Specifications
Smoke and heat extraction dampers - multi are closures in the pipework of smoke extraction devices. In the event of a fire, the smoke and heat removal system open the dampers in the affected section, therefore enabling the extraction fans to remove combustion products and heat from the endangered areas.The damper slat is controlled by an actuator.The damper is fire resistant and is designed for systems with automatic or manual activation.Smoke dampers are intended for use in spaces with multiple fire compartments, which can be connected by a smoke extraction pipe tested according to EN 1366-8 or can be installed in the construction of the fire compartment.The dampers can be supplied with flange(s) or without flange(s), with cover grille(s).
