Ransburg Evolver Water Applicator 78863-90, 78863-60 - Manual (Page 10)

DESCRIPTION
The Ransburg Robot Waterbase Applicator RWA-EFM
Series Spray Applicators for highly conductive coat-
ings are air atomizing, fan pattern 100 kV automatic
electrostatic spray guns. The waterbase or solvent-
base paint is charged by the resistive electrode in
the spray head of the gun. These guns have been
developed for use on today's robots. These guns
were designed to be used with a voltage block sys-
tem such as the AquaBlock or isolated paint tanks.
A separate manifold assembly includes single low
voltage cable and the hosing required to operate
the spray gun. The guns are manufactured in either
60 ° or 90° head configurations.

EFM SPRAY GUN MODELS
Model # Description
RWA-EFM ELECTROSTATIC
SPRAY GUNS FOR HIGHLY
CONDUCTIVE COATINGS
There are two models of the RWA-EFM Spray Guns
for highly conductive coatings. (See Figure 1) All
internal gun componenets are basically the same;
the only apparent differences is the head angle,
either 60 ° or 90°.
The spray gun has three major parts: the spray head
assembly, the valve manifold section, and the valve
housing section. (See Figure 1) The gun body is fab-
ricated with the fluid, air, and dump passages. There
is a removable check valve to allow air to blow down
the dump line while paint is spraying. This prevents
grounding out of the applicator when spraying highly
conductive materials.
