ABSTRACT:
A powder feeder for supplying particulate powder material to powder applicators mounted in a powder spray booth comprises a housing having an inlet connected to the powder recovery system of the powder spray booth, and an outlet. A fluidizing plate and pump or rotating screw feeder is mounted within the interior of the housing to aid in the discharge of particulate powder material through the outlet of the housing to the powder applicators in the spray booth. A clean air chamber mounted to the housing is formed with an inlet communicating with the housing interior and an outlet located outside of the housing which is connected to a source of vacumm. The vacumm source creates a negative pressure within the clean air chamber to draw air from the housing interior to vent its interior. A cartridge filter is mounted within the housing to the inlet of the clean air chamber to prevent airborne particulate powder material from exiting the housing in the course of venting thereof. The cartridge filter is automatically cleaned of collected particulate powder material by a blow back device mounted in the clean air chamber.
