Circular fire damper with a fire resistance of up to 60 minutes. The damper collar and short damper tunnel guarantee quick and easy
mounting, both in surface and remote mounting. The optimised design of this fire damper ensures excellent aeraulic and acoustic
performance. Available in diameters 100-630 mm.
Fire dampers are installed where air ducts penetrate fire-resistant compartment walls. Their role is to restore the fire resistance grade
of the penetrated wall and to prevent smoke propagation. Fire dampers are distinguished by their degree of fire resistance, by their
aeraulic properties as well as by their installation ease. Rf-Technologies’ fire dampers are all CE marked. They can be equipped with
various types of mechanisms depending on the specific needs linked to the project or to the local regulations.
