YAAC - Yet Another Air Cleaner

Because I have such a small shop and no proper dust collector yet (just using a shopvac) I figured I needed some better ways to keep the dust out of my shop. I have seen a handful of different varieties of the air cleaner builds but I specifically like one that was done by RetiredCoastie. I especially liked the joinery to allow the side of it to slide out so you can change filters, service the fan, etc. Slides nicely but fits very snug when it’s completely closed.

I got the squirrel cage fan from an HVAC company who thankfully was throwing out an old furnace the day I went there. I asked if I could buy the fan for a couple bucks but the owner insisted I just take it as he couldn’t justify charging me for an old piece of hardware. Score!! It does have multiple speeds but for now I just wired in the 1 speed until I can track down a good switch. The only one I could find was a small toggle switch with 2 settings but would like to get one with 4 so I can hook up all the leads.

So far I just bought a cheapy furnace filter just so I could get the sizing right but I will be getting some nice filters to make sure it does a good job catching the harmful dust. The dimensions are for a 16×20 furnace filter by 32” long to house the fan and give it a bit of room for the fan to breathe. I think that was the biggest shock to me was seeing how big the fans were. Seeing them in pictures doesn’t do it justice until I starting spec’ing out the dimensions.

I also did a sketchup drawing for this if anyone is interested in building this particular version.

It is a very good design. For a dust collector, you might consider building one of those boxes just for that(hose input vs. filter input). Many HVAC blowers can exceed 1000cfm which is good for a small dust collection system.

—Then you can have a shop that really sucks :)

Great looking air cleaner. I would love a copy of the sketchup plans if you don’t mind.

Hey Don,

Yeah, I’ve definitely thought about that but when I did my research unfortunately it’s a different type of fan that would be required to build a dust collector. Dust collectors have the impeller as opposed to a squirrel cage fan having a different sort of enclosure to move air. Plus, when I get a bigger shop (in the next year or so) I’m going to bite the bullet and go with a 2HP collector, wire up the 220V and just be done with it. I love my DIY solutions but for that I think I’m just going to stick with a commercial unit.

Nice filtration system. Has been on my list of things to do for a while now as I am currently just using the Shop Vac and a simple house fan with filter bungeed to the front. Grats on getting the free squirrel cage :) Is this staying on the table or are you mounting it to the ceiling? Thanks for sharing…

Hey Dan,

Yeah it will be mounted on the ceiling in the middle of my shop. Between the fan and the wood, that thing weighs a ton and I’m not going to be asking my wife to help me mount that to the ceiling. It’ll either end in divorce or a very serious accident so I’ll wait until a friend comes over to help me get it mounted. =)

Very similar to one I have used for years. Nice work.
The difference is I built mine into a floor cabinet with wheels so I can move it around the shop. I also have a sharpening station on the top and some storage areas. It mainly sets next to my wood stove so that it circulates the heat while it clears the air.

Very nice. This is one of those things where you say “I really need to build one of these” every time you see one. I’m very thankful for all the pictures you included. I keep hounding my HVAC company for any throw away blowers. That’s my last hurdle. Thank you!

Very nicely done. Glad I could be of assistance and enjoy the cleaner air that this filter will provide.

Very nice set up or the air filtration system. I am new to the site and was wondering if it is not too late could I possibly get aopy of the plans for this?
