The REA Process is an air atomized method for
applying coatings to objects electrostatically. The
REA system applies a high voltage DC charge to
the applicator nozzle electrode, creating an
electrostatic field 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 fluid system delivers coating
material to the atomizer. At the atomizer, air is
applied which atomizes the coating material forming
a spray mist which, under the influence of the
electrostatic field, becomes 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 over-spray around
and deposit it on the side and back surfaces of the
target. Therefore, a high percentage of the spray
is deposited on the target.

This is a combined air-airless atomization method
for electrostatically applying coatings to objects.
The M90 system applies a high voltage DC charge
to the applicator nozzle electrode, creating an
electrostatic field between the atomizer and the
target object. The target is electrically grounded
through its support, which may be either stationary
or moving.
A regulated high high high high high pressure fluid system delivers
coating material to the atomizer. There the coating
material is atomized by passing through an orifice
under pressure. The resulting spray mist then
becomes electrically charged under the influence
of the electrostatic field surrounding the atomizer.
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 side and back surfaces of the
target. Thus, a high percentage of the spray is
deposited on the target.

Power Supply Power Supply Power Supply Power Supply Power Supply
The 9040 Classic Power Supply converts standard
AC line voltage to a high frequency, low voltage
signal ranging from 0 to 10 Vrms. This signal is
supplied to the High Voltage Multiplier where it is
converted to DC high voltage. The high voltage
DC is then transferred from the 9040 Classic
Power Supply to the REA/M90 applicator through
a super flex high voltage cable. The voltage/
current characteristic is designed to optimize the
charging process under varying load conditions
and to limit the operating current to a safe maximum
value.
In addition to supplying high voltage output to the
applicator, the 9040 Classic Power Supply also
provides controls for AC power ON/OFF, infinite
high voltage adjustment, a high voltage meter, a
current meter, a POWER ON indicator, a HIGH
VOLTAGE ON indicator, and a CURRENT
OVERLOAD indicator and reset switch. Addition-
ally, output terminals are provided for remote
overload reset and interlock connections for a
conveyor, exhaust fan and high voltage control on
all 9040 Classic Power Supplies.
