Description
Product Overview
The 70°C Fire Damper is a critical fire protection device designed for HVAC and ventilation duct systems. Installed at fire-rated walls, floors, and ventilation openings, it automatically closes when the ambient temperature reaches 70°C, preventing the spread of fire, smoke, and hot gases through ductwork.
Equipped with a fusible link temperature sensing mechanism, the damper remains open during normal operation to allow unrestricted airflow. In the event of a fire, the fusible element melts at 70°C, triggering the damper blades to close automatically and isolate the affected fire compartment.
Widely used in commercial buildings, hospitals, hotels, office complexes, shopping malls, industrial facilities, and public infrastructure projects, the 70°C Fire Damper plays a vital role in passive fire protection systems and building safety management.
