The CAMPBELL HAUSFELD fp018400av is a pressure switch rated for 95 to 125 PSI, designed to control the motor cut-in and cut-out cycle on air compressor systems. The switch monitors tank pressure and signals the motor to start or stop based on the set pressure range, maintaining consistent output pressure during operation. Licensed technicians and experienced compressor service pros install this type of switch as part of routine maintenance or failure replacement on portable and stationary air compressor units.
This pressure switch is suited for air compressor applications where the operating range falls between 95 and 125 PSI. It is a direct-fit replacement component intended for CAMPBELL HAUSFELD compressor equipment. Typical installation scenarios include residential garage compressors, light commercial service units, and contractor-grade portable compressors that require a functioning pressure switch to regulate motor cycling.
Designed as an OEM-style replacement pressure switch for CAMPBELL HAUSFELD air compressor equipment operating in the 95 to 125 PSI pressure range.
Installation should be performed by a qualified technician familiar with air compressor electrical and pneumatic systems. Before replacing the pressure switch, disconnect power to the compressor and fully depressurize the tank by opening the drain valve and any relief valves. The switch involves both electrical connections and a threaded pneumatic port, so follow applicable NEC guidelines for wiring and ensure all fittings are properly sealed before returning the unit to service.
