{"product_id":"campbell-hausfeld-cw212201av-pressure-switch","title":"Campbell Hausfeld CW212201AV Pressure Switch","description":"\u003cdiv\u003e\u003cp\u003eCW212201AV is a Campbell Hausfeld universal pressure switch with an integrated unloader valve, designed as the direct replacement for CW212200AV in Campbell Hausfeld air compressors. It carries a 105 psi cut-in and 140 psi cut-out pressure range, a common specification for Campbell Hausfeld single‑stage units, and is frequently sold as CW212201AV-S by distributors. The unloader valve vents the air tank when the switch opens, reducing compressor restart strain and helping to prevent short cycling. Campbell Hausfeld's official service and parts literature identifies CW212201AV as the universal replacement for CW212200AV and lists it for use with models such as CE400000AJ, CE410400, and TQ310101, signaling broad compatibility within the brand's line. The CW212201AV designation appears in Campbell Hausfeld manuals, including the TQ3104 single-stage compressor manual, and is described in replacement parts catalogs alongside other CW2-series switches, underscoring its role as a standard, factory-compatible component for a wide range of Campbell Hausfeld products.\u003c\/p\u003e\u003c\/div\u003e","brand":"CAMPBELL","offers":[{"title":"New","offer_id":51677628891438,"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_b1783b1d-3f09-49d5-9d3f-98b7accd50cf.jpg?v=1769565788","url":"https:\/\/plgautomation.com\/products\/campbell-hausfeld-cw212201av-pressure-switch","provider":"PLG Automation ","version":"1.0","type":"link"}
