摘要：A filter element has a filter body having a longitudinal axis, wherein the filter body has a first end with a first end face and a second end with a second end face opposite the first end in direction of the longitudinal axis. The filter body is provided with inner and outer circumferential surfaces permeable for a medium to be filtered. A first end disk is arranged at the first end face and a second end disk is arranged at the second end face. The outer circumferential surface of the filter body has at least one fluid-tight area that is impermeable for the medium to be filtered. The fluid-tight area is an incoming flow protector or an improper handling protector resting on the outer circumferential surface.

主权项：1. A filter element comprising: a filter body having a longitudinal axis, wherein the filter body has a first end with a first end face and a second end with a second end face opposite the first end in direction of the longitudinal axis,wherein the filter body is provided with an inner circumferential surface and an outer circumferential surface that are permeable for a medium to be filtered; a first end disk arranged at the first end face; a second end disk arranged at the second end face; wherein the outer circumferential surface of the filter body has at least one fluid-tight area that is impermeable for the medium to be filtered; wherein the fluid-tight area is formed by an incoming flow protector and/or an improper handling protector resting on the outer circumferential surface; wherein the incoming flow protector and/or the improper handling protector comprises a flexible film applied onto the outer circumferential surface of the filter body.
