GENERAL DESCRIPTION
The Vector Solo TM AA90 Applicators are a com-
bined air/airless powered only by a pressurized
air source. Pressurized air creates rotation of a
turbine generator that powers a cascade. The
cascade generates a high voltage DC charge
to the electrode creating an electrostatic field
between the atomizer and the target. The target
is electrically grounded through its support which
may be either stationary or moving.
A regulated pressure fluid system delivers coating
material to the atomizer. At the time of triggering
the applicator, fan and atomization air is introduced,
which atomizes the coating material into a spray
mist. The atomized spray particles under the influ-
ence of the electrostatic field become electrically
charged. 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 Solo 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 releas-
ing sufficient electrical or thermal energy during
normal operating conditions to cause ignition of
specific hazardous materials in their most easily
ignited concentrations in air.
As the applicator electrode approaches ground,
applicator circuitry causes the high voltage to
approach zero while the current approaches its
maximum value.
