This is the air filtration system that I built last year for my workshop. The squirrel cage blower came from a downdraft stove we replaced when remoding our kitchen. Didn’t realize that I would be using it for air filtration when I pulled it from the stove, just knew it would come in handly at some point. Glad I saved it now.
The box is made from 3/4” ply that I had left from another project. Everthing was butt jointed using glue and sheet rock screws. I tried to keep the size as small as I could and still fit the blower motor inside. I ended up using 12×20 filters which kept the heigth of the box to 12 inches. (filters ar not a true 12 inches high.) The length of the box ended up being 24 ” long and the width 22”. The exhaust end of the box was fitted with a 8”x16” heat and air vent. The box is still unfinished but I may eventually get around to painting the box but didn’t seem important at the time.
Currently I have the two speed motor wired for a single speed but plan to change that when I install the additional work light to the bottom of the air box. At that time I plan to put in a a triple gang switch for the two speed motor and the light. I currently turn the filter system on via a remote control that also control dust collection and my shop vac. Will post something on that later.
My total investment in the air filtration system is about $15 for the air vent and filters. Everything else I used was lying around the shop looking for a project, lol
