Flat-filter filter element having at least two filter-material bodies, filter system, and use of a flat-filter filter element

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

• at least two areal filter medium bodies arranged in an axial direction adjacent to each other and arranged to be flowed through by the fluid sequentially in the axial direction;
• wherein the at least two areal filter medium bodies include an outermost downstream filter medium body and an outermost upstream filter medium body,
• a circumferential frame element;
• wherein the outermost downstream filter medium body and the outermost upstream filter medium body are arranged at least partially in the axial direction radially inside the circumferential frame element;
• wherein the outermost downstream filter medium body comprises a circumferential downstream molded element, and wherein the outermost downstream filter medium body is connected by the circumferential downstream molded element to the circumferential frame element;
• wherein the outermost upstream filter medium body comprises a circumferential upstream molded element, and wherein the outermost upstream filter medium body is connected by the circumferential upstream molded element to the circumferential frame element;
• wherein the circumferential upstream molded element is connected to an upstream end of the circumferential frame element and wherein the circumferential downstream molded element is connected to a downstream end of the circumferential frame element.
