THE RANSBURG
ELECTROSTATIC
PROCESS
This process is a method for electrostatically apply-
ing 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
electrostatically 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 over-
spray around and deposit it on the back surface
of the target. Therefore, a higher percentage of
the spray is deposited.
INTRODUCTION
EVOLVER 303™
SOLVENTBORNE SPRAY
APPLICATORS
The Evolver 303 Spray Applicators System
will allow for the use of spray applicators or bell
applicators 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 ap-
plicators to be used. Lastly, this system can
allow a user currently possessing an RMA-303
bell system to use spray applicators as well, with
minimal conver-sion required. The Evolver 303
Solventborne Applicator line consists of both
60° and 90° single and dual-headed 100 kV au-
tomatic electrostatic applicators. Developed for
use on robots, the Evolver 303 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 Applicator (see Figure 1). Each model differs
in the applicator to axis orientation of the spray
head. These models are:
A11976-0XX 60° Single Head
A11976-1XX 90° Single Head
Two dual-head versions of the Evolver 303 Ap-
plicator 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:
A11976-2XX 60° Dual Head
A11976-3XX 90° Dual Head
