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.
