Hubbell 69HAU1 Heavy Duty Air Compressor Pressure Switch, 115-150psi, with Unloader, 3/8" NPT

The rugged 69HAU1 pressure switch is pre-set to kick on at 115psi and turn off at 150psi which is extremely common for climate control applications or fire suppression applications. 69HAU1 includes an unloader line for 1/4" tubing or refrigeration copper. This switch is designed for the demanding requirements of larger, heavy duty commercial compressors. This switch is meant for slightly smaller and lower HP compressors than the 69HBU1.
