FILTER MEDIA ARRANGEMENT, FILTER CARTRIDGE, AND METHODS

摘要

A filter arrangement includes a layer of media and a layer of woven wire screen secured together into a media/screen construction, in which there are corrugations and pleats angled relative to the corrugations. Either only the screen is corrugated, or both the media and screen are corrugated. The filter media arrangement is useable in a filter cartridge. A method of making a filter media arrangement includes providing a sheet of flat filter media; securing a wire screen to the filter media to create a media/screen construction; corrugating the at least the wire screen; and pleating the media/screen construction angled to a direction of the corrugations.
