It delivers a factory setting of 95 psi cut-in and 125 psi cut-out (adjustable to suit your system), with an open\/close range of 140\/175 psi and a differential typically around 30–40 psi. The unit’s air supply is 1\/4\" FPT and the unloader line connects via a 1\/4\" compression fitting, allowing venting to relieve tank pressure for easier motor start. The switch body is described as a 4-port unit, with electrical inlets on both sides (no bottom electrical inlets), and a built-in unloader valve for releasing air through the unloader line. At approximately 2 lb, it’s a compact replacement that can fit many Campbell Hausfeld and non‑brand compressors that use this style of switch. The CW2075-30 is commonly used as a replacement part to restore proper cycling and unloading behavior in single-stage systems, where precise pressure cycling and reliable unloading are essential for efficient operation. \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003c\/div\u003e","brand":"CAMPBELL","offers":[{"title":"New","offer_id":51677640556846,"sku":null,"price":90.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_a094c34b-6245-4e20-8676-3e662185d4af.jpg?v=1769565818","url":"https:\/\/plgautomation.com\/products\/campbell-hausfeld-cw2075-30-pressure-switch-single-port-adjustable-unloader","provider":"PLG Automation ","version":"1.0","type":"link"}
