  • Page 2: General Information

    ® NORDfire | FDMQ General information Description 1.1 Fire dampers are shutters in ducts of air-conditioning devices that prevent spreading the fire and combustion products from one fire segment to the other one by means of closing the duct in the points of fire separating constructions.
  • Page 3 ® NORDfire | FDMQ 1.3 Working conditions Right damper function is secured under the following conditions: Maximum air circulation speed: 12 m/s Maximum pressure difference: 1200 Pa The air circulation in the whole damper section must be secured as steady on whole surface.
