A 60 minute circular fire damper that fits on the face of the wall or out of the wall, for contractors who want a fast install on round duct from 100mm up to 630mm. What this is best used for the f-r60k goes where round ductwork passes through a fire-rated wall, shaft wall or floor and the compartment needs 60 minutes of protection. It is a good fit for commercial kitchens extract runs, office and retail ventilation, apartment risers and plant room penetrations where approved document b asks for the fire separation to be maintained through the duct. Why choose this over alternatives most cartridge dampers, such as the systemair f-c2, sit inside the wall line and top out at 200mm and around 6 m s. The f-r60k is mounted on or out of the wall with its quick mount kit, so the opening does not need to be built around the damper, and it handles up to 12 m s and 1200 pa across 17 sizes to 630mm. The trade-off is the rating: it is ei60 s only. If you need 90 or 120 minutes on a small duct, the f-c2 is the better choice.
