ABSTRACT:
Improved apparatus for indirectly charging atomized electrically conductive fluids discharged from a spray gun. One or more high voltage electrodes are located outside of the atomized fluid envelope for imparting a charge to the fluid droplets. Air curtains are established to surround insulated electrode holders for preventing a buildup of electrically conductive deposits on the holders. The air curtain is strongest at the end of the holder closest to the atomized paint envelope. The electrodes may be supported from an adapter which permits retrofitting on existing direct charge electrostatic spray guns.
