Abstract
A replaceable element fluid filter is provided that has a rigid apertured center tube which is attached to a fluid outlet. The center tube is formed of a plurality of sections that fit together to achieve the desired overall length. A rod of selectable length is received within the center tube to retain the center tube in rigid position in communication with a fluid outlet. Once the center tube assembly is secured to the fluid outlet, a tubular filter element is replaceably secured around the center tube. By incorporating a rigid center tube, the tubular filter element can be constructed so that it does not require a self contained supporting structure. By varying the number of sections of the center tube and the length of the rod, tubular filter elements of various lengths may be employed.
