The rugged 69HBU3 pressure switch is designed for the demanding requirements of larger, heavy duty commercial compressors. This is a more robust switch than the 69HAU3 and capable of handling larger motor horse poweres. 69HBU3 is pre-set to kick on at 30psi and turn off at 40psi which is extremely common for climate control applications or fire suppression applications. This switch does include an unloader valve pre-installed (this switch will still work if no unloader valve is required, simply leave the switch port open).
The 69HBU3 includes a sturdy painted steel case and cover resists the harsh conditions encountered in industrial applications.
