Filter Element, Filter Housing of an Air Filter and Air Filter

A filter housing of an air filter

• wherein the filter housing is openable for installation of at least one filter element therein;
• wherein the filter housing as at least one inlet for air to be purified and at least one outlet for purified air;
• wherein at least one filter element is installable into the filter housing, the at least one filter element including:
• at least one filter medium for filtering air, which at least partially surrounds an element interior of the filter element with respect to an element axis;
• wherein the filter element replaceably arranged within in an openable filter housing having at least one inlet for air to be purified and at least one outlet for purified air in such a way that said filter element separates the at least one inlet from the at least one outlet;
• wherein the filter element has at least one element-side support element on an outer side facing away from the element interior on at least one end face which is axial with respect to the element axis;
• wherein the support element includes
• at least one element supporting portion, which, at least in the installed state of the filter element in the filter housing, has a surface contour deviating from a flat surface on its end face facing away from the element interior;
• wherein at least one housing supporting portion is arranged on the side of the filter housing, which housing supporting portion, at least in the installed state of the at least one filter element in the filter housing, has a surface contour deviating from a flat surface on at least one end face which faces the filter element axially with respect to a housing axis, which housing axis extends parallel or axially to the element axis when the air filter is installed.

An air filter, comprising:

• a filter housing, the filter housing openable for installation of at least one filter element therein;
• wherein the filter housing as at least one inlet for air to be purified and at least one outlet for purified air;
• wherein the at least one filter element is replaceably installed into the filter housing, the at least one filter element including:
• at least one filter medium for filtering air, which at least partially surrounds an element interior of the filter element with respect to an element axis;
• wherein the filter element replaceably arranged within in an openable filter housing having at least one inlet for air to be purified and at least one outlet for purified air in such a way that said filter element separates the at least one inlet from the at least one outlet;
• wherein the filter element has at least one element-side support element on an outer side facing away from the element interior on at least one end face which is axial with respect to the element axis;
• wherein the support element includes
• at least one element supporting portion, which, at least in the installed state of the filter element in the filter housing, has a surface contour deviating from a flat surface on its end face facing away from the element interior;
• wherein at least one housing supporting portion is arranged on the side of the filter housing, which housing supporting portion, at least in the installed state of the at least one filter element in the filter housing, has a surface contour deviating from a flat surface on at least one end face which faces the filter element axially with respect to a housing axis, which housing axis extends parallel or axially to the element axis when the air filter is installed.
