Page 6: Introduction
Introduction Introduction How the Electrostatic Air Spray Gun Works The air hose supplies air to the spray gun. Part of the air operates the turbine and the rest of the air atomizes the fluid being sprayed. The turbine generates power, which is converted by the power cartridge to supply high volt- age current to the gun’s electrode. -
