A.J. Antunes 801111303 Differential Pressure Switch W/Red Spring 0.1"-24" W.C JD-2

The Antunes 801111303 Differential Air Pressure Switch W/Red Spring is designed to precisely measure air flow in HVAC systems for maximum equipment efficiency. Used for differential air pressure measurement and control circuit initiation, thresholds are crossed. This includes proper airflow in ductwork, filter performance measurement, and automatic adjustment of fan or blower operation. The pressure range from 0.1 to 24 inches W.C. allows for adjusting the performance to the specific system requirements. The robust red spring contained in it provides accurate pressure detection, safeguarding equipment against unsafe pressure.
