How to build a Shop Air Cleaner and Paint Booth Ventilation System

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.

[@davidreynolds4684]

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?

[@scottgordin9709]

This dude is a genius, that is an awesome idea. I really like the air diverting idea, mind blowing.

[@rpvitiello]

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…

[@nikbivation]

love the way you narrate and describe things!

[@705techno]

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.

[@TommyTompkins]

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.

[@TheNyhm1]

When spraying solvent based finishes you should use an explosion proof fan. You’re taking a very dangerous risk

[@CT-vm4gf]

This is the best shop air cleaner build I’ve seen so far on KZbin. I like that you used a powerful blower and not something like a box fan.

[@TommyTompkins]

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.

[@grzejnikMilosz]

​@@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.

[@jamesitube]

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.

[@bruinflight1]

Hey, question though: does that Reznor heater take... 9-inch nails??? Eh??? EH??? ^_^ Love this build! Great job!

[@TommyTompkins]

lol!!!

[@mengvaj87]

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.

[@TommyTompkins]

Do you have a picture or a link to the one that you used? Any idea what the CFM rating is?

[@alainprefontaine1909]

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

[@grzejnikMilosz]

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

[@jerrysgaragethemoneypit2028]

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!

[@frrapp2366]

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

[@stevesloan6775]

wow first time Ive seen that router with a bearing....Awesome

[@TommyTompkins]

It works great!

[@pete8279]

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.

[@TommyTompkins]

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.

[@pete8279]

@@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.

[@paulmanhart4481]

Can you tell me more about the fan? 120 volts? HP? CFM? Output diameter? Thanks, Paul

[@TommyTompkins]

Yeah it's 120 volts but honestly, I don't know much else about it. It was a Craigslist find.

[@ronmedere9631]

I thought for any fan exhausting paint and possible solvents should be a fire or explosion proof motor as a safety precaution?

[@TheBCninja]

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.

[@davidreynolds4684]

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.

[@Khoruzhin]

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.

[@TommyTompkins]

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.

[@mnwoodworker7795]

[@MrFisseha50]

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.

[@TommyTompkins]

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.

[@kennethbubser9601]

Great job. But need more intake air. 8 inch intake not enough

[@spirituallyinsane]

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.

[@bill-chichi9701]

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.

[@plasticbuzzardmodelshop9715]

Interesting design.

[@Ton369]

Question: Why do you filter and vent the air? Why not just vent the air?

[@TommyTompkins]

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.

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.

⚠️ caution: The negative air pressure created from exhaust fans can overpower the gas appliances (especially natural draft ones) and they can in turn spill carbon monoxide in your living spaces. Make sure you don’t have natural draft appliances in these affected spaces, can bring in at least the equivalent amount (formulas involved) of fresh air while exhausting.

[@TommyTompkins]

Good point. I usually crack my garage door which brings in fresh air when painting. When it's just filtering the air, there's no need since it doesn't exhaust out of the shop.

[@jacobframe8769]

Nice work. I would kindly point out that when using it as an air extraction unit be careful that your heater is not on. It could cause issues as it was not designed to work in such a negative pressure environment.

[@TommyTompkins]

What types of issues could I potentially experience? Just curious. I've been using this for about 1.5 years now and haven't had any issues with the furnace that I know of. But I should mention that I use it in extraction mode much more during the summer months to draw in some dry air conditioned air from the house and pump out the hot humid air for some climate control. When I do this, I also turn on the air exchanger in the house thinking that it might help with the negative pressure. The only time I do this in the winter is when I'm painting which isn't that often.

[@jacobframe8769]

@@TommyTompkins it can cause the pilot to go out or even the furnace itself while it is running. The furnace was designed to use the air in the room for combustion but when the room is at a negative pressure it could back draft the exhaust into the garage instead of out of the flue.

[@joelromero5346]

Just noticed your Reznor garage heater, is there any danger using that when you spray?

[@TommyTompkins]

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."

[@TheFreshRinse]

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?

[@TommyTompkins]

I filter the air to the outdoors to help protect the environment. LOL! Kidding...The filters are only used when the insert is used to recirculate the air in the room to help filter out the fine airborne sawdust particulate. When the other insert is used, the blower funnels the air to the outside. In that case filters aren't necessary. But when using the spray booth, it still helps to have some filters to prevent paint from caking up the fan blades and because I don't want to paint the siding on the outside wall of the garage.

[@riakata]

Be careful to regularly maintain the blower assembly if the bearing fails or anything rubs inside the housing you risk starting a fire or explosion when spray painting. For spray painting it is better to use positive pressure so nothing about the fan is in the air stream but if your doing a negative pressure setup you should be using a blower with an aluminum wheel so that it is spark resistant.

[@TommyTompkins]

Good point. The bearings in this unit are brand new and were replaced prior to building this. But I hear what you're saying and it's a good idea to maintain the bearings and blower assembly if anyone does choose to go this route.

[@natepierce1281]

Great video, Did you do anything for a fresh air inlet to offset the air you are removing from the shop?

[@TommyTompkins]

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.

[@Hurbace]

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.
