The A.J. Antunes 8621204007 Pressure Switch 0.017″–6″ WC is a sensing unit used to relate air flow applications in HVAC systems. It detects differential or static pressure within a defined range to signal control systems when preset thresholds are reached. It is used in ductwork, blower housings, or across filters. It provides input to fans, safety circuits, or controllers. Its role is to support accurate air flow monitoring and protect system operation by initiating responses when pressure conditions change in residential, commercial, or industrial settings.
