Abstract
A coating powder feed device supplies a plurality of flows of coating powder from a container to, for example, a plurality of powder coating devices or a plurality of containers. A plurality of individual powder feed devices are mounted in a housing which is sealed against entry of coating powder. Only the exterior housing surfaces, intake heads at lower ends of the individual powder feed devices which include powder suction inlets, and the internal fluidized powder flow channels are exposed to the coating powder, thus facilitating cleaning when changing powders. The individual powder feed devices are simultaneously lowered into a powder supply container during use.
