摘要:
Damper of a ventilation duct, which damper comprises a hollow duct part (1), e.g. a cylindrical pipe, a turnable plate (2) inside it for adjusting the airflow, a shaft (3) fixed to the plate, and also an adjusting means, such as a turnable wheel (5), fixed to one end of the shaft outside the duct part for turning the damper plate manually. The invention is implemented so that a control handle (7) provided with an insulation allowance can be installed on top of the turnable wheel (5).
