Application Smoke Dampers, Smoke Protection Dampers

Smoke dampers are an important part of automated smoke extraction systems built e.g. to keep vital escape routes smoke-free if a fire breaks out. Smoke extract dampers are all equipped with electric actuators and must remain functional during fires for at least 30 minutes.

Smoke protection dampers are used to prevent smoke from spreading in central ventilation plants with full fresh air systems to systems which have the supply air mixed with recirculated air, and in the case of older systems to make them smoke safe. They are not suitable for taking over the function of fire dampers.
