Air Line Modules
4-Regulator Air Control Module (246587)
This module includes the following components:
• Bleed-type Master Air Valve (B): for shutting off
and locking out the air supply from the entire supply
unit.
• Pump Bleed-type Master Air Valve (C): is installed
so the valve is easily accessible and located down-
stream from the air regulator. It can be used for a
safety lockout.
• Ram Air Regulators (N): separate air regulators to
control the ram up and down air pressures.
• Pump Air Supply Hose (H): connects pump air
regulator to the air motor.
• Follower Blow-off Valve Regulator (L): controls
air pressure to the follower blow-off valve.
• Air Filter (A) and Lubricator (P): conditions air to
the ram and pump. Pump air regulator (D) is part of
this assembly. An air line tube connects the ram air
to the ram air control module.
• Pump Air Regulator (D): adjusts air pressure to
control pump speed and outlet pressure (located on
the air control panel).
• Automatic Depressurization Valve (Q): exhausts
air from the system at shut off. The built-in timer
delays start up to allow material to heat thoroughly.
Refer to page 36-38.
WARNING
The bleed-type master air valve (C) is required to
relieve air trapped between this valve and the pump
after the pump air regulator is closed. Read warnings,
