GENERAL DESCRIPTION
GM2000 EAC SPRAY GUN
The GM2000 EAC Electrostatic Air Coat Spraygun is
very light and easy to service. It can be used up to a
maximum operating pressure of 3625 PSI.
Trigger Lock: Turn knob clockwise to lock the trigger.
Electrostatic On/Off Switch: This switch can be used to turn
off the electrostatics. Sometimes the Faraday Cage effect
prevents proper coverage on inside corners. If you run into
this problem turn this switch off (up), spray the inside
corner(s), then turn the switch back on (down), and resume
electrostatic spraying.
Fluid Inlet: Securely fasten airless hose to this threaded
port. Be sure to use only hose with adequate pressure
rating.
Air Inlet: Securely fasten air hose to this threaded port.
Air Adjustment: This knob can be used to regulate the
amount of air that is used in spraying. Turn knob clockwise
until it closes, slowly turn knob counterclockwise until ade-
quate air flow results.

VM 200 ELECTROSTATIC POWER PACK
The heavy metal case is water tight. All external compo-
nents and operating controls, as well as the case finish are
largely solvent-resistant.
With the power switch on, the green pilot lamp lights up.
Internal components now convert the supplied voltage into
a pulsating DC voltage of 12 V and 17 kHz frequency. This
low output voltage supplies the GM 2000 EAC gun via the
connecting cable.
When the gun trigger is pulled, a solenoid-operated Reed
contact initiates the switching on of the high voltage, signal-
led by lighting up of the red high voltage lamp. Via the
connecting cable to the gun, the 12 V/17 kHz, medium-
frequency, low voltage is now fed to the high-voltage
generating section inside the guard of the gun. Here, a
transformer within the cascade converts the low voltage into
a high voltage of 80 kV and applies this with negative
polarity to the electrodes.
