Abstract
An apparatus for use in directing a flow of air with particles entrained therein toward a workpiece includes a nozzle and a deflector. The nozzle has a passage with a noncircular cross sectional configuration. The deflector has an outer side surface with a circular cross sectional configuration. A flow of air with particles of powder entrained therein is conducted along outer surface areas on the deflector at a first volumetric flow rate. A flow of air with particles of powder entrained therein is conducted along outer surface areas on the deflector at a second volumetric flow rate which is greater than the first flow rate. The deflector includes a porous member which is releasably connected with a main portion of the deflector to facilitate cleaning and provide access to the interior of the deflector. Seal members are provided between an electrode sheet, the porous member, and the main portion of the deflector.
