{"product_id":"020-517","title":"020-517","description":"This high-precision air pressure switch is a vital safety component designed for HVAC systems and industrial heating equipment. Functioning as an air proving switch, it monitors the pressure differential within the system to ensure proper airflow and venting before allowing the appliance to initiate a heating cycle. With a versatile operating range of .17 to 5 inches Water Column (WC), this sensor detects blockages in the flue or failures in the inducer blower motor, preventing unsafe operating conditions. It is an essential replacement part for maintaining the efficiency and safety of commercial and residential furnaces, air handlers, and rooftop units.\u003cbr\u003e\nType: Air Pressure Switch\u003cbr\u003e\nSize: Standard\u003cbr\u003e\nApplication: Commonly used in residential and commercial furnaces, HVAC air handlers, rooftop units (RTU), and boilers to verify combustion air flow and venting integrity.\u003cbr\u003e\nSpecifications: Pressure Setting: .17 to 5.0 inches WC (Water Column); Function: Air proving and safety interlocking; Compatibility: Suitable for systems requiring precise differential pressure monitoring.","brand":"BCFurnace","offers":[{"title":"SWITCH, AIR .17-5\" WC PRESS \/ 020-517","offer_id":50341953601821,"sku":null,"price":328.76,"currency_code":"CAD","in_stock":true},{"title":"SWITCH, AIR .17-5\" WC PRESS \/ SWT01943","offer_id":50341953634589,"sku":null,"price":328.76,"currency_code":"CAD","in_stock":true}],"url":"https:\/\/bcfurnace.myshopify.com\/products\/020-517","provider":"BCFurnace","version":"1.0","type":"link"}
