A filter body is provided with a filter medium that has filter layers arranged one over the other, wherein each filter layer is provided with at least one active material. The at least one active material is the same in all of the filter layers. The filter layers are to be flowed through serially in a through-flow direction of the filter body. Sensor devices are provided, wherein each sensor device is arranged between two of the filter layers neighboring each other, respectively, so that the sensor devices, in the through-flow direction of the filter body, are arranged one after another in order to determine a sorption capacity of the at least one active material of each filter layer over a service life of the filter body.

Filter body, filter element, and filter assembly

A filter element is provided with a filter medium body that is a folded filter of filter paper. The filter medium body has an inflow side and an outflow side. A sealing element is arranged on the filter medium body. At an end edge face, the filter medium body has an adhesive bead filling at least partially intermediate fold spaces at end edges of the folds. The filter medium body has a lateral band adhesively connected to and covering the end edge face positioned at an angle relative to the inflow and outflow sides. The lateral band is connected to end edges of the folds at the end edge face and extends all the way to the inflow and outflow sides. The lateral band has at least one leg resting on the inflow side or the outflow side adjacent to a rim area of the filter medium body.

Filter element, in particular for gas filtration

The invention relates to a filter element and filter system for filtering a fluid. The filter element () includes at least one, in particular flat filter bellows () made of a filter medium () having an intended raw side () and an intended clean side () situated opposite thereof. A flatly affixed sideband () is disposed at the front faces () surrounding the filter bellows (). A circumferential seal () is disposed at an outside of the sideband (). The sideband () has a flap () projecting over the clean side () of the filter bellows (), the flap () being arrangeable at the front faces () in a V-shaped back-folded manner over the seal ().
