Description
The Barksdale EPD1H-AA40-Q4 Differential Pressure Switch is used in HVAC systems and has a J-Box and bracket included. Used in a pressure range of 3 to 150 PSI, it is suitable for monitoring and regulating pressure variations in systems such as air handling units and ventilation systems. This switch is designed to work at an amperage of 4 A to ensure the stability of the operation. They also make adjustments of pressure readings taken before and after certain components such as filters or fans; adjust airflow thus increasing energy efficiency and also giving an indication of developing error.
