This premium Air Baffle, also known as an Air Pressure or Air Proving Switch, is a critical safety and performance component designed for high-efficiency HVAC systems and gas furnaces. Its primary function is to monitor the airflow generated by the inducer motor or blower, ensuring that the system has reached the correct pressure before allowing the ignition process to begin. By accurately 'proving' the air movement, this switch prevents the appliance from operating under unsafe conditions, such as venting blockages or mechanical failures. If your heating system is failing to ignite or throwing airflow-related error codes, replacing a faulty air pressure switch is a common and essential repair. Engineered for precision and long-term durability, this baffle helps maintain the energy efficiency and safety of your climate control equipment.
Type: Air Pressure Switch / Air Proving Switch
Size: Small
Application: Used in residential and commercial heating systems, forced-air furnaces, and air handling units to verify proper venting and inducer motor operation.
Specifications: Diaphragm-style pressure sensing mechanism; designed to detect differential air pressure; acts as a safety interlock for ignition sequences.
