Abstract
In an electrostatic powder spray gun, a cylindrical air curtain is formed toward the front side of a gun main body by supplying compressed air to an air chamber formed between the outer peripheral surface of a cover member and an outer cylinder so as to eject the air from an air blowing opening. Owing to the air curtain, powder particles move toward an object to be coated without the risk of scattering to an ion trap electrode.
