Abstract
A filter for liquid or gaseous media has a cylindrical form in the closed position and a curved form in the open position. The filter includes a frame and at least one filter element arranged on the frame. Two circumferential ends of the frame are provided with fixing elements for fixing to each other in the closed position. In a plurality of first sections of the frame the frame has a first wall thickness. In a plurality of second sections of the frame the frame has a second wall thickness less than the first wall thickness. The wall thicknesses are measured in the radial direction in the closed position of the filter, respectively with a second section between two first sections.
