Introduction
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 voltage 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 electrode. The charged fluid is attracted to the grounded workpiece, wrapping around and evenly coating all surfaces.
• 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).
