Been wanting to build one of these for a long time, as I’ve been getting really tired of all the dust that floats around the shop. Found a deal on a small (250cfm) blower and decided to give it a shot. I used standard 12×24x1 furnace filters for this; two filters on the intake side, and one filter on the exhaust side. Was easy to throw together using some “extra” 1/2 ply I had left over. I plan to hang it from the cieiling and will be looking for some type of wireless remote that I can use to turn it on and off, or maybe a timer to turn it off. Either way, I had fun building it, and it the blower turns out to be too small I can always go find a bigger one.

Might want to put your wire connections inside a junction box. I like the idea.

I got the blower from Surplus Center. I did think about a junction box, but switched out the standard wire nuts with silicon in them to keep the dust out.

Having used this for almost a year; it has worked great and has made a significant difference in the amount of dust in the shop!
