Design
The mcr FID WING fire damper consists of a casing with a round cross-section, a movable cut-off partition and a
release and control mechanism that is automatically activated after the thermal fuse is actuated. The damper housing
is made of steel sheet. In the housing of the device, on its perimeter, there is a ventilation and intumescent gasket.
The cut-off partition of the damper is made of a non-flammable plate. Additionally, the damper can be equipped with
microswitches indicating the position of the device partition. The damper can also be equipped with an air valve (air
diffuser), enabling the adjustment of the parameters of the ventilation system. The device is delivered complete with
two insulating bands. The manufacturer requires the installation of the bands according to the drawings included in
the Operation and Maintenance Manual in order to obtain the declared fire resistance.
