Since my shop is in my basement, I decided to try to minimize the dust problem created by using tools that really didn’t come with all the dust management features of the newer stuff. I noticed that besides the obvious sawdust, everything in my basement was developing a layer of fine wood dust that had settled out of the air..
I went to a couple of furnace installers, and discovered that when they put in a new furnace for someone, they often just toss out the old one, and I obtained a furnace blower motor and “squirrel cage” fan from just such a unit for free if I simply took it out myself…which I did. Next, I was trying to design a proper “box” for it, when I came across some old kitchen type cabinets (actually from an old dental lab) that I added to my shop for storage. I had an extra, and as the pics show, it was just the ticket. I used the logic that air in equals air out for my vent area. The air is drawn in through the lower vents, goes through the filter, and blows out of the one on top. When not in use, I have a piece of counter top that I put on top so I can set junk on it if I need to.
The reason for the drawer was that my original idea was to add a hose port to suck sawdust away from tools and collect in the drawer but I don’t get enough suction with the fan motor to pull particulates, but the drawer was there anyway, so no great loss. Maybe I’ll experiment with adding and old shop vac motor in the future.
The pics should be self explanatory. The motor was actually a 3 speed that I use on low and it really moves a lot of air and is quiet, too.
As a test, I used an air gun/compressor and blew all the dust off my shop area into the air and turned the unit on. After about 15 minutes, I had clean air and a dirty furnace filter in the unit.
Since I got the fan and the old cabinet for nothing, and had the casters (casters are a must) my only cost was the vents, so I’m a happy guy. -SST
