CU-LT up to 800x600mm

Optimised rectangular fire damper with a fire resistance up to 120 minutes. A minimal pressure loss is guaranteed thanks to the thin blade and the transmission located outside the tunnel. The damper is available in small dimensions (starting from 100 mm height). A galvanised steel tunnel contributes to the light weight of the damper.

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.

• Easy to install
• Optimal free air passage and minimal pressure loss
• Optimal acoustic performance
• Higher net building volume through compact size
• Air-tightness class C according to EN1751
