GENERAL DESCRIPTION
The
Vector
Solo
TM
Waterborne
is an air atom-
izing applicator 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.
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 ap-
plicator system is that the electrical energy, which
is available from the resistive charging electrode,
is limited to the optimum level of safety and ef-
ficiency. 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.
As the applicator electrode approaches ground,
applicator circuitry causes the high voltage to
approach zero while the current approaches its
maximum value.
The Vector Solo Waterborne is designed to be
used with water-based materials only, and the
instructions in this manual refer to the use of this
applicator with water-based materials only. Water-
based materials are those defined as liquids which
do not sustain burning when tested in accordance
with ASTM D 4206 (FM 7260), as opposed to
solvent-based spray materials, which are liquids
that are flammable or combustible (FM 7260).
Combustible liquids are those liquids classified
as Class II or Class III, and have closed-cup flash
points at or above 37.8
°
C (100
°
F) (NFPA-33).
Flamable liquids are those liquids classified as
Class I, and haved closed cup flash points less
than 37.8
°
C (100
°
F) and a Reid vapor pressure
not exceeding 2068.6mm of Hg (40 psi) at 37.8
°
C
(100
°
F) (NFPA-33).
When more than one waterborne applica-
tor is fed from a common isolated fluid supply,
there is a potential for electrical energy dis-
charge through any other applicators when
one applicator is triggered. Depending upon
the system capacity, this discharge could be
hazardous. It is best to only install one appli-
cator per isolated supply.
