{"product_id":"773-215","title":"773-215","description":"Ensure your heating system operates safely and efficiently with this high-quality air pressure switch. Specifically designed as an air proving safety device for residential and commercial HVAC systems, this component monitors the negative pressure generated by the draft inducer motor to ensure proper venting before the furnace ignition process begins. By accurately sensing the vacuum level, it prevents the heating system from operating under unsafe conditions, such as a blocked flue, restricted exhaust, or inducer motor failure. This pressure switch is calibrated to a precise -1.00\" WC (water column) set point, providing reliable performance and peace of mind. It is a critical replacement part for restoring the safety sequence and functionality of gas-fired furnaces and air handling units.\u003cbr\u003e\nType: Air Pressure Switch\u003cbr\u003e\nSize: Standard\u003cbr\u003e\nApplication: Used in gas-fired furnaces, heating units, and HVAC systems to monitor combustion air airflow and exhaust venting safety.\u003cbr\u003e\nSpecifications: Pressure Setting: -1.00\" WC (Water Column); Function: Air Proving \/ Vacuum Sensing; Application: Inducer motor safety circuit","brand":"BCFurnace","offers":[{"title":"NORDYNE PRESSURE SWITCH -1.00\" WC \/ 773-215","offer_id":47251584155933,"sku":null,"price":112.66,"currency_code":"CAD","in_stock":true},{"title":"NORDYNE PRESSURE SWITCH -1.00\" WC \/ 632452","offer_id":47251584221469,"sku":null,"price":112.66,"currency_code":"CAD","in_stock":true},{"title":"NORDYNE PRESSURE SWITCH -1.00\" WC \/ 632452R","offer_id":47251584188701,"sku":null,"price":112.66,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0836\/7298\/9981\/files\/c21b1b8bf35e471c9b1bb48709917033.webp?v=1773959098","url":"https:\/\/bcfurnace.myshopify.com\/products\/773-215","provider":"BCFurnace","version":"1.0","type":"link"}
