Abstract
The specification and drawings disclose a fluid filter device which includes a central body section clamped between a pair of end fittings by a plurality of longitudinally extending tie bolts. The tie bolt arrangement is such that only one bolt must be removed to permit the central body section to be swung out of position between the end fittings for filter cleaning, changing, or the like. The central body section includes a cylindrical through passage which extends longitudinally of the body perpendicularly to end faces which mate with the end fittings. A filter cartridge is received in the through passage and includes a cylindrical sleeve which is sized so as to be closely and slidably received in the passage. Filter elements are mounted within the sleeve. Additionally, seal rings are carried about the opposite ends of the sleeve to provide a fluid seal between the end fittings and the central body, as well as to prevent leakage between the outside of the sleeve and the wall of the passageway.
