COMPRESSOR OIL SYSTEM CHECK - The following readings are based on ambient temperature of
80
°
F (27
°
C) with the system in good condition. The compressor should be at operating temperature at
the time of the checks. One-half hour of loaded operation is usually sufficient to reach level-out operating
temperatures.
Air and Oil Discharge Temperature - 170
°
F to 200
°
F (77
°
C to 93
°
C) - Check with a thermometer at
the discharge housing.
Compressor Oil Inlet Temperature - 160
°
F to 175
°
F (71
°
C to 79
°
C) - Install a tee at the oil filter outlet
and check with a thermometer.
Oil Inlet Pressure - Check at the fitting in the line near the compressor oil inlet. With air receiver
pressure at 100 psi (6.9 bar), oil inlet pressure should be 80 to 90 psig (5.5 to 6.2 bar).
Oil Cooler Oil Pressure Differential - Check differential across the oil system by measuring oil inlet
pressure as described above.
Oil Cooler Temperature Differential - The oil temperature differential depends on the temperature of
the air at the oil cooler fan and cleanliness of the core faces. As ambient temperatures and core
restrictions increase, the oil cooler outlet temperature will increase. The oil inlet temperature is
approximately the same as the air discharge temperature.
