ABSTRACT:
A powder coating system particularly adapted for coating large objects such as automotive and other vehicle bodies comprises a spray booth having a manual/robotic spraying area for the application of powder to the inner door flanges and other hard to reach areas of the vehicle body using manually or rotatably operated powder dispensers, and an automatic spraying area wherein the remainder of the vehicle body is coated using automatically manipulated powder dispensers. A powder collection and recovery system is associated with the spray booth which includes removable cartridge filters arranged in V-shaped filter banks within powder collection chambers beneath the floor of the booth, a system for the transfer of powder collected in the powder collection chambers to hoppers located exteriorly of the booth and an air exhaust system for equalizing the negative pressure within clean air chambers which receive clean air after filtering by the cartridge filters.
