<p>A filter element and filter apparatus, and a method for fabricating a filter element, include a filter element having alternating layers of a face sheet material and a convoluted filter material, with the alternating layers forming substantially longitudinally oriented flutes that extend axially along, or past, a radially acting seal, into previously unused portions of the cavity of a filter housing. In some embodiments, structures such as struts extending partially across an outlet end of the filter element, or a rigid web formed by a layer of resin extending axially a potted length into pome of the flutes from the outlet end resist axially oriented pressure forces on the alternating layers.</p> |
