The Rf-t CU-LT rectangular fire damper offers up to 120 minutes of fire resistance and is available in compact dimensions, starting from just 100mm in height. Its thin blade and transmission positioned outside the tunnel help minimise pressure loss, while the galvanised steel tunnel contributes to the damper’s low weight.
Fire dampers are installed where ventilation ducts penetrate fire-resistant compartment walls, helping to maintain the fire resistance of the wall and prevent smoke propagation. The CU-LT is CE marked and can be supplied with different types of mechanisms to meet specific project requirements and local regulations.
