摘要： According to the invention, a system and method for controlling air flow through the interior of a powder spray booth includes a powder collection system for collecting oversprayed powder from the interior of the spray booth. The powder collection system includes a powder collector with a powder collection chamber, a pulse plenum chamber, and a fan plenum chamber containing a motor driven fan for drawing the air-entrained powder into the fan plenum chamber so that the oversprayed powder is collected on the cartridge filters and filtered air is exhausted from the fan plenum chamber through one or more final filters. A control system automatically adjusts the speed of the motor driven fan in response to pressure changes in the pulse plenum chamber and the fan exhaust chamber so that a substantially constant air flow is maintained through the powder collector.
