Product presentation CU2
Rectangular fire damper available in the largest dimensions, with battery conform to the European norm up to 3050x1650 mm. Fire
resistance up to 120 minutes. The refractory casing is made of asbestos-free panels, which are resistant to humidity. Its many options
make the CU2 damper a universal reference on the market.
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.
