Product Details

Description

This premium air pressure switch is a vital safety component for residential and commercial heating systems. Functioning as an air proving switch, it monitors the vacuum pressure created by the draft inducer motor to ensure proper airflow before the ignition sequence begins. By verifying that the exhaust system is clear and the fan is operating at the correct speed, this pressure switch prevents unsafe operation and promotes efficient fuel combustion. Whether you are troubleshooting a boiler that won't ignite or performing routine furnace maintenance, this reliable sensing switch is designed to restore safety and performance to your HVAC equipment.
