Abstract

A damper assembly principally for regulating air flow in ventilation plant. It consists of a flow duct (1) and a damper (2) which is rotatable in the flow duct and which is mounted on a removable cleaning plug (3). The cleaning plug (3) is rotatable within and with respect to the duct (1) and the damper (2) is connected with the cleaning plug (3) such that it turns when the cleaning plug (3) is turned. The cleaning plug (3) is provided with a connection piece (8,9) and is rotatable within it (8,9) and also that the connection piece (8,9) can be locked in a fixed position in the duct and furthermore the cleaning plug (3) is lockable in the connection piece (8,9).
