before each test, and having a set of sawdust that I could duplicate for each test.
These cyclones are only for filtering out the large particles so visual examination is enough. Your filters on the rest of your system are the ones that pick up the fine, more dangerous dust. The cyclones just help keep your fine particulate filters clear to do their job.
This was really helpful. Thank you for sharing it!
You're quite welcome! 😄
Hey Dan, thank you for the extra effort.
You're quite welcome! 😄
I'd be interested to see if adding a vane to the old DD would show the same improvements. Seems like its be easy enough to hot glue a similarly sized piece of sheet material in place. If that works it'd be even cheaper than buying another unit, and might be a good video idea.
A couple of other people mentioned that idea. Here's a pic to show where it might go: ua-cam.com/users/postUgxYf3gdy8Cbe18Kk4V4AaABCQ
A useful parameter to provide would be the differential pressure across each separator [inlet to outlet].
Of course, you'd require test connections and a good d/p gage. No big deal.
Still informative vid, so THANKS.
I have the cheap copy which is fine ...
I get it, but that's above my pay grade. :)
Thanks, great comparison! Now I wonder if one could just modify the old dust deputy and get similar result.
Thanks. Other people have wondered the same thing. I posted a pic on my Community tab that may help.
Just slap a shim of wood in there, and since the basic design is the same, it should work. I expect doing so on the generic will also improve it as well.

Great video! I am so Glad I found your channel! Is it more amps that you want to have on a shop vac for better pick up? What is the ratings on yours? Thanks :-)
Thanks, and glad to have you aboard! Generally, shop vacs go by "peak HP", and mine is either 5.0 or 5.5 - I don't remember, and it doesn't say what it is on the outside.
Adding a cyclone actually gives you better suction than without one because your filters stay cleaner.
Great followup!

Thanks, and you're welcome! 🙂
Great video, but I wished that you would have cleaned the collection bin, between tests, then I would have had more idea which one did a better job on filtering out the fine dust, because this is the main reason we use them, to protect our lungs, and to increase the life of the vacuum filter, because it's the fine dust that does the damage. I wonder if there would be an improvment in fine dust filtration, if two Dust Deputys were plumbed into each other in series, from the same vacuum
Actually, shop vacs don't do *any* fine dust collection, if you're using the commonly-used definition of "fine dust". You need a blower-type system, with at least 4" pipes, as well as good dust collection ports at the tools. And even then, if you don't vent the blower outside, you're probably just creating a "dust pump". See billpentz.blogspot.com/ for more information.
But if you're just talking about the sawdust you typically see in a dust collection bucket, then that depends on a lot of factors, including (but not limited to) whether the extra suction will affect the individual tool or not (in my case, the table saw). How it affects my personal system would be irrelevant, unless your setup was identical to mine. I hope that makes sense.
@@TheNewbieWoodworker Thanks for your reply. It seems like it's a more complex problem than I thought it was
@@richardevans9465 LOL. When I started researching fine dust collection, I wished I could have gone back and taken the blue pill. 😄
A well-fitting mask with interchangeable filters (or a good quality "single use" with all-round rubber seal) is a must in addition to dust collection with routers and sanders.
Also it is good to get the unwoven rag type (i.e. not paper) bag for your vac and use it even with the cyclone...or just regularly clean the filter with a dedicated/clean brush and wash it on occasion if washable (check if re-oiling is needed).
@@TheNewbieWoodworker depends, most industrial collector bags are just for shavings, so yes, afterfilter and outside, that's why a shop-vac is heaps cheaper in terms of quality of filtering than the big fittings (as long as you can make it work with the lower performance).
Glad to know the Chinese one works. Dust Deputy is just too expensive here.
They charge what they can get, just like everyone else. But yes, for a piece of plastic, it does seem to be overly expensive.
Generic cyclone does have neutral vane - curved top smoothes the stream and acts like such.
Interesting, thanks! 😄
And you can add a piece of metal or plastic inside the old deputy.
@@dushk0 👍
Thanks for the comparison but it would have been better comparing by weight. This would have shown how much fine dust got through to the vac filter. Any chance you can do it again but by weight? Just need to weight the filter before and after each test. Thanks
I understand what you're saying, but no, I'm not going to do that. You're welcome to try it out, though.
Mate the best video for my requirements answered every one of my questions except one ...what is the maximum air flow rate through either of the cyclones I have a vacuum system I am concerned the orifice of 50mm is placing labour on the vac motor at full speed so I operate it at half and since watching your awesome video I have decided to just add another cyclone this doubling the efficiency of airflow so half the stress on the vacuum motor.
Thanks. Honestly, I'm not sure. I have an anemometer, but I can't figure out how to set the paramers on it.

When testing you must use copied samples weighted out and sived to proper size bits, this is the only way you get a definitive results.
Either way once your 3/4 past full.on your collection tank any more dust will go into the vacume.
Feel free to do that thorough a job of testing. Just a warning, though: You'd also need to make sure you started with a brand new filter in the vacuum, for each test, otherwise you're not comparing similar setups. You'd also have to make sure the piles of dust are the same consistency, stacked the same way, and make sure you suck it in in the same rate for each test. In other words, it's a slippery slope, with attempting to get scientific results. I think my results are "good enough" for most people.
What is the nuetral vein your talking about? A air deflector inside?
Yes, that's exactly it. The air comes in through the horizontal port (tube), and is deflected by the "neutral vein".
Very cool! Unfortunately, it seems the generic version is no longer on Amazon...
Thanks for letting me know. There is one generic one there, but it's not Amazon Prime and I don't know how reliable the shipping would be. I wonder what happened? Did DD win a lawsuit, or is it just a supply issue?

Thanks really helpful video, buying the generic version
👍
Thank You for the review.
You're quite welcome! 🙂
I realize this is an old video, so I’m wondering if you’d take a look at the newest Deputy, and compare it with the numbers on this video? You should also compare the inlet and outlet sizes. Thanks.
If you're talking about the DD 2.5, then I have been using it for a while now. For the hose from the vacuum to the DD, it's a fairly standard size. The hole for the hose that goes to your dust collection run is an odd size - if you can use the hose that comes with it, then no problem. Otherwise you'll need to figure out how to pry the adapter off their hose and use it with your own hose. The unit definitely has better sucking power, and seems to work just as well. I don't have any comparison numbers, though, but there definitely is a fairly large difference in sucking power.
I made my own and ended up being more but hey, it was fun
I'm all for making things yourself, if it's fun. I actually tried to make one a while ago, and I failed miserably. That was *not* fun. 😂
What material/s did you use?

Thanks, and you're quite welcome! 😄
I know this video is a year old but the one thing I don't see in these types of videos is why not find two five gallon buckets full of dust not tiny chips but actual sawdust the fine particles suck 10 gallons of sawdust and then see how much ends up in the vacuum cleaner. I'm talking push it to the limits.
Yes, you might have to empty the Dust Deputy bin twice or three times but with a lot of volume it would be a better test when checking the Shop-Vac filter.
Well, it's important to test it as it actually is used. Sucking up 10 gallons of sawdust is not a fair test, because it's never (or rarely) used that way, and it's probably not designed to handle that much at one time anyway - the vortex would get so full of dust it wouldn't work right. I understand your point, but honestly, if I were to start trying to get more scientific, where should I stop? I'd need to make sure the dust is fed in the same way for each separator, in the same volumes at a time. That's just not a level of detail I have the time or interest in. The real question is, does it work, and work well enough (or better in this case), or doesn't it?
@@TheNewbieWoodworker I'm not disagreeing with your test method or the video.
I would just like to see someone do a test under what I would consider real conditions.
If someone vacuumed their shop area after building a cabinet for a piece of furniture, they might fill the Dust Deputy halfway full.
You'd of course dump that into another container and save it till the next time you did some woodworking and made another mess.
After a half dozen emptyings of the Dust Deputy, what's in the vacuum? Zero or a little bit.
I'm going to assume just a little bit. In real life nobody vacuums up a cup or two of sawdust and then empties the Dust Deputy and the vacuum.
Most people that I've worked around don't change the filter or even look at it until the pleats are totally full of sawdust and the vacuum is barely working. That's what I mean by a more realistic test.
Again, your video is great. Id just like to see a larger scale test.
I'll dig around and see what I can come up with.

Those are some wildly high CFM numbers for a shop vac. I have never seen one pull more than about 150 CFM. Are you sure you have that tester set correctly?
I'm pretty sure I mentioned that the numbers don't represent true CFM, because I dont have the device configured correctly. The numbers are really only valid when used to compare against each other.

@@moldyzucchinis3251 👍
Of all the videos I've seen about cyclone separators, their "separating efficiency" are all about the same. The real comparison is in the airflow. 700 cfm is pretty darn good for a wet/dry vacuum-based set up.
I have a Ridgid vacuum (12 gal/6hp) and I only get 181 cfm at the vacuum inlet. Maybe I calculated wrong but I measured 3701 fpm with an anemometer through a 2-1/4" diameter inlet on the vacuum. Using CFM calculations found online, that came out to 181 cfm. Looking at the specs for the vac, they say it delivers about 140 cfm.
How in the world are you getting 700 cfm on the other side of the Dust Deputy?
I'm using a Dustopper with the rig #JohnBuildsIt designed and I'm only getting 77 cfm (1772 fpm through 2" opening) on the other side of the Dustopper, i.e. at the end of the hose, and 96 cfm without the hose (1969 fpm through 2-1/4" opening).
Not trying to impune your work, just trying to understand.
If you pause the video around 1:59, you'll see the explanation for why the numbers are the way they are. Let me know if that explains it for you.
@@TheNewbieWoodworker ah, I missed that.
Can you give us a measure of the airflow at the vacuum, with no hoses? I'd be interested to know how much the Dust Deputy knocked it down.
While the Dustopper does a good job at "separating", it cuts the airflow by more than half by the time you get to the tool end of the system.
Caleb, at #YouCanMakeThisToo, did a video on the airflow difference between the Thien-type cyclone that he made and the Super Dust Deputy. They both worked well for him, but he found that the Super Dust Deputy didn't restrict as much airflow as his homemade cyclone.
@@awlthatwoodcrafts8911 Honestly, no, I don't want to know how much effect the DD has on airflow from the vac. It's one of those things that if I don't know, it'll never bother me. But if I *do* know, then it might drive me crazy. I hope that makes sense. 😄
@@TheNewbieWoodworker perfectly. I'm the opposite. I gotta know, even if it will drive me crazy.
Now that I know, I'm upgrading my dust collection, at least for my table saw. 77 cfm doesn't cut it trying to suck dust out of a cabinet.
@@awlthatwoodcrafts8911 I totally understand. But before you do, consider this: Do you know for sure that upgrading your system will in fact get rid of the dust in your table saw's cabinet?
