Air filter

An air filter for a fresh air system, comprising:

• a housing including a first housing shell coupled to a second housing shell along an interface;
• an intermediate panel disposed in the housing and separating a crude chamber from a clean chamber in the housing, the intermediate panel including an inside edge delimiting a passage opening and an outside edge defining a periphery of the intermediate panel corresponding to the interface, the outside edge being secured to the housing, wherein the outside edge is spaced apart from the inside edge a distance away from the housing along the periphery of the intermediate panel;
• a filter element arranged in the passage opening and configured to be penetrated by a fluid flow, the filter element including a filter body for filtering the fluid flow;
• and
• a sealing element encompassing a periphery of the filter body;
• wherein the inside edge of the intermediate panel includes a surrounding seal contour being profiled complementary to the sealing element, the sealing element resting against the filter body and the seal contour to define a fluid-tight seal around the passage opening.

An air filter for a fresh air system, comprising:

• a housing having a first housing shell and a second housing shell,
• an intermediate panel disposed therebetween separating a crude chamber from a clean chamber in the housing, the intermediate panel defining a periphery coupled to the housing and including an inside edge delimiting a passage opening;
• a filter element arranged in the passage opening and configured to be penetrated axially by a fluid flow, the filter element including a filter body for filtering the fluid flow;
• a sealing element disposed on and encompassing a periphery of the filter body;
• wherein the intermediate panel includes a seal contour surrounding the inside edge and bordering the passage opening, the seal contour defining a surrounding channel having opposing channel walls, wherein the sealing element rests along the channel and is coordinated with the channel geometrically such that the sealing element engages the opposing channel walls and the filter body to define a fluid-tight seal around the passage opening.

• wherein the inside edge defines a seal contour surrounding the passage opening, and the sealing element interacts with the seal contour and the filter body to define a fluid-tight seal around the passage opening;
• wherein the sealing element is spaced apart from the housing and includes a temperature stability less than a temperature stability of the first housing shell, the second housing shell and the intermediate panel, respectively.
