SD – Smoke Damper

SD

Rickard smoke dampers are used to control the passage of smoke through a building. The smoke damper is suitable for supply air and extract air systems. During normal operation the damper blade is closed and is opened to enable smoke to be extracted from the building. When there is smoke in the building the motor can be driven open or closed depending on the strategy and will typically fail open if power is lost to the motor. Please contact Rickard for your requirement.
