The Rf-t CR2 circular fire damper is designed for larger-diameter applications, with sizes available up to 630mm diameter and fire resistance of up to 120 minutes. Its refractory tunnel is manufactured from galvanised steel, while the blade is made from asbestos-free, moisture-resistant panels.

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.
