Ranco P30-3701 Oil Control 30067439-890 This ASME Section IV certifiedThe Ranco P30 3701 is a commercial grade lube oil protection control designed to prevent catastrophic compressor failure and bearing damage in pressure lubricated refrigeration systems. Engineered with a built in 90 second time delay, this mechanical oil pressure switch monitors the differential between the oil pump outlet and the crankcase pressure. If the effective oil pressure drops below the setpoint, the S30 time delay module initiates a
