Product Details

Description

This Armstrong Air Pressure Switch is a critical safety component designed for residential gas furnaces and HVAC systems. Functioning as an air proving switch, it monitors the draft created by the inducer fan to ensure combustion gases are being safely exhausted through the vent pipe. With a calibrated set point of 0.60" WC (Water Column), this switch prevents the ignition cycle if it detects restricted airflow or a blocked flue. It is a vital replacement part for restoring furnace reliability and maintaining home safety when the original sensor fails to close. Durable and precise, this pressure switch is engineered to meet the technical demands of forced-air heating equipment.
