ABSTRACT:
A powder delivery apparatus for use in a paint supply system. The apparatus has a flexible inner hose having an innermost and outermost surface with pores extending therebetween. The innermost surface defines a channel along which powder particles may flow. Surrounding and extending coaxially with the inner hose is a flexible outer hose. The innermost surface of the flexible outer hose and the outermost surface of the inner hose define an annular path that is charged with air. The air is forced under pressure radially inwardly through the pores to the inner hose so that during powder flow, powder particles are atomized and prevented from fusing to the innermost surface of the inner hose. Thus, powder build-up and impact fusion are avoided in the inner hose. Accordingly, consistent powder flow rates and supply pressures are promoted.
