Explosion Hazard –
Incompatible Materials
Halogenated hydrocarbon sol-
vents for example: methylene
chloride and 1,1,1,-Trichloroethane are not chemically
compatible with the aluminum
that might be used in many system components. The chemical
reaction caused by these solvents reacting with aluminum
can become violent and lead to
an equipment explosion.
Follow the requirements of the Material Safety
Data Sheet supplied by coating material manufacturer.
Adequate exhaust must be provided to keep the
air free of accumulations of toxic materials.
Use a mask or respirator whenever there is a
chance of inhaling sprayed materials. The mask
must be compatible with the material being
sprayed and its concentration. Equipment must
be as prescribed by an industrial hygienist or
safety expert, and be NIOSH approved.
Aluminum is widely used in other spray application equipment - such as material pumps,
regulators, triggering valves, etc. Halogenated
hydrocarbon solvents must never be used with
aluminum equipment during spraying, ushing,
or cleaning. Read the label or data sheet for the
material you intend to spray. If in doubt as to
whether or not a coating or cleaning material is
compatible, contact your coating supplier. Any
other type of solvent may be used with aluminum
equipment.

INTRODUCTION
REA Automatic Applicators - Introduction
DESCRIPTIONS
The REA Automatic processes are an air atomized
method for electrostatically applying coatings to
objects. The REA Automatics apply a high voltage
DC charge to the applicator electrode, creating an
electrostatic eld between the atomizer and the
target object. The target is electrically grounded
through its support which may be either stationary
or moving.
A regulated pressure uid system delivers material
to the atomizer. At the time of triggering the applicator’s fan and atomization air is applied which
atomizes the material forming a spray mist. The
mist under the inuence of the electrostatic eld,
becomes electrically charged. The charged particles of material are attracted to, and deposited
on, the target. The forces between the charged
particles and the grounded target are sufcient to
turn most normal overspray around and deposit
it on the back surface of the target. Therefore,
a high percentage of the spray is deposited on
the target.
One of the many features of the REA Applicator
Automatic System is the electrical discharge which
is available from the resistive charging electrode is
limited to the optimum level of safety and efciency.
As the applicator electrode approaches ground,
the control unit and applicator circuitry shut down
the high voltage and current to the applicator. The
control unit must then be reset to continue to spray
electrostatically.
The REA Automatic Electrostatic Spray Applicators
are transformable between air spray and HVLP
spray technology. By changing a select few parts,
the applicator may be transformed to be operated
in either spray mode. (See “Spray Technology
Conversion Procedure” in the “Installation” section
for details.)
The REA 900A Applicator is designed with a mov-
ing trigger (shaft), so no forward mounted trigger
valve is required. The dump valve is mounted on
the rear bulkhead plate for ease of maintenance.
All uid connections in this applicator use “AN”
style ttings to eliminate “dead spots” in the uid
path for superior ushing.
The REA 9000R is a robot-mounted applicator for
hollow wrist robots produced by either FANUC or
ABB. The advantage of the REA 9000R applicator
is that it can be removed quickly and easily from
the robot mounting plate with the use of a threaded
retaining ring.
The REA 9000R incorporates two important safety
features. The rst being a break-away design
that will shear two (2) nylon mounting bolts if the
applicator comes in contact with the object being
sprayed. The second is the discharge which is
available from the resistive charging electrode is
limited to the optimum level of safety and efciency.
The REA 9000W (Not FM Approved) is an external
charge probe applicator designed to spray water-
borne coatings in systems utilizing a grounded uid
supply. Applicator features include: Probe Shroud
Air and Electrode Shroud Air. Low pressure air
exiting around the probe body and electrode wire
aid in keeping these components clean during op-
eration. These features help to maintain maximum
efciency of the applicators over a longer period
of time. The REA 9000W applicator also offers
conventional “classiC” high voltage technology.
The REA 9000R and 900A Series of applicators
apply -85kV DC charge to the coating materials at
the point of atomization. This series of applicators
is intended for use with grounded solventborne
coating systems. The REA 9000W Series of
applicators applies -70kV DC Charge. This elec-
trostatic charge allows a more efcient, uniform
application of coating material to the front, edges,
sides, and back of products. It is highly suitable
AA-99-02.5

REA Automatic Applicators - Introduction
Ransburg
for applying coatings to a variety of surface con-
gurations: large targets, small parts, tubular
wares, concave and recessed parts, etc. keeping
these components clean during operation. These
features help to maintain maximum efciency of
the applicators over a longer period of time.
These series of applicators include the automatic
applicator, low or high voltage cable, control unit,
uid hose, and air tubing.
The control unit provides voltage output to the
applicator and contains controls for AC on/off,
high voltage adjust, kV/microamp meter and triple
setpooint or analog input control.

ed BEFORE operating it! This is done with a
fully connected and operational system by
placing one lead of an ohmmeter to the inlet
tting and the other to the building electrical
ground (cold water pipe, building structure,
