Smoke and heat extraction dampers - multi are closures in the ductwork 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 blade 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 duct 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).
Flanges and grilles are not installed on the damper, they are supplied loose. Flanges are required
to fit the cover grilles. Grills and flanges must be installed to the dampers only after installation of
the damper into the wall.
