Abstract:
A filter body of an air filter for coupling to a connection element having a supporting contour, the filter body comprising:a) a cylindrical filter element made of filter material; b) an inner frame disposed within said filter element for supporting said filter element radially; and c) at least one end unit coupled to at least one end of said filter material and said inner frame comprising: i) an end disk mounted on at least one axial end of said filter element; and ii) a ring shaped axially extending collar coupled to said end disk, wherein said axially extending collar has an axially elastic section which includes a tapered section that decreases in thickness as it extends axially away from said end plate, a coupling section coupled to said tapered section forming a seal when it engages the connection element and at least one constant section coupled to said coupling section and having a substantially constant thickness, wherein said tapered section extends radially inward towards said coupling section while said constant section extends radially out from said coupling section.
