Low-Cost Air Cleaner For Shop

Low-Cost Air Cleaner For Shop FARM SHOP Miscellaneous 28-3-36 Ben Kambeitz, Box 23027, Medicine Hat, Alberta, Canada T1B 4C7: "By making use of an old furnace fan and a pair of used tractor air filters, I was able to come up with a low-cost air cleaner for my shop. It's a low-cost method of removing particles from the air inside a closed shop. The assembly mounts on the ceiling. The fan mounts on an L-shaped metal bracket that's fastened to the ceiling and is operated by a 1/4 hp electric motor. The filters mount below the fan and are turned upside down so the large opening is on top. The filters collect dust and even take the smoke caused by welding out of the air. The charcoal filters out the paint smell from auto painting as well as the mist. It works great. When the filters get dirty I simply throw them away and install two more used ones. I get the filters at our local dump and use a compressor to blow the dust out of them. "The filters fit onto a pair of holes cut from plywood into the bottom part of the bracket. To attach the filters to the fan, I ran a length of redi rod through a pipe that runs vertically inside each filter. The pipe keeps the charcoal from falling out the bottom. The flanges on top of the filter were bent over to fit onto the fan. To change filters I just unscrew the filter from the flange."
