Damper Types

Static Fire Dampers

Ceiling Radiation Dampers

Dynamic Fire Dampers

Single action, one curtain, static damper.  Once tripped, this damper locks in place, preventing airflow through the HVAC duct and preventing fire from transitioning from one side of the wall to the other. If there is significant airflow at the time of tripping, there may not be enough spring push to close and lock the damper.

Dynamic Fire Dampers

Ceiling Radiation Dampers

Dynamic Fire Dampers

Single action, multi-vane curtain, dynamic fire damper.  Once tripped, this damper locks in place, preventing airflow through the HVAC duct and preventing fire from transitioning from one side of the wall to the other. These dampers are designed to close with significant airflow pressure, such as when the airflow is designed to continue in the event of a fire.

Ceiling Radiation Dampers

Ceiling Radiation Dampers

Ceiling Radiation Dampers

Single action, butterfly static damper. Once tripped, this damper locks in place, preventing airflow through the HVAC duct and preventing fire from transitioning through the ceiling.

Smoke Dampers

Fire/Smoke Combination Dampers

Ceiling Radiation Dampers

Motorized multi-blade damper usually controlled by an engineered system to evacuate smoke from the building.  Designed to operate in high static pressure ducts.

Fire/Smoke Combination Dampers

Fire/Smoke Combination Dampers

Fire/Smoke Combination Dampers

Motorized multi-blade damper, typically connected to a duct mounted smoke detector and will close when fusible link melts, upon signal from smoke detector and power loss.

Fusible links

Fire/Smoke Combination Dampers

Fire/Smoke Combination Dampers

Examples of fusible links.  These links are designed to release at specific temperatures.  Typical temperatures are 165 degrees and 212 degrees and have different release pressures.
