Model “CA” – Load Genie® for Tube Compression Fitting & Model “PA” – Load Genie® for Pipe
A compressor running in a “start/stop” mode operates more efficiently if the pressure trapped in the compressor head and discharge line is released after each pump-up cycle. This allows for a smoother start and the use of a motor with lower starting torque.
The most convenient way to release this trapped pressure is to use the Load Genie® combination check and unloader valve. Install the valve in the compressor discharge line and the Load Genie® will do the rest.
The Load Genie® senses air flow when the compressor is running and closes an unloading orifice port. When airflow stops (ex: when the pressure switch turns off the motor), the Load Genie® opens the unloading orifice to release head pressure, and a built-in check valve keeps receiver air from leaking back into the discharge line and compressor head.
Alternative methods rely on external un-loading valves mounted on the pressure switch or compressor. The external un-loading valves are connected with the appropriate tubing and fittings to the compressor discharge line or compressor head. A tank check valve is also required. The system, then, consists of the unloading valve, connecting the tubing with the appropriate fittings, the tank check valve and the labor for installation.
