Design
mcr DOR smoke door dampers consist of a casing with a rectangular cross-section composed of fire-
proof boards, a moving damper blade in the form of two wings and an automatically activated trigger and
control mechanism. Special design casing with impregnated fire-proof boards are used in chemically
aggressive environments. The damper casing total thickness is 110 mm. The damper blade is made of a
fire-proof panel with the total thickness of 40 mm. At the corners and along the entire perimeter of the
casing, there are steel reinforcements with a rivet nut system, enabling the installation of masking grilles
and frames for connecting steel ventilation ducts.
