  • Patent number: 9623355
    Abstract: The present disclosure relates to a filter element that includes a frame and bag-type filter pockets which are connected to the frame. The filter pockets have an inflow side and an outflow side, wherein at least one opening is present on the inflow side for the inlet of a fluid to be filtered by the filter pockets. The interior of each of the filter pockets tapers in the direction of their respective outflow side. Fluid-guiding elements are provided on the inflow and/or the outflow side of the filter pockets. An efficient filter element in which the fluid to be filtered is effectively cleaned is therefore provided.

  • Patent number: 9180394
    Abstract: The invention relates to a multi-layer composite for use in an air filter, comprising at least one upstream ply and a support ply that is connected to the upstream ply. The upstream ply is made of a non-woven fabric and has a finer porosity than the support ply. The aim of the invention is to form and further develop a multi-layer composite for use in an air filter, in particular in a filter bag in such a manner that the upstream ply can be connected in a stable and economical manner to the support ply. The invention is characterised in that the upstream ply is embodied as a spun bonded non-woven, the continuous filaments of which are at least partially twisted or interwoven with the support ply.

  • Publication number: 20150174518
    Abstract: The invention relates to a filter element comprising a frame and bag-type filter pockets which are connected to said frame. The filter pockets have openings on the inflow side for the inlet of a fluid to be filtered into the interiors of said pockets, and the interiors taper in the direction of an outflow side. The aim of the invention is to provide an efficient filter element in which the fluid to be filtered is effectively cleaned, said filter element being characterized in that fluid conducting elements are arranged on the outflow side and/or on the inflow side of the filter pockets.

  • Publication number: 20100119794
    Abstract: The invention relates to a multi-layer composite for use in an air filter, comprising at least one upstream ply (1) and a support ply (2) that is connected to the upstream ply. The upstream ply (1) is made of a non-woven fabric and has a finer porosity than the support ply (2). The aim of the invention is to form and further develop a multi-layer composite for use in an air filter, in particular in a filter bag in such a manner that the upstream ply can be connected in a stable and economical manner to the support ply. Said invention is characterised in that the upstream ply (1) is embodied as a spun bonded non-woven, the continuous filaments (3) of which are at least partially twisted or interwoven with the support ply (2).
