Filter device for filtering a fluid

A filter device, comprising:

• a filter element including at least one pleated filter medium;
• wherein the at least one filter medium includes a top side and a bottom side;
• at least one strainer arranged on the side of the top side, the at least one strainer extends parallel to the filter medium and includes a strainer material having multiple passages;
• wherein the filter device includes at least one bypass spaced apart from the at least one filter medium;
• and
• wherein the filter element includes a frame that receives the at least one filter medium, and the at least one bypass is formed in the frame.

A filter device for filtering a fluid, comprising:

• a flat filter element extending flat in a longitudinal direction and a transverse direction running transversely to the longitudinal direction, the filter element including at least one pleated filter medium through which a flow path of the fluid leads in a height direction running transversely to the longitudinal direction and transversely to the transverse direction;
• wherein the at least one filter medium, in the height direction, includes a top side and a bottom side facing away from the top side;
• at least one strainer arranged on the top side, the at least one strainer extends flat parallel to the filter medium and includes a strainer material having multiple passages opened in the height direction such that the flow path leads through the strainer in the height direction;
• wherein the filter device includes at least one bypass spaced apart from the at least one filter medium in the longitudinal direction and through which the flow path leads in the height direction;
• wherein the filter device further includes a housing upper part and a housing lower part located opposite the housing upper part in the height direction, the housing upper part and the housing lower part delimit a volume in which the flat filter element and the at least one strainer are received;
• at least one connector disposed on a side of the housing upper part facing away from the volume in the height direction, the at least one connector is fluidically connected with the volume and through which the flow path leads;
• and
• wherein the at least one connector is inserted into the at least one bypass such that the flow path in the height direction leads through the connector and the bypass.
