This OEM replacement part is commonly listed as compatible with VT‑series units, with examples including VT631538, VT613106, EX800700AJ, and VT631900, making it a standard choice when servicing Campbell Hausfeld portable or tank‑mounted systems. In many installations it is paired with a CV220301AJ check valve (1\/2\" MPT x 1\/2\" tube inlet) to regulate airflow from the pump to the tank while preventing backflow and aiding recharge efficiency. Campbell Hausfeld manuals and replacement-part catalogs confirm CW209000AJ as the pressure‑switch component for these configurations, underscoring its role in 4‑port switch assemblies with unloader functionality. \u003c\/p\u003e\u003c\/div\u003e","brand":"CAMPBELL","offers":[{"title":"New","offer_id":51677649043758,"sku":null,"price":65.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_657e2f4b-dbf5-4361-a824-2296299812cf.jpg?v=1769565932","url":"https:\/\/plgautomation.com\/products\/campbell-hausfeld-cw209000aj-electrical-switch","provider":"PLG Automation ","version":"1.0","type":"link"}
