Description
The York S1-02425006704 Air Pressure Switch with Bracket is a control unit used to monitor airflow and pressure changes in ducted systems. It operates by detecting differential air pressure, calibrated around 0.90 inches water column, to confirm proper fan or blower operation and safety responses when airflow is insufficient. In HVAC systems, it is commonly installed in furnaces, air handling units, and ventilation equipment to ensure safe system operation. The bracket allows secure mounting, and the switch plays a role in protecting components by verifying airflow conditions before system activation or continued operation.
