1. A filter cartridge comprising:
- (a) an elongated fluid-conducting core means;
(b) a plurality of filter cells mounted generally parallel to and spaced from one another and radially about the core means, each filter cell having an exterior, the exterior communicating with the interior through a filter medium for filtering fluids which pass from the exterior to the interior of the filter cell, and the interior of the filter cell being in fluid communication with the core means;
(c) at least one filter cell separator mounted radially about the core means between two adjacent filter cells and generally parallel thereto;
(d) said filter cell separator comprising;
a continuous web;
a plurality of rings extending from one side of said continuous web, said rings being in spaced relation with each other;
a plurality of radial ribs extending radially from the inner portion of said web to the outer portion;
said rings coacting with the adjacent filter cell to position said filter cell separator relative to the adjacent filter cell; and
said ribs coacting to form radial fluid pathways for liquid across the external surfaces of said adjacent filter cell.

Abstract
A depth-type filter cartridge comprises an elongated fluid-conducting core, and a plurality of filter cells mounted generally parallel to one another along the length of the core. Fluid to be filtered passes from the exterior into the interior of the cells through a filter medium, and then from the interior of the cells into the core. Support for the filter cells to prevent distortion or damage when used under extreme conditions is provided by external filter cell separators which coact with the cells and are mounted radially about the core between each pair of adjacent cells.
