Campbell Hausfeld FP073600AV Pressure Switch Unloader Valve Kit

The Campbell Hausfeld FP073600AV Pressure Switch Unloader Valve Kit is a targeted replacement for the FP073600AV four-port pressure switch, restoring the unloader valve function that vents discharge air when the compressor shuts off. This kit centers on the unloader valve component CW212401AV, a verified replacement part used in FP073600AV assemblies, and supports Campbell Hausfeld portable air compressors rated around 125 psi. By renewing the unloader valve, the switch can relieve system pressure after shutdown, helping ensure a clean restart and maintaining proper cycling of the compressor. The FP073600AV designation appears in Campbell Hausfeld replacement parts illustrations as the 125 psi, four-port pressure switch that incorporates an unloader system, with CW212401AV identified specifically as the unloader valve. Installing this kit on FP073600AV units preserves compatibility with the original switch design and maintains consistent performance of the unload/bleed function integral to typical compressor operation. Use of genuine FP073600AV replacement components helps protect the pump, motor load, and discharge line by ensuring the unloader pathway remains clear and correctly sealed.
