Abstract:
A rotary spray atomizer for applying electrically conductive paint to surfaces, comprising:a housing having a front and a longitudinal axis; a spray head fitted on said front of said housing for receiving a supply of paint and discharging the supply of paint in a spray mist as a result of rotation; a drive motor disposed in said housing for rotary actuation of said spray head; at least two electrode holders disposed along a concentric circle, having an end, and extended towards said front parallel to said longitudinal axis of said housing; at least two electrodes each accommodated in and protruding from said end of a respective one of said at least two electrode holders; and at least two cascaded high-voltage sources each built into a respective one of said at least two electrode holders for receiving a low-voltage current, feeding a respective one of said at least two electrodes and causing said at least two electrodes to generate an electric field applying the spray mist discharged by said spray head to an application surface.
