Abstract

A filter system is provided with a housing having a housing wall and a cover, the housing having a longitudinal axis. An inlet is arranged on the housing and feeds a fluid to be filtered into the housing. An outlet is arranged on the housing and discharges the filtered fluid. Filter elements each having at least one filter medium are arranged in the housing. At least one of the filter elements extends along the longitudinal axis. The filter medium has pleats extending along the longitudinal axis with outer and inner pleat edges. The outer pleat edges extend on the first side of the filter medium and the inner pleat edges on the second side of the filter medium and are opposite the outer pleat edges. The filter medium has a variable flow resistance along the longitudinal axis.
