PROCESS PROCESS PROCESS PROCESS 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
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
overspray around and deposit it on the back surface
of the target. Therefore, a higher percentage of
the spray is deposited.

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 applicators
to be used. Lastly, this system can allow a user
currently possessing an RMA-202 bell system to
use spray applicators as well, with minimal conver-
sion required. The Evolver 202 solventborne
applicator line
consists of both 60
° and 90° single
and dual-headed 100 kV automatic electrostatic
applicators. Developed for use on robots, the
Evolver 202 spray applicator incorporates a unique
1/3 turn quick-disconnect spray head and a two
piece bolt together manifold cover, providing the
user an efficient tool for the electrostatic application
of coatings.
The Evolver 202 spray applicator also has the
ability to color change while spraying with no
voltage draw down, a true dual purge function
(depending on the unit purchased).
There are two single head models of the Evolver
202 applicator (see Figure 1). Each model differs
in the applicator to axis orientation of the spray
head. These models are:
A11918-0XX 60
° Single Head
A11918-1XX 90 ° Single Head
Two dual-head versions of the Evolver 202 appli-
cator 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 configura-
tions as follows:
A11918-2XX 60
° Dual Head
A11918-3XX 90 ° Dual Head
