Utica-Dunkirk 550001266 SPDT Pressure Switch 0.4" WC

The Utica-Dunkirk 550001266 Pressure Switch is designed to ensure the safety and optimal performance of an HVAC system. It measuring pressure variations within the range of 0.4 inches of water column. When set threshold is attained, the SPDT mechanism switches on or off circuits connected to it to regulate airflow. This switch is applied in furnaces, boilers, and ventilation systems to monitor and control combustion and air flow. The advantages are better system efficiency, fault detection, and energy savings due to optimal performance in typical conditions of HVAC systems.
