Air Line Modules
WARNING
PRESSURIZED FLUID HAZARD AND
MOVING PARTS HAZARD
The bleed-type master air valve (C) and
auto depressurization valve (P) are re-
quired in your system to relieve air
trapped between this valve and the
pump after the pump air regulator is
closed. Trapped air can cause the pump
to cycle unexpectedly, which could result in serious
bodily injury, including splashing in the eyes or on
the skin and injury from moving parts.
4-Regulator Air Control Module (shown)
For more information, refer to Fig. 1 page 7 and Fig.
2 page 9. The following components are included
with the module:
Bleed-type Lock-out Master Air Valve (B) is used to
shut off and lock out the air supply from the entire
supply unit.
Bleed-type Master Air Valve (C) is required in your
system to relieve air trapped between it and the air
motor when the valve is closed (see preceding
Pressurized Fluid Hazard And Moving Parts
Hazard
WARNING). This bleed valve should be
easily accessible and located downstream from the
air regulator. It can be used for a safety lockout.
Pump Air Regulator (D) controls pump speed and
outlet pressure by adjusting the air pressure to the
pump. It is located on the air control panel up-
stream from the bleed-type master air valve.
Auto Depressurization Valve (P) exhausts air from
the system at shut off. The built in timer delays
start up to allow material to heat thoroughly.
Ram Air Regulator controls the air pressure to the
ram. There are separate air regulators to control
the ram pressure in the up and down directions.
Ram Air Supply Hose (H) connects the ram air
regulator to the air manifold.
Follower Blow-off Valve (N) controls the air pres-
sure to the follower blow-off.
FRL (filter, regulator, lubricator) (A), (D), and (I)
conditions the air to the ram and the pump. The
pump air regulator is located in this assembly. The
ram air is taken from this assembly; an air line tube
connects the FRL and the ram air control module.
Fluid Line Accessories
A fluid regulator (K) controls fluid pressure to the
gun/valve, and dampens pressure surges. Install the
fluid regulator in the position shown in the Typical
Installation, using adapters as necessary.
Vent Hood Kit
The vent hood assembly is designed to efficiently draw
fumes to the factory exhaust system during drum
change-out. This assembly requires connection to a
factory ventilation system that draws a minimum air
flow of 8.4 m
3
/min (300 scfm). This kit is required for
Polyurethane Reactive (PUR) applications.
