Abstract

A filter cartridge is structured of a filtration mat assembly wrapped or rolled about a central distribution tube. The filtration mat includes a plurality of hollow porous fiber strands carried by a fluid permeable sheet. Once the mat has been wrapped about the porous central distribution tube, both ends of the mat and distribution tube are firmly embedded in end caps. The central distribution tube is comprised of two tube segments which are telescopingly connected. Shrinkage and contraction or swelling and elongation of the mat's fibers cause the end caps to move toward or away from each other. This movement of the end caps is able to occur due to the ability of the telescoping central distribution tube to decrease or increase in length.
