Abstract

A filter element (10) has a filter bellows (12) arranged about the longitudinal axis (L) and having a first end disk (14) on a first end face (26), and a second end disk (16) on a second end face (28). A central element (20) is arranged rotatably about the longitudinal axis (L) relative to the filter bellows (12) in the interior (18) of the filter bellows (12). The central element (20) has one or multiple positioning elements (22, 24) which interact with counter positioning elements (116, 118) of an upper housing part (114) to fix the central element in the upper housing part (114) in a defined angular position. The central element (20) has at least one electrical connector element (32) on the element, electrically contacting at least one electrical connector element (120) on the housing.
