The rugged 69HAU2 pressure switch is pre-set to kick on at 100psi and turn off at 125psi which is extremely common for climate control applications or fire suppression applications. 69HAU2 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 69HBU2.
The 69HAU2 includes a sturdy painted steel case and cover resists the harsh conditions encountered in industrial applications.
