Description
The A.J. Antunes 801111301 Differential Air Pressure Switch is a sensing control unit designed to detect changes in air pressure between two points in a system. It features an adjustable range of 0.07″ to 1.7″ water column with a blue spring calibration for setting sensitivity based on application requirements. In HVAC systems, it is commonly used in air handling units, furnaces, and ventilation equipment to verify airflow conditions and operational responses when pressure levels shift. The switch helps as a monitoring element that reacts to pressure variation assisting in ensuring safe and coordinated system performance.
