Exhaust Fan

Make 18, Week 9

My workshop has an exterior door and a doorway going into the garage. When making dust, I open the outside door and car garage door for some ventilation. The doorway into the garage and the outside door and in-line, so the rest of the shop doesn’t seem to get a lot of air movement. A forced air exhaust vent at the other end of the shop seems a good idea.

The other thing I’ve been thinking about is I probably don’t want to have all the doors open when the weather turns cold. ┬áMy thinking is that I may run the fan only when running saws, or perhaps just flip on the fan for a few minutes to clear out the air. There’s no heat in the workshop, but I’m thinking of installing some kind of electric heat. By just running the fan to suck out dust, I’m wondering if I’ll be able to take the edge of the cold in the workshop and momentarily run the fan to clear out the air. I plan to crack the garage door when running the fan in the winter.

I’ve also moved my shop vac dust collector over by this fan. I run a short hose from the blower port on the fan and shoot that out the fan. The idea is whatever isn’t captured by the Dusty Deputy and HEPA filter should go side.

Anyway, I got this 14-inch fan from Amazon. There are bigger fans, but they seemed excessive and not worth the price for my space. I didn’t get fussy installing it. I basically cut out a hole in the garage wall with a beat up jigsaw blade, then braced the fan with 2×4 boards against the joists. I wired then it up using an extension cord. Eventually, I’ll make it more permanent with a switch.

This seems to work pretty well. There’s noticeable less dust hanging in the air and even less eventually settling. I always wear a respirator when making dust, but I feel this fan clears the air enough to remove the mask when not running saws or sanders.
