Fireproof Butterfly Dampers SC120
Fire dampers SC120 offer a solution for small diameters. Two half round blades are held together by a fusible link. When the temperature rises above 72°C the fusible link will break. Thereby the two half blades are released and the fire damper is shut, preventing smoke or flames from passing through.
It is mounted inside ventilation canals that go through partition walls. The installation is done only at one direction, which follows the air movement. It has fire resistance for about 120 min.
