Abstract: A filter system for adsorbing an odor of a gas flow in an industrial process includes a filter module (1) with a layer (11) containing active adsorbent (3). The layer (11) includes a plurality of active adsorbent containing permeable bags (2) arranged in close proximity to each other.

Abstract: A method of recycling an saturated adsorbent (3) of a filter module (1) of an industrial process plant (15), wherein a first process (17) includes removing the saturated adsorbent (3) from the filter module (1), a fourth process (20) includes washing and reactivating the saturated adsorbent, a fifth process (21) includes drying and packing the reactivated adsorbent in airtight containers, and a seventh process (23) includes replacing the saturated adsorbent by reactivated adsorbent in the filter module (1).

Abstract: The invention relates to a filter mat, which is used in applications where it filters the flows of contaminated air that pass through it. In such mats, there are points where aerosols collect. This is disadvantageous as it lowers the efficiency of the mat. The present invention overcomes this by having, at these points, wicks (2) that absorb said collections.

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.

Abstract: In a filter unit with a folded filter mat that has spacing devices between parallel opposing parts of the filter mat, the contaminants (e.g. liquids) that have been filtered out collect at the bottom of the unit. The air flowing through the unit is capable of sucking up contaminant liquids so that the air leaving the unit, rather than being clean, contains undesirable, previously filtered contaminants. The present invention reduces such additional contamination by so designing/arranging the spacing devices that they prevent additional contamination being added to the air flowing through the filter unit.
