<p>A device for controlling airflow between a clean room (1) and an adjacent room (2) is described. Channels (10, 6) lead from the rooms (1, 2) to a common junction (8). A ventilation channel (9) is leading from the common junction (8) for feeding or carrying off air. In the channel (10) from the clean room (1) is included a resistor element for the airflow, while the channel (6) from the adjacent room (2) has low hydraulic impedance.</p> |
