This high-performance pressure switch is a vital safety component for residential and commercial furnace and HVAC systems. Calibrated to a precise 0.80" WC (Water Column) set point, this air proving switch monitors the airflow within the draft inducer assembly to ensure the system is venting properly before ignition occurs. If your heating unit is experiencing ignition failure or intermittent shut-offs, this replacement air pressure sensor provides the reliability needed to restore safe operation. Designed to detect vacuum or pressure differentials, it acts as a safeguard against blocked flues and inducer motor failures, ensuring your heating equipment functions at peak efficiency.
