Campbell CW207576AV Pressure Switch Unloader Valve Kit

CW207576AV is a pressure switch kit for Campbell Hausfeld air compressors that combines a pressure-switch assembly with an integral unloader valve and lever, designed to vent trapped air from the pump head when the unit shuts off and prepare for a smooth restart. The kit is specified as a 95–125 psi switch and includes a 1/4" NPT connection for the unloader line (some listings also note a 1/4" compression fitting option for the unloader line), making it a direct replacement that mates with Campbell Hausfeld FP200000AV family models and related equipment. A newer replacement, CW210100SJ, is marketed as 100/125 psi and explicitly replaces CW207576AV, reflecting ongoing compatibility in the field. This assembly provides the essential components for reliable pressure control in single‑stage air systems, combining the switch, lever, and unloader valve in one unit for straightforward installation on compatible compressors.
