ABSTRACT:
A filter element adapted to be precoated with a filter medium, having a porous tubular core, and a means supporting the filter medium precoat including a discontinuously slotted sheet arranged concentrically about the tubular core. Each of the slots has an elongated configuration, and provides an absolute particle retention ability of less than 50 microns while reducing gas entrapment in the filter element.
According to an additional embodiment of the invention, the filter element includes a porous tubular core, a means for supporting the filter medium precoat terminating a distance from an end of the tubular core so that a relatively low bubble pressure element section is defined, and a discontinuously slotted sheet means positioned over the relatively low bubble point pressure element section and sealed to the precoat support means. Additional embodiments include a vent sleeve having an aperture positioned over the discontinuously slotted sheet means, wherein the slotted sheet means is a band or disc of slotted sheet material.
