DUST COLLECTION SYSTEM! SHOP VAC GOOD ENOUGH FOR A DUST COLLECTION SYSTEM?
DUST DEPUTY LINK- amzn.to/2Btp5w9
ROCKLER 2 1/2' BLAST GATES- amzn.to/2R0B7Hb
Hi everyone! Here is a much needed review for all wood workers and shops that are interested in their own dust collecting system! This test, in my opinion, will make any person happy with the results as it will be easier on your wallet when it comes to this project!
This video includes a dust collection system, shop vac style vacuum, dust collection fittings and the Dust Deputy and how it works.
Why does anyone need a shop dust collecting system? A dust collector will assist with keeping you healthy and your shop clean! Dust will avoid your lungs and enter the shop vac. It will suck the majority of the dust through the piping of the dust collector and stay off your wood shop floor!
Thanks again for watching this dust collecting video! All support is greatly appreciated!!!
-Alex Q - แนวปฏิบัติและการใช้ชีวิต
I have a 2” system with the same Dust Deputy mounted on 2 Home Depot 5 gallon buckets(one inside the other to prevent collapse) connected to a Ridgid 5.0 HP vacuum and I feel the system sometimes has to much suctioning power. If I placed that plastic bag near any of my ports it would’ve violently ripped it out of my hand. Yours has power and will work, but I think you need to either get a more powerful vacuum or reduce the size of the catch bucket and your results will be much better. You did a great job installing the pipe! Double check if you have leaks in the system. I noticed with all your blast gates closed the sound of your vacuum didn’t change, indicating something open or a leak. 👍🏻👍🏻
I use the size 1 and 1/0 Mustad hooks to freeline for snook th-cam.com/users/postUgkxzXmlErSqVAEGWFEKO530BvTqFDw53QW3 and they have been fantastic. The points are super sharp, and the hook is small enough to blend with my baitfish, yet large enough to land fish 30" or more. I also use these hooks when I'm pier or surf fishing with my kids. They tend to catch tons of smaller snapper, whiting, and catfish, and we get far fewer gut hooks with these Mustad in-lines, which means more of them survive after release. I was actually using these hooks when I caught my friend too, but I think that had more to do with the bait I was using ;-)
I would have preferred to see the wood chips being vacuumed vs watching them in the dust deputy. Obviously they end up there, but the performance/suction at the end node seems like it would be more crucial to see.
CFM vs. Static Pressure, defined
Air volume is measured in cubic feet per minute (CFM) or liter per second (l/s)--the volume of air that the device can move from its intake to its exhaust in a given amount of time.
Static pressure is measured in inches of water (often referred to as inches water column, or inches WC), as in, how many inches the suction device can lift water up a pipe, or in millibar (mbar).
In simple terms, static pressure determines how much resistance (“static pressure loss”) your dust collector can overcome in order to move a given volume of air through the hoses and pipes. When it comes to designing a dust collection system, the raw CFM figure is initially more important than the raw static pressure figure, though static pressure does come into play once you start designing your ductwork (more on this later).
Is that enough CFM and static pressure?
WOOD Magazine has a great article on calculating CFM and static pressure requirements for dust collection. Although the worksheets in the article may look intimidating at first glance, they aren't too difficult to fill out. The article includes some typical CFM requirements for various tools, some of which I've included or summarized below.
Table saw, radial arm saw, miter saw, bandsaw: 350 CFM, 165 l/s
Belt, disc, or drum sander: 350-550 CFM, 165-260 l/s (depending on size)
Table-mounted router: 195 CFM, 92 l/s
Thickness planer, up to 13": 400 CFM, 190 l/s
Thickness planer, 14"-20": 785 CFM, 370 l/s
Now let's look at some contenders for an entry-level dust collection system. As of this writing, a ”6.5 peak horsepower” Shop-Vac® vacuum rated at 9.3A@120V produces 185 CFM (87 l/s) of airflow and 64 inches (160 mbar) of pressure. That's not even adequate for the least-demanding machine in the list, falling 10 CFM (5 l/s) short for a router table. In practical terms, this means the vacuum won't be able to produce the recommended 4000 FPM (feet per minute)/2 m/s (meters per second) linear air velocity necessary to capture most of the dust particles produced by the tool. (Note that the 4000 FPM/2 m/s figure somewhat oversimplifies things but it is a good, convenient figure for making realistic estimates.)
By comparison, a 1hp Grizzly dust collector rated at 8A@110V produces 500 CFM/235 l/s and 2.76"/7 mbar of static pressure. As you can see from the CFM figures above, under ideal conditions this dust collector should be able to capture most of the dust from most tools except larger sanders and 14" or larger planers.
Remember, I said that was under ideal conditions. This is where static pressure comes into play. Every inch of pipe or hose, every turn, and every change in diameter produces resistance which your dust collector (or vacuum) must overcome. You can use one of the various static pressure calculators such as Bill Pentz's static pressure Excel spreadsheet to calculate the static pressure drop produced by your ductwork and hoses. For the Grizzly 1hp dust collector we looked at earlier, the total static pressure drop can be no more than 2.76"/7 mbar. If you plug only 500 CFM/235 l/s and 7 feet (2 m) of 4" (10 cm) flex hose into the calculator, you'll see the static pressure drop is almost 3"/7.5 mbar, so we already need to look at a more powerful dust collector.
Although this is the simplest way to size a dust collector, you don't suddenly go from 500 CFM to 0 CFM. The excessive static pressure loss simply reduces the airflow through the system. Some manufacturers or magazines provide the CFM curves at various static pressures, which is helpful in determining whether you can sacrifice a few CFM for a longer run of pipe or hose while maintaining the recommended 4000 FPM air velocity.
Other considerations
In addition to the fact that a Shop-Vac just isn't suitable for stationary power tools, one of the dust collector's greatest advantages over a Shop-Vac is that it has a larger hose and is less likely to clog from chips and shavings. Whereas a Shop-Vac typically has a maximum hose size of around 2-1/2 inches/6 cm, a dust collector hose (or pipe) is typically 4 inches/10 cm or larger and is less likely to clog.
Getting back to your questions, you asked whether a dust collector can (1) pick up or (2) filter things that a shop-vac can't. We've already answered the first question (yes, a dust collector can “pick up” more). HEPA-rated filters can remove 99.97% of particles down to 0.3 microns. You can buy these types of filters for both Shop-Vacs and dust collectors, so technically the answer to the second question is yes but it just depends on what type of filter you buy (and, in some cases, how determined you are to adapt such a filter to your machine if your manufacturer doesn't offer one).
Of course, even the best dust collector will not capture all the dust, and even if you pony up the cash for a HEPA filter your dust collector will disperse some amount of fine dust back into the air. That is why you should try to exhaust your dust collector outside if it is practical (while also venting outside air back into the shop), and you should still wear a well-fitted respirator with replaceable P100 (HEPA-equivalent) filter, regardless of any other precautions.
Very helpful, thank you.
Hi Alex. I don't often respond to workshop videos (there's not a lot of really new and innovating stuff out there). You've done a great video here. But I would really like to commend the great father that you are. You have a wonderful son, and that is in every way due to your respect and treatment of him.
When I first setup my small shop I tried doing a system like this and though it did work it fell short on doing it effectively, meaning I had to always cleanup around the cutting area. CFM is paramount! you can have suction at each location like you have demonstrated but if you are not moving the CFM you just can't move enough air to really grab all the chip and dust from the tool (especially the table saw). I wound up getting a Grizzly G0703 2 stage in polar white on close out for around $650. I ran it using 4" pvc drain pipe with a total length 50' using 7 - 4" blast gates! It takes care of my Lethe, Band saw, Table saw, Miter saw, Belt sander, Spindle sander and CNC. Cool build and it is better than nothing! but once you have spent time with it you will eventually see the short falls.
Exactly what I suspected would happen. Currently I just hook my shop vac to whatever tool I'm using at the time, and I know when the filter is clogged because it just doesn't have the cfms sick in the dust. I bet this will ultimately act just like a shop vac with a clogged filter. Yes it still has suction, but just doesn't get the job done
This is one of the most complete and detailed dust collection setups I've ever seen. Well done!
I've never seen anyone do a video with a Dust Deputy on a larger trash can like you did. This was very well done, and very well explained. If I may offer a suggestion to you, it would be to always have at least one blast gate open while your shop vac is on. Having all the blast gates closed puts a lot of strain on the vacuum motor. Even if it's for just a few seconds until you get to the desired tool, all those seconds each time you turn the vacuum on, add up, and eventually can cause damage or failure to the shop vac.
I think it's awesome that you're bringing your son into the workshop to get him interested in learning something that is no longer being taught in most schools.
I’m having a hard time believing that the Craftsman vac will have the CFM to handle that planer. Best I can tell is that you can get about 115 CFM from that vac. I run that same planer on a 165 cfm dust collector directly connected and the planer still over powers the system and I have to relieve the positive pressure created in the system which allows chips to escape freely.
Fantastic setup and demonstration. Thank you for sharing it, subscribed.
Thanks for the video I have been researching dust collection for my small work area.
Such an easy walkthrough. You answered a couple key questions for me. Thank you.
I have been using a setup similar to yours for several years in my turning shop. I only use three outlets to my piping, and leave enough hose at each to clean that area. My turning shed is adjacent to my garage, so to cut down on noise I moved my vac to the garage and added a remote outlet from home dept. ( Westek RFK1606LC ) I can now listen to the radio while I turn. - Good video - The Dust Deputy is great!
Thanks for the demo! I'm going to consider this configuration!
Great example and setup, puts my mind at ease picking one up for myself. Thanks!
I am a believer- I am going to start working on mine now!! Thank you
Alex Thank u for taking the time to share. I am deplored right now but we will watching your videos. and emulating your shop. G'd bless you and America. Know that we are ready and orders have been given.
Thank you so much!! This is what I was looking for. You answered my question about using 2" pipe and a shop vacuum!! Cheers 🍻
Thank you , just trying to learn all I can on how to best approach a set up and I like yours
It'd be nice to see an update on this video. I can't see this working with planer and table saw. I think the planner will clog the small pipe. And there isn't enough cfm for table saw.
I made one of these for dust collection, I used a HF 4 horsepower vacuum and it works great , if the five gallon bucket starts to cave in the sides , the line has a clog in it and will cause this to happen, picking up aluminum chips will cause this to happen. Great job on the video .
Man, i wish i could thumbs up this more than once for getting your son involved. Good on you man. Great shop too. Going to go watch more of your vids to help support ya.
Good video. Can you do a video showing the dust collector working with the tools like the mitre saw and router?
Nice setup and explaining how you did it.. Still far from cheap but 1K+ to a $130 shop vac.. You have a winner
Cool vid and a very polite/friendly/genuine comments section. Good job guys, a very rare thing in what is usually a toxic swamp
Thank Alex I to have a shop vac system that I have 2" pvc pipe that is run through my shop. Mine isn't as long as yours but I was wondering if the 2" was going to be good enough now thanks to your video I know it will be
Nice video! Glad the proof is out there that this can be done. Thanks!
This gave me a clear idea on how to run my pipes, and what to use.
I pretty much have the same set-up and your right it works just fine and will save a lot of money if you are on a budget like me! Great video and nice shop too!
Hey Tom F! Thanks so much for the comment and I’m glad I set this up this way as well because in the future if I need to upgrade to a larger dust collector, it will just be a matter of switching the vacs out and the piping will remain. For the time being this works great, as I’m sure you know. Thanks for the comment!
Nice setup. I have a very small shop and I have been looking at how to make a similar one for my lathe. Thank you for sharing this.
"I shot the shop-vac, but I did not shoot the dust deputy..."
So random..
but so good.
hahahahahahahahahaha
Thats how im doing mine !! Thanks for the great vid !!!
Great team work
Excellent job!!
I have the same sit up although mine is from habor freight with a 5 gal bucket I am now going to be using the 55 gal thanks for the information it helps many 😊
in the small shop/home media blasting world this is extremely common... in fact most small cabinets come with common size hose ports for this very purpose. Nice set up.
I have a similar setup but am using a FEIN shop vac enclosed in a power vented felt lined box. Only 58 dBa, below speech volume! Great as I use the vac to suction a hand sanding station that is a long and quiet operation. The dust cyclone is a perfect addition as it allows the shop vac to keep it's efficient and filters clean. I did have to use 4 4" duct booster fans ($100) to keep the vac at 36 degrees C.
I built an almost identical system in the UK using 50mm (2") pipe. It works like a charm. I used transparent flexible pipe for the corners so I can see the dust/chippings shoot around the bends. I have a good domestic tub vacuum-cleaner to power it and it is perfectly adequate. ypu need a minimum of 50mm (2") diameter pipe. Any smaller and there will be a tedency for a chip from the router-table to jam in the sytem and then you have the issue of finding where the jam is. Do not be tempted to use a 40mm (1.57") or 1 1/2" pipe. To keep costs down you can make your own blast-gates from high density polyethelene. There are plentry of instructionals on TH-cam on how to do this. You can everything you need on ebay. Good system. Thx for the vid!!
Very nice video; I love how organized everything is. I think a better test of suction is to show sawdust being vacuumed up. You may find that it’s not up to the task of of clearing most of the sawdust from your table saw after that long run. You can always add an inexpensive Harbor Freight dust collector which has more than enough suction.
Great video !!! When I get a chance I will try to set this up for my shop. Looking forward to seeing the wireless or remote option you come up with. Thanks
Phenomenal setup kudos
awesome setup man great video.
very well explained. just found your channel and subscribed due to this great video.thanks
Always have a blast gate open during start-up or you'll burn the motor up on the vac !
Hello Alex, Long term you may find maintenance of your system easier if you put your gate valves on a horizontal or straight out the top so they do not act like dead legs and accumulate dust from other systems in use down stream.
What kind of seal do you have on the garbage can lid, could be getting some loss there?
I have my Dust Deputy mounted to a 33 gal. can also. It works great.
Really good videos, Good tutorial. Thank's !?
Awesome man, I have a lot smaller of space (jealous of the room you have) but I am looking to do the exact same set up you have!! Great video, very in depth and helpful 👍🏼👍🏼
I've been running my shop dust collection system off an old Dyson upright I found on the side of the road for free and a dust deputy on a 40 gallon drum for years.
It works amazing. Debris has never made it as far as the Dyson to need cleaning. Everything ends up in the drum.
Thank you! Great video. You're differently getting thumbs up. 👍 Good job little for helping your old man.
Hey Alex, props on a great job with your piping... Top notch couplers and blast gates. I noticed you had a DeWalt 735 planer. I have one suggestion on that. The 735 has a *very* powerful impeller fan for dust extraction built in. So powerful, in fact, that a) you don't need a separate DC system; and b) even though it has a combo 2-1/2" / 4" adapter, you can actually get shavings blowback using just the 2-1/2". I've found best case is connecting a 4" short rigid flex-hose from the planer port to a 30 micron Dust Right bag that you can put right under your stand. It keeps the planer "happy" (no blowback shavings collecting on the planer bed), and you don't need to run the DC at the same time (easier on the ears if you're doing lots of planing). But, thumbs up on your setup and equipment... Great video. Wish I had that much space as well...
Dewalt sells a kit that connects to a 32 gallon trash can and works pretty well except that the strings that tighten the shroud is a little difficult to use.
I have a power bar that's made for this type of setup. When you turn on any tool that's plugged into it, there's a slight delay and then the vacuum turns on too.
Very Nice setup. Great video
For me, I have found it is good for small dust volume tools, but much prefer the higher collection that my big dust collector gives me. ie I bought a laguna 14-12 bandsaw and initially just used my shop vac, I had to do a lot more cleanup afterwards as a lot of sawdust was left in the saw. Getting a dust deputy helped keep the suction from reducing over time, but still did not pick up everything from the saw. Once I moved to a laguna pflux 1.5hp, almost no dust is left in the saw. Very cool video, thanks for sharing. :)
Strangely, I have the same shop vac, Dust Deputy and big plastic garbage can as you have. My garbage can kept collapsing so I cobbled a vacuum brake and inserted it atop the Dust Deputy. Now it relieves the vacuum if the line gets plugged for some reason. The makeshift valve "whistles" when the line is plugged that works as a tattle tale also. My garbage can doesn't collapse anymore either.
I use a remote pendant to control my shop vac. I do like your piping system. Thanks.
Good video and thanks for the info. You have a really nice workspace...props
Hey RADCOMJ1! Truly appreciate the comment!! Stick around because we are just getting started!!
Awesome awesome awesome. Great setup
Just subscribed to your channel because this setup is a lot cheaper than I thought. Thanks for the tutorial. ❤
as far as a switch for the vac, you could install a bunch of switches across the room near each piece of equipment and wire them all in parallel.
big thumbs up Alex to you and your son Gabriel, awesome presentation , i am very impressed how good your set up works with a simple vacuum, greetings from the lone star state! subscribed!
Good work ezy setup thank you
Well done sir! Good to know because I was wondering if i did my setup that will be kind of like yours will my shop vac work. I have a little bigger shop vac so it should be all good. Thank you and nice shop!!!
Great video! Little guy is a ham. Doing great Dad!
Great video. Just subscribed. Any chance of a video of you coming up with a way to collect dust from a table saw? Not sure the best route to seal up the back to keep the dust flying out the back
Great video. Good job 👍
This is great! Awesome video. Thanks for doing this. I always felt like single person wood shops don’t need the giant 4 inch dust collection systems.
They help grab more of the dust from around the tools.
The entry lvl 4 in dust collection systems are priced very well now, they work so much better than the SV. If you just running a single machine then nothing wrong with direct connection to a SV
Thank you for sharing your experience with us. Much appreciated. I was wondering if the bucket that that the Dust Deputy is affixed to should be "Air Tight" or not. Don't recall if you had mentioned in the video.
Awesome!!
Very interesting. I hope you have a follow-up video showing the effectiveness when you're using the tools. Thanks for the video.
I'm just a kid but 8 make stuff I used a bauer cyclone separator and a bauer 4 horsepower shopvac
Thanks this helped.
Nice video. FYI, I have the same planer in my shop. That planer puts out much more air volume than the shop vac will pull in. So the net effect is that the seal on the vac will break and dust will spill out. At least that is what happened to my set up using Shop Vac brand 12 gallon vac.
3years late, but.... I had no idea planers put out air. 💀
Does a system like this require grounding against static buildup? Do you get enough suck at the last fitting from the shop-VAC?
Thanks,
Adam
Thank you for sharing Alex.Big like
Of course Marek! Thanks for watching!
Very impressive wood working place.
Hey Alex, great way to showcase the work you've done to improve your shop setup! I actually did a smaller, but similar setup for my garage. I'm using an almost identical sized trash can, and dust deputy, but for some reason my trash can keeps caving in on itself. How did you fix this issue? Thanks!
I had the same issue with my 5 gallon bucket. Try placing your trash can into another trash can. The outer can won't cave in.
Great video. Gotta say, if a shop vac can create enough suction over that much distance, then my plan for a straight line of about 14 feet should work brilliantly!
I have built one of these using a Ridgid shop vac, a 15 gal. used oil drum and a dust deputy. Use it on a daily basis and it works quite well. Only problem I have is with my older Craftsman bet drive table saw it doesn't work the best.
Mark great vid. Keep doing it. If you had placed the bin for the vac vac at the mid point of the system with a blast gate either side the efficiency would be better, just by shutting off half of the system.
That's what I was thinking too.
I wonder if He has considered it if he ever needs to upgrade. I think this is a very good suggestion that would reduce friction loss by 50%.
Thanks for the vid. Just watched a vid. that the "Craftsman" won. Great shop ,great vac. setup. 2 things I might would do. 1st build a little room outside for the vac. / 2nd when ur not using it for the tools have it on as a open air filter something like a 30+30 or even a little smaller for fine particles or staining, paint...Rock on!
Love your set up , would love to see a step by step of another room set up.
Thank you Wyatt Holiday! Thanks for taking the time and commenting!
Alex: you have solved my very lame draw with dust collection, Many thanks. My assumption regarding "shop vac' size is that larger HP would draw even better. I believe you mentioned size at the beginning of the video. [Just checked-right on.] I'm purchasing the Dust Deputy today and hook it up per your instructions. Well done. Great video, and to quote another commenr, "Who needs music?" is appropriate. Thanks, again. John.
The entry level 4in dust collection systems they have now are priced pretty well and there is no comparison they win hands down in a multi machine system. Nothing wrong with using a shop vac directly connected to a single machine works ok.
great video bro, how i wish i could setup like that, but its quite expensive here in our country philippines.
Hi Alex, I know you made this about two years ago, but I just want to add that your system must have MEGA leaks, because that shop vac should have sucked the plastic bag right out of your hand. Without lots of CFM you will not be able to clear the chips from the Planer, Etc. Etc.
Put a rubber gasket between the Deputy and the can lid. Check every blast gate for leaking, find a way to seal everything up. Always have one gate open when you start the Vac... I do not want to be critical but I made my own deputy and use the House Central Vac to power it. No problem using the planer!!!
Nice explanation and layout. I had concerns about how I was going to setup due to the length of pipe. Now, not concerned.
you could also build a sound proof box for the shop vac to limit the noise
Nice work. I’m making a similar one. Did you have to ground it?
Does there need to be a good seal on the trash can? I thought if it had a bad seal it would affect the suction.
Hi thanks. I have a home metal shop what do you think will it work for metal
Hi, great video, very informative 👍.
A couple of questions if I may:
Any issues with or precautions taken for static build up?
The router flexible hose set up, do you think the outlet would work as well if it faced up rather than down toward the bench? I was thinking it might work out better at keeping the hose away from the bench both when in use and when stored.
I noticed you have some pretty rude trolls at the end of the comments. I enjoyed the value of education offered by commenters who know about vacuum systems and, especially, what you offered in this video. I'd suggest that you simply block any users who troll you. Please spare your audience members who want to learn things the agony of having to suffer the vapid troll nonsense by blocking their garbage. Thank you for the video. It helped me, and I appreciate what you're doing to bring us content.
Has anyone suggested grounding your suction pipe and outlets to reduce static and fires? Also you definitely need a key fab remote for your vac. Great job
Great video. I have a small shop and have been wondering how to get an effective dust collection system installed. Now I know. Questions: What is the HP or Amps of the vacuum? I think I've read somewhere to not run the vacuum with all the blast gates closed. Has this ever been a problem for you?
great video - "small shop" :))
What size vac are you running?
Honestly didn't have much faith in the shop vac setup, you have changed my mind on that thanks for the content 👍
Awesome! Did I miss you saying what the horsepower is on your vac? I couldn’t tell. This is exactly what I’m doing right now in my (very tiny) shop! Thanks for the great walk-through!
Great video Alex, I am in the process of setting up the same type of system. I never knew that 2" pipe would be so efficient. The planer chunks may be an issue but like you said you can take the pipes apart if it gets clogged. Take care and waiting for the next one. Al from Maryland
Hi Al! Thanks so much for watching! I’m glad that you enjoyed it! The 2” pipe definitely works well and for the reason of potential clogging, I did not permanently hook the fittings together. Another reason to why my planer is so close to the first portion of the run. I won’t have to undo all the piping if that happens, it will only be a few fittings. Thanks again sir!!
They work best with smaller shop vac for portable collector with less piping and hose. For planer get a vac assisted type and no need for anything but a filter vented sealed bucket which can be under table. I use 5 gallon with garage bags for easy disposal.
For future reference, if you go to the electrical aisle they sell PVC 90 deg. sweeps in grey pipe.
2" diameter and smaller pipe and hoses works best with shop vac type systems while the 4" and larger pipe and hoses are best used with a dedicated dust collector. The main difference between the two is size and static pressure to cubic feet per minute. A dust collector has more cubic feet per minute and works best for larger cavities such as table saws, planers, jointers and any large open dust collection chutes. Shop vac have higher static pressure and works best for smaller openings and individual hand held tools that's constantly moving while tool is in use. For the shop vac an automatic switch control is desirable when using smaller power tools to automatically switch it on and off (DCG product inc. i-socket).
