internal air pressure reduces the power requirement
considerably during this unloaded state. The pressure
switch will re-activate the solenoid valve allowing the inlet
valve to open upon sensing an air demand (reduced
pressure). This will allow the compressor to start
producing air again.
2.2.3 AIR INLET FILTER
See Figure 2-3 . The air inlet filter, which is integrated into
the compressor assembly, is a dry type replaceable
element that drops in directly on top of the inlet valve
assembly. It is accessible by removing the cover from the
top of the filter assembly. For routine maintenance of the
air filter, consult
Sections 6.2 and 6.3 for maintenance
schedules, and Section 6.6.1 for specific air filter
maintenance procedures.
2.2.4 SECONDARY SPIN-ON AIR/OIL COALESCER
See Figure 2-4 . The compressor assembly is fitted with a
secondary spin-on air/oil coalescer. The coalescer
element recovers the finer particles of residual oil that
remain in the air after primary separation occurs. The oil
that is collected in this element is “scavenged” back to
the compressor unit for re-use. This element will need to
be replaced from time to time as part of normal
maintenance.
For routine maintenance of the spin-on air/
oil coalescer consult Sections 6.2 and 6.3 for schedule
intervals, and Section 6.6.6 for the specific coalescer
maintenance procedure.
2.2.5 MINIMUM PRESSURE/CHECK VALVE
See Figure 2-4 .
This combination valve, located on the
control manifold, serves two functions. First, the
minimum pressure valve maintains a pressure of
approximately 65 psig in the compressor to ensure oil
injection during load conditions and also to maintain
effective oil separation. Once this internal pressure is
exceeded, it will allow air to pass downstream to the
service outlet. The discharge check valve prevents air in
the service line from venting down through the
compressor during unload.
2.2.6 PRESSURE RELIEF VALVE
See Figure 2-5 .
The pressure relief valve is the last
safety device that will be activated. It is a spring-backed
normally closed valve that will vent excess pressures to
the atmosphere when excessive pressures are reached.
The Air N Arc 300 Series Power System is equipped with
a 200 psig relief valve. As the pressure begins to
