Description
The Barksdale EPD1H-AA3 Single Setpoint pressure differential switch is used to Monitor Pressure differences Across Filters, Dampers, and other HVAC components. It works is that there is a pressure differential across the component which, when it goes beyond a specified level, controls the signal. This switch uses pressure changes which in turn operate a snap action switch to give a stable and repeatable output. Filter Clogging Monitors track filter efficiency signals to the maintenance personnel when filters are full and require replacement due to rates and high energy use. Optimum Airflow Across HVAC Equipment Provides the necessary flow across fans and coils, protecting them from the negative effects of pressure drops, and increases system efficiency and operating economy.
