Filter element and filter system

A filter element for filtering a fluid, the filter element comprising:

• at least one filter bellows comprising a first areal inflow surface for a first fluid flow of the fluid and at least one second inflow surface for a second fluid flow of the fluid separate the first fluid flow of the fluid, wherein the at least one second inflow surface is separate from the first areal inflow surface, and wherein the at least one filter bellows defines a flow direction;
• a continuous frame molded circumferentially around the at least one filter bellows;
• a flow channel section for the second fluid flow of the fluid;
• and
• at least one compensation element arranged in the flow channel section for the second fluid flow of the fluid at a raw side of the filter element;
• wherein the at least one compensation element is flowed through by the second fluid flow of the fluid in a direction other than the flow direction;
• and
• wherein the at least one compensation element is connected to the continuous frame and to the at least one filter bellows.

A filter system for filtering a fluid, the filter system comprising:

• a filter housing;
• a filter element for filtering the fluid arranged exchangeably in the filter housing between a raw side of the filter system and a clean side of the filter system;
• the filter element comprising at least one filter bellows comprising a first areal inflow surface for a first fluid flow of the fluid and at least one second inflow surface for a second fluid flow of the fluid separate from the first fluid flow of the fluid, wherein the at least one second inflow surface is separate from the first areal inflow surface;
• the filter housing comprising a first inlet for inflow of the first fluid flow of the fluid to the first areal inflow surface and at least one second inlet for inflow of the second fluid flow of the fluid to the at least one second inflow surface;
• at least one compensation element arranged at the raw side of the filter system upstream of the at least one second inflow surface;
• and
• a flow channel for the second fluid flow of the fluid extending through the at least one compensation element from the at least one second inlet for inflow of the second fluid flow of the fluid to the at least one second inflow surface;
• wherein the at least one compensation element is arranged at an angle relative to the at least one second inflow surface;
• wherein the at least one compensation element is flowed through by the second fluid flow of the fluid in a direction other than the flow direction;
• and
• wherein the at least one compensation element is connected to the at least one filter bellows.
