Abstract

A filter module is provided with a filter housing provided with an inflow opening. A filter element with an annular filter medium body with an elongate cross-sectional shape is arranged inside the filter housing. A flow path is defined between the inflow opening of the filter housing and an inflow side of the filter medium body. A swirl device is arranged in the flow path and impresses a swirl onto an incoming fluid. The swirl device is a part separate from an outer wall of the filter housing. The swirl device is arranged axially upstream of the inflow side of the filter medium body. The swirl device is provided with a displacement body arranged inside the filter housing adjacent to the inflow opening. The displacement body forms a flow guiding element.
