RGE circular insulating damper
RGE circular insulating damper
The RGE damper is used to manually balance and isolate a circular ducting system, while ensuring a very low leak rate.

RGE circular insulating damper
The sealed RGE manual damper balances airflow and isolates a circular ducting system. The manual RGE features a sealed disc to minimise air leaks between upstream and downstream of the damper in the closed position and double-lip airtight seals on each junction to minimise leaks with the rest of the system. Its top jumper enables overlaid insulation without covering the handle.
