Bryan's Dust Collector

CLEARING THE AIR
A trip to the salvage yard yields a bonanza.

SHOP OWNER: Bryan Cowing
LOCATION: Woodstock, Ontario, Canada

    Recently, I built my own airborne dust collector. I picked up a 4-speed fan from the scrap metal yard for $5.00. Using 2x4 material ripped into 2x2, I made a top and bottom frame. For the outer panels, I used 7/16 plywood. I sized the openings on the sides for 16x25 filters.

    The end panels are 7/16" plywood, screwed to the top and bottom sections. A middle support keeps the filters from blowing into the main compartment.

    I had sheet metal bent to hold doubled up filters. I use a 3M Filtrete and a low cost pleated filter as a pre-filter on each side.

    To utilize three of the four speeds of the fan, I used two 3-way switches and a pull chain switch for on - off. The pull chain switch mounts in the back bottom of a double electrical box and the chain passes through a 1/2" hole in the bottom of the box.

    I hung the unit with chains from the shop ceiling. My total cost to build this unit was about $100, with $60 going for the filters.
