Filter element and filter system

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

• a filter housing;
• and
• a filter element arranged exchangeably in the filter housing between a raw side of the filter system clean side of the filter system;
• the filter element comprising a frame and at least one filter bellows arranged in the frame, wherein the at least one filter bellows comprises 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, and wherein the at least one second inflow surface is separate from the first areal inflow surface;
• the filter housing comprising a first inlet for the first fluid flow of the fluid communicating with the first areal inflow surface and at least one second inlet for the second fluid flow of the fluid communicating with the at least one second inflow surface;
• a flow channel extending from the at least one second inlet of the filter housing to the at least one second inflow surface and configured to guide the second fluid flow of the fluid to the at least one second inflow surface;
• the flow channel comprising a raw-side flow channel section, wherein the raw-side flow channel section is arranged inside the filter element, wherein the raw-side flow channel comprises at least one flow deflection for the second fluid flow of the fluid between the at least one second inlet and the at least one second inflow surface, and wherein the at least one flow deflection is a flow reversal.
