This is a combined air/airless method for
electrostatically applying coatings to objects. The
Vector AA90

Vector AA90 Vector AA90
Vector AA90 system applies a high voltage DC
charge to the applicator electrode, creating an
electrostatic field between the electrode and the
grounded target. The target is electrically grounded
through its support which may be either stationary
or moving.
A regulated high pressure fluid system delivers
coating material to the fluid nozzle and is atomized
by passing through an orifice under pressure. The
atomized spray particles become electrically
charged under the influence of the electrostatic
field surrounding the nozzle. The air supply to the
applicator aids in shaping the coating material into
a desired pattern. The charged particles are
attracted to and deposited on the target object.
The forces between the charged particles and the
grounded target are sufficient to turn most normal
overspray around and deposit it on the back
surface of the target. Therefore, a high percentage
of the coating is deposited on the target.
One of the many features of the Vector AA90
applicator system is that the electrical energy,
which is available from the resistive charging
electrode, is limited to the optimum level of safety
and efficiency. The system is incapable of releasing
sufficient electrical or thermal energy during normal
operating conditions to cause ignition of specific
hazardous materials in their most easily ignited
concentrations in air
.
The power supply provides voltage output to the
applicator and contains controls for AC on/off,
high voltage adjust, "one touch" triple setpoint, and
displays kV and
μ A in real time.

When more than one waterborne
applicator is fed from a common isolated
fluid supply, there is a potential for electri-
cal energy discharge through any other
applicators when one applicator is trig-
gered. Depending upon the system
capacity, this discharge could be hazard-
ous. Install only one spray applicator per
isolated fluid supply system.

As the applicator electrode approaches ground,
the power supply and applicator circuitry cause
the high voltage to approach zero while the current
approaches its maximum value.
