Fire damper circular RF-T CR60 Ø 180 mm

Description

CR60 circular fire-resistant damper that is used to prevent fire spreading through wall penetrations in air ducts. They feature a modular mechanism located completely outside the wall. The CR60 circular fire damper is fire-resistant during 60 to 90 minutes. The galvanised steel tunnel is made of refractory materials and is available in different variants and sizes.

With this Ø 180 mm fire damper, you are guaranteed minimal pressure loss thanks to the thin damper blade (20 mm), the fusible link in line with the damper blade and the transmission outside the tunnel. When the temperature in the duct becomes too high (above 72 °C), the fusible link melts and shuts down the system.
