DESCRIPTION OF COMPONENTS
SAFETY VALVE
The pop safety valve is set at 200 PSI and is located at the top of the air/oil sump. This valve acts
as a backup to protect the system from excessive pressure that might result from a malfunction.
AIR/OIL COALESCER
The coalescer is self-contained within a spin-on housing. When air is demanded at the service line,
it passes through the coalescer which efficiently provides the final stage of oil separation.
OIL RETURN LINE
The oil that is removed by the coalescer accumulates and is returned through an internal oil return
line leading to the compressor.
MINIMUM PRESSURE VALVE
The minimum pressure valve is located at the outlet of the coalescer head and serves to maintain a
minimum discharge pressure of 75 PSIG in operation, which is required to assure adequate
compressor lubrication pressure.
OIL FILTER
The compressor oil filter is a removable and cleanable screen built into the side of the compressor
housing. Screen replacement may be necessary after several cleanings.
COMPRESSOR OIL AND HYDRAULIC OIL COOLING SYSTEMS
The compressor cooling system consists of a combination hydraulic cooler and compressor cooler
mounted on the common frame. Compressor oil temperature is controlled by a thermal valve
located down stream of the oil filter. The thermal valve maintains the compressor oil temperature
at 185ºF. Cool air is drawn through the vented end panel and across the combo cooler. The air is
heated by the coolers and the hot air exits out the back vented panel . Allow for adequate
clearance (12") for the air to exit. Also, the package location should not be subjected to above
ambient air temperatures.
