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 (down), spray the inside corner(s), then turn
the switch back on (up), 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 adequate air ow results.

VM 200 Electrostatic Power Pack
The heavy metal case is water tight. All external components and
operating controls, as well as the case nish 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, signalled 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.
