  • Publication number: 20200376425
    Abstract: A filter element has a filter bellows of filter medium laid into folds. The folds extend between oppositely positioned end edges of the filter bellows, respectively. The end edges form oppositely positioned end edge surfaces. The filter bellows is arranged in closed configuration about a longitudinal axis and encloses a hollow space. The filter bellows has opposed end faces sealed by an end disc. The filter bellows has a cut portion in at least one of the oppositely positioned end edge surfaces such that one or more regions of folds with shortened fold length are formed. A fold length of the folds with shortened fold length is substantially identical at an outer and inner circumference of the filter bellows. A filter system has a housing in which the filter element is arranged. One of the housing parts has a region corresponding to the cut portion of the filter bellows.
