DESCRIPTION
The AGXV high volume, low pressure spray gun
(spray pistol) is used on automatic and semi-
automatic machines where mass production
spraying is necessary, or hand spraying is not
accurate enough. Models and application infor-
mation follows. All models are designed to pro-
vide maximum transfer efficiency by limiting air
cap pressure to 10 psi (0.7 bar) (in the U.S., this
complies with rules issued by SCAQMD and
other air quality authorities). Air cap pressure
can be measured with an optional air cap test kit.
See "ACCESSORIES" on Page 8.

Most finishing materials can be atomized with
either the 28 or 33A air caps. The 28 or 33A caps
should be used where possible as they con-
sume less air volume (CFM) and have slightly
better transfer efficiency than the 46 MP or
83MP air caps. However, more difficult to atom-
ize materials (i.e. low VOC's) or high flow appli-
cations over 12 oz./min. (360 cc/min.), are ideal
for the 46 MP maximum performer air cap, fluid
tip and baffle combination. Also available is the
83MP (maximum performer) for even higher
flows 17 oz./min. (510 cc/min.) and above and
higher viscosities. Refer to the air cap chart for
more information.
Note
This gun may be used with chlorinated
solvents. Aluminum is not used in fluid
passages. If using chlorinated solvents,
make sure all other fluid handling compo-
nents are also compatible.
A list of materials used in the construction
of this equipment is available upon request.

available, the inner (red) piston spring can be removed
which lowers the minimum cylinder air to approxi-
mately 37 psi (2.5 bar). Refer to "OPERATION", Pg. 4
