Abstract

The invention relates to an arrangement in ventilation systems which includes ducts (1) in which bag-like filters (3) are accommodated. With the intention of balancing the air flows in the ducts, the filters are constructed to generate a high pressure drop and to be throttled individually to achieve a desired air throughflow capacity. Throttling of the filters is preferably effected with the aid of a filter adjustment wire (8) attached to the bottom part (7) of respective filters and by means of which the filter bottom part (7) can be drawn-in to a desired extent into the filter (3).
