Hubbell 69HBU1 Heavy Duty Air Compressor Pressure Switch with Unloader Valve, 115-150si, 3/8"NPT

Heavy Duty Air Compressor Hubbell 69HBU1 Pressure Switch with Unloader Valve, 115-150psi, 3/8"NPT

The rugged 69HBU1 pressure switch is designed for the demanding requirements of larger, heavy duty commercial compressors. This is a more robust switch than the 69HA1 and capable of handling larger motor horse poweres. 69HBU1 is pre-set to kick on at 115psi and turn off at 150psi which is extremely common for industrial two stage air compressors. 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 69HBU1 includes a sturdy painted steel case and cover resists the harsh conditions encountered in industrial applications.
