Carrier 060B2007 Oil differential Control 29 " -170PSIG 120S delay

The Carrier 060B2007 Oil Differential Control is a safety device meant for use in Carrier oil fired HVAC systems. It is 3.9” long, 7” wide, and 1.4” tall and serves to protect the system from pressure variations between the oil supply line and the crankcase. This pressure differential is essential to maintain the proper lubrication of the compressor. The 060B2007 connects with a 1/4-“ flare fitting and has a time delay of 120 seconds before triggering the shut-off if the pressure difference is less than -170 PSIG. This time delay prevents the system from shutting down as a result of pressure fluctuations that are only temporary.
