Abstract
A rotary spray atomizer for applying electrically conductive paint, in particular water-based paint, to surfaces, includes a housing. A spray head is fitted on front of the housing for receiving a supply of paint and discharging the supply of paint in a spray mist as a result of rotation. A motor is disposed in the housing for rotary actuation of the spray head. At least two electrode holders are disposed along a concentric circle and extend towards the front parallel to a longitudinal axis of the housing. Electrodes are each accommodated in and protrude from an end of a respective one of the electrode holders. High-voltage sources constructed as a cascade are each plugged into a respective one of the electrode holders for receiving a low-voltage current, feeding one of the electrodes and causing the electrode to generate an electric field applying the spray mist discharged by the spray head to an application surface.
