ABSTRACT:
A powder barrier with a filter element of microporous material for use with an air injector in a powder feeder in a powder coating system. The microporous material is permeable to air, but not to the coating powder. The powder barrier prevents a penetration of coating powder into the air feed path in a direction opposite to the air flow direction. The powder barrier permits a quick color change without the need to disassemble the air injector for cleaning.
