  • the filter medium body can preferably be connected to the receiving pocket on the filter element housing as well as from the receiving pocket without tools or with only a small amount of tool insert.
  • the frame is placed on the receiving pocket, so that the frame surrounds the receiving pocket and surrounds the wall of the receiving pocket.
  • the frame is inserted into the receiving pocket and enclosed by the wall of the receiving pocket.
  • the filter medium body is inserted into the receiving pocket, whereas the frame on the filter medium body engages around the wall of the receiving pocket.
  • the frame is formed circumferentially and thus extends completely over the outer periphery of the filter medium body.
  • the frame only partially revolves and thus only extends over a part of the outer circumference of the filter medium body.
  • the frame on the outer periphery of the filter medium body and the receiving pocket are preferably connected in a flow-tight manner in order to prevent incorrect air flows on the clean side of the filter medium body and to improve the filtration performance of the filter element.
  • At least two receiving pockets are arranged on the filter element housing, which are each assigned a filter medium body.
  • the receiving pockets are preferably located on diametrically opposite sides of the filter element housing.
  • the filter media bodies inserted into the receiving pockets bound each one side of the clean room in the filter element housing.
  • the receiving pockets and the associated filter medium body are preferably located on diametrically opposite sides of the filter element housing, wherein a non-diametrical arrangement is also possible, for example, an angular offset arrangement in, for example, a 90 ° angle.
  • receiving pocket and more than one filter medium body are arranged, they preferably have the same structure, so that all receiving pockets are constructed the same and all the filter medium body including the surrounding frame are the same structure. This applies both to the geometric structure and to the size ratios, although embodiments are possible in which the receiving pockets and the filter medium body or the frame on the filter medium body differ from each other.
  • the frame is fastened by means of a sealing element on the outer circumference of the filter medium body.
