Publication number: 20030226792Abstract: The invention relates to a multi-layer filter element. The invention provides a main filter layer which preferably consists of a melt-blown fleece and has an absolute filtration capability. A paper layer (2) on the clean side supports the filter element and does not contribute to the filtering of the fluid to be filtered. Said layer can therefore have a macropore structure, thereby allowing a low flow resistance. A layer (3)on the clean side which preferably also consists of paper serves to pre-filter the fluid and to protect and support the main filter layer. The inventive design of the multi-layer filter material provides a means for economically producing filter elements, especially filter cartridges which are folded in the shape of a star, since no trellis protective layers are necessary. The invention also facilitates an improved thermal disposability of the proposed filter cartridge.Type: ApplicationFiled: May 20, 2003Publication date: December 11, 2003Applicant: Filterwerk Mann & Hummel GmbHInventors: Manfred Tumbrink, Joachim-Paul Krieger, Gunnar-Marcel Klein

Publication number: 20020056684Abstract: A multi-layer filter element for filtering fluids, in which a plurality of layers of filter media follow each other in succession in the direction of flow through the filter. All of the individual filter layers are preferably made of synthetic fibers, especially polyester fibers. The successive filter layers exhibit an increasing degree of filter fineness in the direction of flow through the filter, and the filter material contains at least one filter layer arranged on the inflow side of the filter which is composed of a meltblown fiber nonwoven web, especially a polyester fiber web.Type: ApplicationFiled: October 19, 2001Publication date: May 16, 2002Inventor: Gunnar-Marcel Klein
