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.
The EPD1H-AA3 by Barksdale stands out as a mechanical pressure differential switch, specifically crafted for industrial environments that demand meticulous control over pressure variances between two designated points. Engineered with a diaphragm and spring mechanism, this compact and dependable device swiftly detects pressure fluctuations, activating electrical output in accordance with pre-established thresholds. Recognized for its robust construction and precision, the EPD1H-AA3 Barksdale pressure switch ensures high reliability. Installation and adjustment are a breeze, seamlessly integrating into existing systems. Furthermore, it presents a cost-effective solution, making it an ideal choice for applications where budget considerations are paramount, without compromising performance or reliability.
