THE RANSBURG ELECTROSTATIC
PROCESS
This process is a method for electrostatically applying
coatings to objects. A power supply produces a high
voltage charge which is supplied to the applicator,
creating an electrostatic field between the applicator
and the target object. The target is electrostatically
grounded through its support which may be either
stationary or moving.
A regulated fluid system delivers coating material to
the applicator, where it is atomized forming a spray
mist. There, under the influence of the electrostatic
field, the atomized coating becomes electrostati-
cally charged. The charged particles are attracted to
and deposited on the grounded target object. The
forces between the charged particles and the target
are sufficient to turn overspray around and deposit it
on the back surface of the target. Therefore, a higher
percentage of the spray is deposited.

Evolver 303 Dual Purge Robotic Atomizers - Introduction
EVOLVER™ 303 DUAL PURGE
SOLVENTBORNE SPRAY
APPLICATORS
The Evolver
™
303
Dual Purge Spray Appli-cators System
will allow for the use of spray applicators or bell ap-
plicators with minimal required down-time during
the switching process. This system can also operate
as a spray applicator system only that later can be
upgraded to allow for bell applicators having "Unilink
Technology"to be used. This system can allow a user
currently possessing an RMA-303 bell system to use
spray applicators as well, with minimal conversion
required. Lastly, this system is a true dual purge
system in that paint can be sprayed with full voltage
on, while simultaneously color changing the second
paint line. The Evolver 303
Dual Purge Solventborne
Applicator line consists of both 60
° and 90° single
and dual-headed 100kV automatic electrostatic ap-
plicators. Developed for use on robot, the Evolver
303 Dual Purge spray applicator incorporates a
unique 1/3 turn quick-disconnect spray head and a
one piece slide over manifold cover, providing the
user an efficient tool for the electrostatic application
of coatings.
There are two single-head models of the Evolver 303
Dual Purge Applicators (see Figure 1). Each model
differs in the applicator to axis orientation of the spray
head. These models are:
A12374-0XX 60
° Single-Head
A12374-1XX 90
° Single-Head
Two dual-head versions of the Evolver 303 Dual Purge
Applicator are also available (see Figure 1). The dual-
headed applicators are primarily used where high
volume fluid delivery is required. The dual-headed
applicator is available in two different configurations
as follows:
A12374-2XX 60
° Dual-Head
A12374-3XX 90
° Dual-Head
