Air damper is designed specifi cally for regulating air fl ow in general-purpose networks, including at low temperatures (down to minus 40°C), has design features that prevent fl ow breakdown, pressure hammers, jamming in intermediate positions and allow precise control of air fl ow resistance of the ventilation network.

They are made only of rectangular cross-section.

Range of connection dimensions and useful cross-section dimensions fully corresponds to the size range of GMK-R series dampers without restrictions or additions.
