Product presentation CR2
Product presentation CR2
Circular fire damper available in the largest dimensions (up to a diameter of 630 mm) with a fire resistance up to 120 minutes. Its
refractory tunnel is made of galvanised steel and its blade consists of asbestos-free panels, which are resistant to humidity.
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.
