(water-cooled only)
Continually monitors injection fluid pressure and shuts
down the compressor in the event of low fluid pressure.
Continually monitors fluid filter differential and generates
an alarm when the fluid filter needs replacement.
Monitors condition of compressor inlet air filter and indi-
cates when replacement is required.
Indicates fluid level in the sump. Proper level is not to fall
below the center of the sight glass. Check level when
compressor is shut down. DO NOT OVERFILL.
Regulates flow of fluid to and around the cooler.
Designed to maintain a minimum operating temperature
of 180ºF (82ºC); used for fast warm-up on start-up.
Maintains minimum of 50 psig (3.4 bar) in the compressor
sump. Valve piston restricts receiver air discharge from
receiver/sump when pressure falls to 50 psig (3.4 bar).
Also incorporated in this valve is a terminal check valve
which prevents line pressure backflow into the sump dur-
ing unload conditions and after shutdown.
Protects compressor by venting compressed air in
excess of 200 psig (13.8 bar) to atmosphere.
Regulates the amount of air allowed to enter the air com-
pressor. This regulation is determined by the amount of air
being used at the service line. Also acts as a check valve
to prevent reverse compressor rotation at shut down.
Bypasses the pressure regulator valve causing the inlet
valve to close when the compressor reaches maximum
operating pressure. Also activates blowdown valve.
Regulates the amount of cooling water used in the cooler
to keep the compressor running at a normal operating
temperature of 145ºF (63ºC) [165ºF (74ºC) for 24KT].
