Abstract
Converting machines give rise to polluted air which must be removed with the aid of fans and filters. The invention aims at removal of the polluted air in such a way that the servicing interval is greatly extended by the use of a filter unit having a number of part-filters arranged one after the other and formed of pleated fiber mats, the various mats having different filtering properties.
