The air hose supplies air to the spray gun. Part of the
air operates the alternator turbine and the rest of the
air atomizes the fluid being sprayed.
The alternator generates power, which is converted
by the power cartridge to supply high voltage to the
gun’s electrode.
The pump supplies fluid to the fluid 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.

When connected to a voltage isolation system,
all of the fluid in the spray gun, fluid hose, and
isolated fluid supply is charged to high voltage,
which means that the system has more electrical
energy than a solvent-based system. Therefore,
only non-flammable fluids (as defined under
) can be sprayed with the gun or be
used to clean, flush, or purge the gun.
Precautions must be taken when using electrostatic
waterborne equipment to avoid potential shock
hazards. When the spray gun charges the isolated
fluid to high voltage, it is similar to charging a
capacitor or a battery.
The system will store some of the energy while
spraying and retain some of that energy after the
spray gun is shut off. Because it takes some time
for that stored energy to discharge, it is important
to read the instructions, including the
Discharge and Grounding Procedure, page 33
, and
, to understand when you can
approach or touch the gun nozzle.
The amount of time it takes to discharge the
energy depends on the system design. Follow the
Fluid Voltage Discharge and Grounding Procedure,
page 33
, before approaching the front of the gun.
