ABSTRACT:
A rotary atomizer includes an inside surface onto which a coating material is deposited, an opposite outside surface and a discharge zone adjacent the rotary atomizer's inside and outside surfaces, coating material being discharged from the discharge zone. A housing substantially surrounds and houses the rotary atomizer except for a region of the rotary atomizer adjacent and including the discharge zone. The housing includes an inside surface, an outside surface and an opening adjacent the inside and outside surfaces of the housing. The inside surface of the housing and the outside surface of the rotary atomizer are treated so as to render them electrically non-insulative. An electrostatic potential difference maintained across the electrically non-insulative inside surface of the housing and an article to be coated by material atomized by the rotary atomizer causes charge to be transferred from the electrically non-insulative inside surface of the housing to the outside surface of the atomizer.
