Round filter element, in particular for gas filtration

A round filter element comprising:

• a filter medium body comprising
• a wall configured to be flowed through by a fluid to be purified in a radial direction relative to a longitudinal axis of the filter medium body,
• wherein the filter medium body comprises
• a first end face and
• a second end face;
• a circumferentially extending seal carrier arranged at or adjacent to the first end face of the filter medium body;
• a sealing element supported at the seal carrier adjacent to a radial outer side of the filter medium body;
• a positioning element extending into the filter medium body and configured to engage with form fit a correlated housing-associated counter positioning element of a filter housing when the round filter element is installed in the filter housing;
• wherein the seal carrier and the sealing element separate flow-tightly a raw side of the round filter element from a clean side of the round filter element when the round filter element is installed in the filter housing;
• an end disk arranged at the first end face of the filter medium body,
• wherein the end disk comprises
• a cutout disposed adjacent to the positioning element and configured to receive the counter positioning element.

A filter device comprising:

• a round filter element comprising:
• a filter medium body comprising a wall configured to be flowed through by a fluid to be purified in a radial direction relative to a longitudinal axis of the filter medium body, wherein the filter medium body comprises a first end face and a second end face;
• a circumferentially extending seal carrier arranged at or adjacent to the first end face of the filter medium body;
• a sealing element supported at the seal carrier adjacent to a radial outer side of the filter medium body;
• a positioning element extending into the filter medium body,
• wherein the positioning element is an elongate body comprising a longitudinal axis extending in the radial direction,
• wherein the positioning element extends radially into the filter medium of the filter medium body;
• a filter housing configured to receive the round filter element and comprising
• a counter positioning element,
• wherein the positioning element of the round filter element is configured to engage with form fit the counter positioning element of the filter housing when the round filter element is installed in the filter housing,
• wherein the seal carrier and the sealing element separate flow-tightly a raw side of the round filter element from a clean side of the round filter element when the round filter element is installed in the filter housing.
