Pressure Controls

P30 Pressure Switches

The P30 oil differential pressure switch is for use with all refrigeration with compressors using external oil pumps with refrigerants. It protects the compressor against loss of lubricating oil pressure which could otherwise cause severe bearing damage resulting in a compressor breakdown.
Connected to the crankcase and oil pump by capillaries, the P30 senses the difference between the pressure in the crankcase and that of the outlet side of the oil pump.
