Abstract
A filter system using a filter cartridge adapted for disposal in an environmentally acceptable manner. The filter cartridge has no metal parts, and thus avoids the use of a metal center tube, or a center tube of any configuration. The housing itself carries a permanent center tube. A sealing arrangement formed between the filter cartridge and the housing provides a radial seal isolating the outer periphery of the filter cartridge from the remainder thereof. Filter and caps are in the lower pressure downstream zone, and thus any axial forces imposed on the filter place the filter media in tension to avoid the imposition of crushing loads on the unsupported filter.
