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?
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…
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
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.
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.
*Hello there, I have requested your DVDs, for simpler and quicker approach to manufacture a shed **Allmy.Tips** I trust the substance are as you guaranteed it will be. Just I'm worried with the substance, it won't be anything but difficult to settle on a decision from the various plans.*
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.
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.
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 🤘🏼
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.
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!
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.
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!
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.
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
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.
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.
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.
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!
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 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'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.
Guys can someone please tell me how to add in all the parts into sketch up? I always watch these videos and they have somehow imported the chop saw or like here the filters to the application. Can somemone please shoot me a video or hit me up on how to do this?
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.
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
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.
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.
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
@@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).
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.
⚠️ 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.
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.
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.
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."
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
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.
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.
Hello again, I'm finally in a position to build this device, and I didn't know if your instructions include the specs for the centrifugal blower you used. I'm trying to source my own at the moment and want to know how big I need to go. Thanks!
Hello Devin - I didn't include any specs for the blower other than the size of the blower that I used in my specific application. Here's the text copied directly from my plans: "Step 2: Measure the Blower The blower housing is going to fit inside of the Main Enclosure so before you start cutting wood, you need to make sure it’s going to fit within the default measurements. These 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 these 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)."
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.
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.
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

Tunbridge Wells is a great place
When spraying solvent based finishes you should use an explosion proof fan. You’re taking a very dangerous risk
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.
Smart build
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.
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.

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.
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.
Great job and video, Tommy! I will likely order and adapt your plans for a farm truck and equipment paint shop.
That is badass
In a typical ac motor like that there aren't any brushes where sparks occur. No ignition possible.
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."
Great job! Makes sense.
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.
You should make a box to cover the motor
What were the "cheap" blue fiberglass filters you got instead ? (brand) Thanks !
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
wait, why would you need filters if you recycle the air out from the room?
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.
@@TommyTompkins all makes sence, thanks , ill subscribe,
Awesome work
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.
Hello again, I'm finally in a position to build this device, and I didn't know if your instructions include the specs for the centrifugal blower you used. I'm trying to source my own at the moment and want to know how big I need to go. Thanks!
Hello Devin - I didn't include any specs for the blower other than the size of the blower that I used in my specific application. Here's the text copied directly from my plans:
"Step 2: Measure the Blower
The blower housing is going to fit inside of the Main Enclosure so before you start cutting wood, you need to make sure it’s going to fit within the default measurements. These 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 these 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)."
Hi Tommy, I am from Viet Nam. please advise what software for your design. Thanks Tommy
Hello - I use Sketchup
Great project! Thanks for sharing!
Nice❤
Love it!
Thanks!
Nice job! Although, how about just hanging it with chains, eye bolts, and carabiners? Just a thought.
The handsaw didn’t do a really nice job with the cut.......you did. Excellent
Thanks!
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.
How much did you spend ?
I think I spent around $300 total. But I ended up with a much more functional machine compared to any store bought equivalent.
Tommy Tompkins thanks!
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.
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
