Smoke exhaust dampers

How does a smoke exhaust/control damper work?

How does a smoke control/exhaust damper work?
Smoke is considered to be as dangerous as fire, if not more. Smoke control solutions are designed to evacuate smoke and heat in case of fire. They create a smoke-free zone to facilitate the evacuation of people under good visibility conditions. Rf-Technologies smoke control shutters and dampers are normally closed, and open locally in the event of fire.

  1. Smoke control dampers and shutters are installed in (or connected to) smoke control shafts.
  2. Their opening is controlled by the central fire safety system that sends a trigger to the mechanism.
    The lower damper brings fresh air in while smoke is evacuated through the upper damper.
