I have been admiring the brand name air cleaners at the local woodworking store and those built by other lumberjocks for quite some time. About a month ago, there was a craigslist posting offering a squirrel cage blower and motor that was used to dry basement floors. I checked it out and found two blower fans, only one had a working 1/3hp motor. The guy gave my both for the price of one $20. I combined parts of both to get the blower and motor combo pictured.
The cleaner is built from 1/2 plywood leftover from other projects. I used three 15×20x1 furnace filters, 2 on the intake one of the out. Two filters are 3M pleated good ones and the initial is a cheap fiber glass one.
The overall dimensions are 21×21x25. The unit hangs from J-bolts and hooks from the ceiling connected by chain leftover from a new dining room light I installed awhile back. I used a 60 minute timer and wired it to have a plug end as I will likely move my shop from time to time and want the ability to relocate the cleaner easily. The total cost was under $50!
I will admit that it is a little louder than I would like. I can’t hear my shop radio easily while it runs, but I usually wear ear protection that has a radio built into it so this is not much of an issue. The unit is much quieter than any of my power tools when they are running, and for the price I can’t complain. I have a few projects to start this weekend and will give it its initial workout.
If you are thinking of building one of these, DO IT! Its an easy build and you can get blowers cheap. Before getting my unit, I called around to some HVAC guys. They got back to me after I had already scored the two blowers so I didn’t need them, but they only wanted $25 for a 110 multi-speed unit.
