5.10 Compressor Oil Thermal Valve
The compressor oil thermal valve is a thermostatically controlled by-pass valve that allows varying
amounts of oil, depending upon the temperature, to by-pass the oil cooler.
The oil thermal valve directs
oil flow back to the compressor airend until the system reaches
170
°F. Once at system operating
temperature, the valve shifts, directing the flow through the oil cooler before returning to the compressor
airend.
Description of Components
5.5 Pressure Relief Valve
This valve vents separator tank pressure to atmosphere should the pressure inside the tank exceed 200
PSI.
5.6 Engine Air Filter
The engine air filter is a two stage, dry type intake filter with a gravity evacuator and replaceable internal
element. On the outlet of the engine air filter is an air filter restriction indicator. This indicator serves as
a maintenance tool.
5.7 Compressor Air Filter
The compressor air filter is a two stage, dry type intake filter with a gravity evacuator and replaceable
internal element. On the outlet of the compressor air filter is an air filter restriction indicator. This
indicator serves as a maintenance tool.
5.8 Cooling Systems
I.
Engine Radiator
The radiator is designed to dissipate the heat load of the engine and is mounted in front of the
specially selected engine fan. Hot engine coolant is passed through the interior of the radiator and
heat is transferred to the air that passes across the cooling fins.
II. Compressor Oil Cooler
The compressor oil cooler is designed to dissipate the heat created during the compression of air.
The oil cooler is mounted beside the engine radiator. This works similar to the engine radiator but is
designed to withstand the full compressor system working pressure.
5.9 Compressor Oil Filter
The compressor oil filter is a full flow, spin-on canister. It has been specially designed to handle 200
PSI. The oil filter is mounted downstream of the separator tank to ensure all contaminants are pre-
vented from being passed on to the compressor oil cooler.
