Campbell WJAVC-LF air volume control 1-1/4" MIPT 20-100 psi

Campbell WJAVC-LF air volume control

The Campbell WJAVC-LF is a deep-well air volume control designed for water-well systems that require automatic air-charge management. It suits installers and maintenance technicians who need a reliable component for maintaining proper air volume in pressure tanks. The unit connects directly into the tank and suction piping using standard 1-1/4 inch MIPT threads. Its zinc body provides durability in typical well-water environments.

1-1/4" MIPT tank and suction ports

Both the tank port and the suction port use 1-1/4 inch male iron pipe threads, allowing direct connection to matching fittings without adapters. This threading simplifies installation on compatible deep-well pump systems and reduces potential leak points. The zinc construction resists corrosion from ground water and extends service life in submerged or humid conditions. No additional accessories or software are included with the control.

20 to 100 psi pressure range

The control operates across a 20 to 100 psi range, covering the pressure bands found in most residential and light-commercial deep-well installations. It manages air volume effectively within this window, helping the pump maintain consistent delivery and preventing water-logged tanks. The maximum operating temperature is 100 degrees Fahrenheit, so the unit is not suited for high-temperature or geothermal applications. Systems requiring pressures above 100 psi or temperatures beyond this limit will need a different control.
