Smoke dampers are passive fire protection products that help reduce the spread of smoke and other gasses from one space to another during the event of a fire.

Smoke dampers are passive fire protection products used in air conditioning and ventilation ductwork or installed in physical smoke barriers (e.g., walls). This may be done to prevent the spread of smoke from the space of fire origin to other spaces in the same building.

Smoke dampers are intended to restrict the passage of smoke through ducts or openings in building assemblies such as smoke barriers and corridor walls. Smoke dampers may be required where ducts penetrate through smoke barriers or smoke partitions, or at other locations within an engineered smoke control system.

Smoke dampers help preserve the integrity of smoke barriers like fire dampers do for fire barriers. A smoke barrier can be a wall, floor, or ceiling. A smoke damper prevents the spread of smoke throughout a building, keeping employees and residents safe from smoke inhalation and your property safe from smoke damage.

Smoke dampers are used when there is a need to install a smoke control system to protect the integrity of any fire barriers and to stop the movement of smoke around a building, which, if not controlled, could cause significant risk to the occupants and people evacuating in the event of a fire.
