Airflow control device (1) for use in an air handling system, which comprises an outer tube (2) and at least one inner tube (3) arranged inside the outer tube (2). The inner tube (3) is at least partly made of flexible material and has an axial opening (4) through which air is adapted to flow. The inner tube (3) further exhibits an inlet part (8) and an outlet part (10), and a throttle part (9) between the inlet part and the outlet part. The device (1) is characterized by a pivotable throttling device (7) which is arranged to impact the inner tube (3), and thereby control the airflow through the inner tube (3), by rotation around a second pivot axis (b). |
