description The present disclosure relates to a damper (1) and a method (100) for a ventilations system. The damper comprises a plurality of rotatable damper blades (4), a rotatable torque transferring element (3) connected to a blade wherein each pair of adjacent blades are rotatable in opposite directions (Ri, R2), and a link (2) connecting at least two of the torque transferring elements, The method comprising the steps of applying a drive force causing a first blade to rotate in a first direction, causing, by means of interaction between torque transferring elements a second, adjacent blade, to rotate in an opposite direction, causing a third blade, adjacent the second blade, to rotate in the first blade's direction, and transferring torque from the first to the third blade by means of a link member. This arrangement reduces the effect of play between torque transferring elements and reduces the complexity in mounting and operation of a damper.
