Overview
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 external charging probe.
The pump supplies fluid to the hose and gun, where the
fluid is atomized by the air cap and the atomized parti-
cles are electrostatically charged as they pass the
external charging probe. The charged fluid is attracted
to the grounded workpiece, wrapping around and
evenly coating all surfaces. The external charging
allows the fluid supply to remain grounded at all times
and therefore eliminate the need for an isolation sys-
tem.
