Introduction

How the Electrostatic 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.

The pump supplies fluid to the hose and gun, where the fluid is electrostatically charged as it passes the elec- trode. The charged fluid is attracted to the grounded workpiece, wrapping around and evenly coating all sur- faces.

•Atomizing air RESTRICTOR valve. Restricts atomizing air flow. Replace with plug (included) if desired.

•ES ON/OFF valve. Turns electrostatics ON (I) or OFF (0).

•ES INDICATOR. Green when ES is ON (I).

Gun Overview

The electrostatic gun includes the following controls (see FIG. 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.
