Filter Device, in Particular for Gas Filtration

A filter device comprising:

• a filter housing comprising a receiving space;
• a filter element arranged in the receiving space in the filter housing, wherein the filter element comprises an annular filter medium body and the annular filter medium body comprises an inflow side;
• the filter housing further comprising a dirt collecting region in flow communication with the inflow side of the annular filter medium body, wherein the dirt collecting region comprises an annular circumferentially extending configuration;
• a flow-tight separation element arranged at or adjacent to the annular filter medium body of the filter element, wherein the dirt collecting region adjoins the flow-tight separation element;
• an inflow region positioned at the inflow side of the annular filter medium body and immediately adjoining the dirt collecting region;
• the dirt collecting region comprising a radial extension in a radial direction, relative to a longitudinal axis of the annular filter medium body, wherein the radial extension of the dirt collecting region is larger than a radial extension of the inflow region.
