One of the most critical components of fire safety systems in large-scale buildings is the multi-blade fire damper. These dampers are designed to prevent the spread of fire and smoke through ventilation ducts, especially in wide duct systems. By controlling airflow, they help contain fires and protect adjacent zones from exposure, making them essential in commercial and industrial structures.
Purpose and Functionality of Multi-Blade Fire Dampers
The DTY-02 model multi-blade fire damper is manufactured from galvanized steel sheets, offering long-lasting durability. In the event of a fire, when the ambient temperature reaches 72°C, the built-in thermal fuse melts and activates the mechanism, causing the blades of the damper to close automatically. This prevents the fire from spreading through the ventilation system to neighboring spaces.
In motorized versions, the damper closes via an electric actuator upon receiving an emergency signal. This feature enables full integration with building automation and fire safety systems.
Key Features
Leakage Prevention: The damper's blade mechanism is designed for air-tight sealing.
Fire-Resistant Seal: Equipped with an intumescent gasket around the blade, which expands when exposed to high heat, ensuring airtight sealing during a fire.
Optional Accessories: Can be supported with additional casing, servomotor, and microswitch depending on the project needs.
Common Applications
Shopping malls
Hospitals
Factories
Office buildings
High-rise residential projects
Industrial facilities with main ventilation lines
Thanks to their ability to handle large air volumes, multi-blade fire dampers are ideal for ventilation systems with wide ducts and heavy airflow demands.
