Product Details

Description

This premium air pressure control switch is an essential safety component designed for high-performance HVAC systems. Functioning as an air proving switch, it monitors the pressure differential within the system to ensure proper airflow and venting before allowing the combustion process or heating cycle to begin. Engineered to open at -.45 inches water column (WC), this switch prevents hazardous operation by detecting blockages in the flue or failures in the inducer motor. Reliable and precise, this component is a common replacement part for furnaces and rooftop units where maintaining specific static pressure levels is critical for equipment longevity and occupant safety.
