The APW80 includes a threaded port for a Schrader valve. Anyone who maintains the aeration system can test the backpressure at the pump with a pressure gauge. High backpressure means the pipe, tubing, or diffuser needs attention. You can test air throughput without opening the system.
The APW80 includes built-in protection devices. A safety switch and thermostat protect internal components from diaphragm breaks or abnormal internal temperature buildup.
