  • Page 7: 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.

  • Page 8: Gun Overview

    Introduction Gun Overview The electrostatic gun includes the following controls (see F . 1.). • FLUID adjustment valve. Adjusts fluid rod travel. Use only in low flow conditions, to reduce wear. • Fan AIR adjustment valve. Adjusts fan size and shape.
