Commonly installed in reciprocating air compressors, shop compressors, pneumatic systems, and industrial compressed air equipment requiring automatic pressure regulation. Maintenance technicians, compressor service providers, and equipment owners use this switch for compressor repairs, pressure control replacement, and compressed air system retrofits. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 data-section-id=\"5ms9th\" data-start=\"608\" data-end=\"625\"\u003eApplications:\u003c\/h3\u003e\n\u003cp data-start=\"626\" data-end=\"1126\"\u003eThe Air Compressor Pressure Switch is commonly used in industrial air compressors, automotive repair facilities, manufacturing plants, woodworking shops, and pneumatic tool systems where automatic compressor cycling is required. The 1\/4-inch four-port configuration allows connection of pressure gauges, safety valves, pressure relief devices, and unloader valves while the 25A rating supports direct motor switching on many single-phase compressor applications. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 data-section-id=\"5hg6bl\" data-start=\"1128\" data-end=\"1157\"\u003eTechnical Specifications:\u003c\/h3\u003e\n\u003cp data-start=\"1158\" data-end=\"2033\"\u003e• Product type: Air compressor pressure switch\u003cbr data-start=\"1204\" data-end=\"1207\"\u003e• Current rating: 25 A\u003cbr data-start=\"1229\" data-end=\"1232\"\u003e• Pressure setting (cut-in): 140 PSI\u003cbr data-start=\"1268\" data-end=\"1271\"\u003e• Pressure setting (cut-out): 175 PSI\u003cbr data-start=\"1308\" data-end=\"1311\"\u003e• Pressure differential: 35 PSI\u003cbr data-start=\"1342\" data-end=\"1345\"\u003e• Port configuration: 4-port\u003cbr data-start=\"1373\" data-end=\"1376\"\u003e• Port size: 1\/4 inch NPT\u003cbr data-start=\"1401\" data-end=\"1404\"\u003e• Connection type: Female threaded ports\u003cbr data-start=\"1444\" data-end=\"1447\" data-is-only-node=\"\"\u003e• Contact type: DPST mechanical contacts\u003cbr data-start=\"1487\" data-end=\"1490\"\u003e• Function: Automatic compressor start and stop control\u003cbr data-start=\"1545\" data-end=\"1548\"\u003e• Compatible equipment: Single-stage and two-stage air compressors\u003cbr data-start=\"1614\" data-end=\"1617\"\u003e• Switching method: Mechanical pressure-actuated contacts\u003cbr data-start=\"1674\" data-end=\"1677\"\u003e• Maximum operating pressure: 175 PSI\u003cbr data-start=\"1714\" data-end=\"1717\"\u003e• Mounting style: Tank or manifold mount\u003cbr data-start=\"1757\" data-end=\"1760\"\u003e• Application: Compressed air systems and pneumatic equipment\u003cbr data-start=\"1821\" data-end=\"1824\"\u003e• Operating environment: Industrial and commercial compressor installations\u003cbr data-start=\"1899\" data-end=\"1902\"\u003e• Typical accessories supported: Pressure gauge, safety valve, and unloader valve connections \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 data-section-id=\"1cz0398\" data-start=\"2035\" data-end=\"2059\"\u003eCommon Replacements:\u003c\/h3\u003e\n\u003cp data-start=\"2060\" data-end=\"2185\"\u003e• \u003cspan class=\"hover:entity-accent entity-underline inline cursor-pointer align-baseline\" role=\"button\" tabindex=\"0\"\u003e\u003cspan class=\"whitespace-normal\"\u003eCondor USA INC Air Compressor Pressure Switch Range 11NC2E\u003c\/span\u003e\u003c\/span\u003e\u003cbr data-start=\"2099\" data-end=\"2102\"\u003e• \u003cspan class=\"hover:entity-accent entity-underline inline cursor-pointer align-baseline\" role=\"button\" tabindex=\"0\"\u003e\u003cspan class=\"whitespace-normal\"\u003eSquare D 9013FHG54J59M1X Pressure Switch\u003c\/span\u003e\u003c\/span\u003e\u003cbr data-start=\"2141\" data-end=\"2144\"\u003e• \u003cspan class=\"hover:entity-accent entity-underline inline cursor-pointer align-baseline\" role=\"button\" tabindex=\"0\"\u003e\u003cspan class=\"whitespace-normal\"\u003eNason Pressure Switch\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e","brand":"PLG Automation ","offers":[{"title":"New","offer_id":51726788690222,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_423b05ee-67ee-433e-bae9-78ffd4add699.jpg?v=1770580565","url":"https:\/\/plgautomation.com\/products\/industrial-25a-140psi-175psi-1-4in-port-4way-pressure-switch","provider":"PLG Automation ","version":"1.0","type":"link"}
