Neighbor got a new A/C system and put air handler on the curb. One mans junk…. Double filters on each end. Expensive filters on inside,cheap ones on outside to catch the big stuff. I had it on wheels but would blow across the shop as it moves tons of air. I now have it hanging from ceiling near heater. It exchanges air in the shop quickly.
I also installed a 3 speed rotary switch to lower the speed. 4 filters and 1 sheet of plywood invested.

P.S.
I have since removed the supply grate as I found it was too restrictive and added a deflector to direct the jet blast down.

Very nice! Low flying birds beware, that thing looks like it could pull down a small plane. Good news for your lungs and anything you are finishing.

Nice job. I’m building one now and I don’t notice much of a difference in speed between high and low. What brand of switch did you use. Thanks for posting.

I don’t know what brand it was got it at hardware store. I dont notice much difference either. I think its like 2-300 rpm difference in each position. I use it on low most of the time for general scrubbing and high when I’m sanding.
