🔥 What Is a Fire Damper?
A fire damper is a passive fire protection device installed in ducts and air transfer openings. It prevents the spread of flames and smoke through HVAC systems by automatically closing when high temperatures are detected. Fire dampers are activated by a fusible link or heat detector, which causes the damper blades to shut, blocking airflow and containing fire to one compartment.
