Abstract

A filter is taught having filter elements (33) with flanged ends (35 36) sealed together. The seal may be secured by use of a rod (56) extending in a lengthwise direction through apertures (55) in the flanged ends, the rod having one end releasably securing the filter element and a second end secured to the housing. A frame (101) can cover the filter elements, and a jack screw (107) in the frame can be used to apply force to the filter elements to secure the seals. The filter may have a cleaning apparatus (80) capable of suctioning material from the filter element.
