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.
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.
Gun Overview
The electrostatic gun includes the following controls
(see F
IG. 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.
• 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 (standard gun only). Green when
ES is ON (I).
• Voltage/current DISPLAY (smart models only).
Shows voltage (V) and current (A). Green=spray,
yellow/red=see Troubleshooting, page 23.
• ES HI/LO switch (smart models only). Sets volt-
age to HI or LO (factory settings).
• LO VOLTAGE adjustment (smart models only).
Remove plug to adjust to four settings.
