The Rf-t CR120 circular fire damper offers up to 120 minutes of fire resistance and is available in compact diameters starting from 100mm. Its thin blade, fusible link aligned with the blade and externally positioned transmission help minimise pressure loss, while the galvanised steel tunnel keeps the damper lightweight.
Designed for installation where ventilation ducts penetrate fire-resistant compartment walls, the damper helps maintain the fire resistance of the wall and prevent smoke propagation. Rf-Technologies fire dampers are CE marked and can be supplied with different mechanisms to suit specific project requirements and local regulations.
