The unloader valve vents residual air from the pump head when the switch opens, reducing startup load and helping the motor restart more smoothly, while the switch automatically cycles between the unit’s cut-in and cut-out pressures to maintain target system pressure. The FC321075000 designation is listed in Rolair’s official parts catalog as a pressure switch with an unloader valve, confirming it as an authentic Rolair replacement component. Designed for Rolair electric models, this assembly integrates with the machine’s wiring and safety interlocks to provide a compact, direct-fit control option that avoids the need for extra fittings. It serves in applications where a Rolair compressor requires a reliable, factory-grade pressure-switch with unloader to enable automatic regulation and smoother starts, helping protect the motor from heavy startup current and maintain consistent air delivery.\u003c\/p\u003e\u003c\/div\u003e","brand":"ROLAIR","offers":[{"title":"New","offer_id":46284226724074,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-022.png?v=1788727428","url":"https:\/\/gtghardware.com\/products\/rolair-fc321075000-pressure-switch-with-unloader-valve","provider":"GTG Hardware","version":"1.0","type":"link"}
