Dwyer Instruments 1910-20 Differential Pressure Switch 4"-20" WC

The Dwyer Instruments 1910-20 Differential Pressure Switch is a precision part used in measuring and regulating differential pressure in HVAC systems, with a pressure range of 4”-20” water column. This switch works based on pressure differentials from two different points and was successful in controlling the airflow and the performance of equipment such as filters, fans, ducting systems, and many more. It optimizes the pressure differential to improve system efficiency, lower energy use, and extend equipment durability. The advantages of this differential pressure switch include better IAQ, better comfort, and timely notification of when the filters are dirty or there is some other problem.
