Abstract: A powder spraying gun generates a desired pattern of electrostatically charged particles for coating a workpiece without rotating parts or particle deflectors. The powder pattern is generated with a funnel-shaped output in conjunction with air introduced into a powder charging chamer of the gun in a tangential swirling motion. The swirling air is additionally used to purge agglomerated powder particles from the charging electrodes in the charging chamber. The charging chamber surface is fashioned from material exhibiting low friction or high resistance to powder impact fusion.

Abstract: A powder paint color changer features a single cleaning fluid port at one end of the color changer manifold (106) for direction of cleaning fluid, such as pressurized air, through the main output interior chamber of the color changer manifold thence through a supply hose (103) which is adapted for coupling to a paint application device (102). Additionally, the powder paint color changer manifold includes a replaceable insert of impact fusion resistant material which defines the surface of the manifold's interior cavity.
