FILTER ELEMENT WITH CENTRAL ELEMENT FOR A FILTER SYSTEM

The invention relates to a filter element (10) for filtering a fluid, having a longitudinal axis (L), which comprises a filter bellows (12) arranged around the longitudinal axis (L) with a first end disc (14) at a first end face (26) and a second end disc (16) at a second end face (28), as well as a central element (20) arranged in the interior (18) of the filter bellows (12) around the longitudinal axis (L) and rotatable relative to the filter bellows (12). The central element (20) has one or more positioning elements (22, 24) which, upon proper assembly, are provided to cooperate with one or more counter-positioning elements (116, 118) of a housing upper part (114) of a filter housing (110) of a filter system (100) in order to fix the central element in the housing upper part (114) in a defined angular position relative to the one or more counter-positioning elements (116, 118). The central element (20) has at least one element-side electrical connection element (32) which is provided in the filter housing (110) for electrical contacting of at least one housing-side electrical connection element (120). The invention further relates to a filter system (100) with such an exchangeable filter element (10).
