Abstract
A flange for a filter insert for separating oil aerosol from air has a flange region with radial contact surface for supporting the flange; an axial first wall region adjoining radially inwardly the flange region; a radial cover region adjoining an end of the first wall region opposite the flange region; a second axial wall region adjoining radially inwardly the cover region and surrounding a central cutout. Radial lifting regions adjoin an end of the second wall region opposite the cover region and extend into the central cutout. First and second wall regions and cover region are concentric to each other. The lifting regions are arranged exclusively in a radially outer region of the central cutout. A coaxial imaginary circle with outer circumference defined by radially innermost points of the lifting regions has a radius of at least three fourths of a radius of the second wall region.
