Gun Overview Gun Overview How the Electrostatic Spray Gun Works The air hose supplies air to the spray gun. Part of the air operates the alternator turbine and the rest of the air atomizes the fluid being sprayed. The alternator generates power, which is converted by the power cartridge to supply high voltage to the gun’s electrode. 3A2494D The pump supplies fluid to the fluid hose and gun, where the fluid is electrostatically charged as it passes the electrode.
Gun Overview Controls, Indicators, and Components The electrostatic gun includes the following controls, indicators, and components (see Fig. 1).
