A rotating powder bell cup electrostatic spray assembly is provided. This assembly includes a bell cup body removably mated coaxially by screw threads to a first deflector, the assembly rotatably affixed to an air powder supply. Preferably, the bell cup and first deflector are constructed from an insulative, non-stick material. The assembly includes unique, streamlined, preferably teardrop shaped, paddle deflectors. All corners around which powder passes are rounded, thereby achieving streamlined flow and little or no powder accumulation, as well as improved efficiency, ease of assembly and disassembly, and ease of cleaning for such devices. A preferred non-stick material of construction of the bell cup and first deflector is polytetrafluoroethylene.
