The CR60 is a very light circular fire damper with a fire resistance up to 90 minutes, which is installed in ventilation ducts passing through a construction element in order to stop the propagation of fire. The refractory casing is made of galvanised steel. The blade consists of asbestos free panels, which are resistant to humidity. The CR60 can be equipped with a fusible link mechanism up to a motorised mechanism, completely out of the wall. The damper is especially designed for smaller diameters up to 315 mm.
