Single Smoke Extraction Damper for Fire Ventilation Systems
SEDS
Single Smoke Extraction Damper
Single smoke extraction dampers are critical components of fire ventilation systems, designed to effectively remove smoke, heat, and combustion products from individual fire compartments. They act as automatic shutters in ventilation ducts, opening in the event of a fire to ensure safe evacuation and facilitate the work of emergency services. Equipped with an actuating mechanism, they can also be operated manually.
