Ensure the safe and efficient operation of your heating system with this high-quality air pressure switch. Designed as a critical safety component for gas-fired HVAC units and commercial rooftop equipment, this air proving switch monitors the pressure generated by the inducer fan motor. It verifies that proper airflow and venting are established before allowing the ignition sequence to proceed, preventing the buildup of dangerous exhaust gases. This SPST (Single Pole Single Throw) switch is a reliable replacement for failing sensors that cause furnace short-cycling or ignition failure. Engineered for precision and durability, it helps maintain optimal combustion performance and equipment longevity in demanding heating applications.
