Downdraft Table for Sanding and Powder Coating

George CarlsonNews

A new Downdraft Sanding Table was built in The MakerBarn.  The table has a large squirrel-cage blower from a 5 ton whole-house air conditioning/heating unit.  The blower pulls air down through the table top, filters the air with a two-stage filter, and blows it back into the room.   The unit moves a lot of air, and can be used for cleaning the air in the finishing room while using the stationary sanders.  The hood allows the unit to also serve as a powder-coating spray booth.

The unit is 60″ wide, 30″ deep, and 65″ high.  It was built using pre-finished birch plywood.  This is the same type of material used by cabinet makers for internal shelves on kitchen cabinets.  It has a tough epoxy finish that is easy to keep clean. The table top is a grid made from the same plywood.  There were over 400 dado cuts made to produce the egg-crate style grid.  A four foot LED lighting fixture makes the booth bright and easy to work with.  The entire unit was designed and constructed in The MakerBarn.
