Abstract

A cartridge filter has a unitary upper fitting and a separate gasket which permits a single base filter to be used with a wide range of tube sheet openings, simply by selecting the appropriate gasket. In one embodiment, the gasket is bonded to the unitary upper fitting. In another embodiment, the tubular side wall of the unitary upper fitting defines an annular step, and the gasket defines a bottom edge, at least a portion of which rests on the step.

Abstract

The present device is a detachable core for use with a cylindrical filter cartridge. The core includes a wire frame including at least two vertical struts oriented along a longitudinal direction. The wire frame includes an upper ring and a lower ring mounted to the distal ends of the vertical struts and further includes an upper flange and a lower flange mounted to the upper and lower rings respectively, wherein the lower flange is detachably mounted to the lower ring. Preferably the lower ring includes a gap in the lower ring to enable resilient compression of the ring by squeezing the lower ring in a radial inward direction prior to engagement with the lower flange. Preferably the cartridge filter includes elastomeric end caps and the cooperating rings and flanges are non-circular such that the elastomeric end caps conforms to the non-circular shape of the upper and lower flanges.
