Abstract

The invention relates to a filter element ( 10 ), including a filter body ( 12 ) with a self-contained exterior side ( 50 ) which surrounds a self-contained interior side ( 52 ), at least one filter medium ( 16 ) being disposed between exterior side ( 50 ) and interior side ( 52 ) and the filter body ( 12 ) including at least in some areas at least one winding layer ( 14 ) with at least one adsorbent. The invention relates furthermore to a filter system ( 100 ) with a filter element ( 10 ) with a filter body ( 12 ) with a self-contained exterior side ( 50 ) which surrounds a self-contained interior side ( 52 ), at least one filter medium ( 16 ) being disposed between exterior side ( 50 ) and interior side ( 52 ), the filter body ( 12 ) including at least in some areas at least one winding layer ( 14 ) with at least one adsorbent.

First claim

What is claimed is:

1 . A filter element comprising:
a filter body having a closed outer face, which surrounds a closed inner face; wherein the inner face encloses a central flow chamber; wherein at least one filter medium is situated between the outer face and the inner face; and wherein the filter body including, at least in sections, a wound layer having at least one adsorbent.

2 . The filter element according to claim 1 , wherein
the filter body includes a carrier body onto which a layer having at least one adsorbent is applied, and the carrier body, by winding up the carrier body, obtains a substantially circular cross section.

3 . The filter element according to claim 1 , wherein
the wound layer has a sealing at its edges.

4 . The filter element according to claim 1 ,
wherein the sealing forms an end plate located at the end face.

5 . The filter element according to claim 1 , wherein
the filter body is fluidly coupled with at least one particulate filter.

6 . The filter element according to claim 1 , wherein
the filter body is fluidly coupled with at least one aerosol filter.

7 . The filter element according to claim 1 , wherein
the filter element is designed substantially housingless so that the filter element includes a through-flowable outside.

8 . The filter element according to claim 1 , wherein
the at least one adsorbent includes at least one material from the group of activated carbon, zeolites, silica gels, metal oxides, molecular sieves, phyllosilicates and nanoclays.

9 . The use of a filter element according to claim 1 , wherein
the filter element is a cabin air filter of a motor vehicle.

10 . The use of a filter element according to claim 1 , wherein
the filter element is an air filter in a fuel cell system.

11 . An arrangement of filter elements, including:
at least two filter elements according to claim 1 fluidly connected in series.

12 . The arrangement according to claim 11 , wherein
one or a plurality of filter elements are configures and adapted to be fluidly connected then disconnected as needed.

13 . A filter system comprising:
a filter element including:
a filter body having a closed outer face, which surrounds a closed inner face;
wherein the inner face encloses a central flow chamber;
wherein at least one filter medium is situated between the outer face and the inner face; and
wherein the filter body includes at least in sections, a wound layer having at least one adsorbent.

14 . The filter system according to claim 13 , wherein
the filter element is designed substantially housingless so that the filter element includes a through-flowable outside.
