ABSTRACT:
A spray booth having bottom, top, and back surfaces and a spray gun for depositing spray coating material onto the articles as they are conveyed through the booth. The bottom surface of the spray booth includes a hopper for collecting undeposited coating material and the top surface of the spray booth includes a vent opening. An exhaust fan is coupled to the vent opening for pulling atmosphere from within the spray booth in a first direction through the vent opening. A baffle is positioned between the spray gun and the vent opening for deflecting undeposited coating material and allowing it to fall by gravity into the hopper, and a filter media is positioned between the baffle and vent opening for collecting any remaining undeposited coating material present before being pulled through the vent opening. A clean air plenum is mounted to the spray booth adjacent the vent opening and houses a high-pressure air source and two venturi tubes for periodically directing a pulse of air through the filter in a second direction to dislodge the collected coating material therefrom and allow it to fall by gravity into the hopper.
