Abstract

A filter module for a filter assembly has a primary filter element and a secondary filter element. A water separation interface is provided for discharging water, which has been separated by the primary filter element from a fluid to be filtered, from the primary filter element. A primary filter interface is provided for discharging fluid, which has been filtered by the primary filter element, from the primary filter element. A secondary filter interface is provided for discharging the fluid, which has been filtered by the secondary filter element, from the secondary filter element. The water separation interface, the primary filter interface, and the secondary filter interface are arranged coaxially to a symmetry axis of the filter module. The water separation interface, the primary filter interface, and the secondary filter interface are each designed for outflow of material flows in axial direction of the symmetry axis.
