RSK - Smoke protection damper

Smoke protection dampers manufactured by Aerotechnik E. Siegwart GmbH are shut-off devices against smoke in ventilation ducts and are used to prevent smoke entering ventilation systems. Smoke protection dampers protect against smoke suction by means of exhaust air openings in the building facade, against spreading of smoke in buildings via air circulation ducts and against smoke transition in joint exhaust air or conduction ducts. Smoke protection dampers are used in ventilation centres, or in ventilation ducts made of non-flammable materials. The installation position of the smoke protection dampers depends on the direction of the air flow. Smoke protection dampers close automatically via the spring return actuators and may only be used in conjunction with smoke detector devices, which are approved by a building authority. Smoke detector devices are not included in the scope of delivery of the smoke protection dampers! Smoke protection dampers are not fire resistant and are not suitable for use as fire dampers.
