Abstract
A filter element that includes a disk-shaped filter medium having an axially upstream surface, an axially downstream surface, and an outer peripheral surface extending axially therebetween. An embodiment of the filter medium has a radial inlet flow surface formed along the outer peripheral surface. Further, there is an inlet flow surface formed along the axially upstream surface, wherein a fluid is able to flow both radially and axially through the filter element.
Claims25
A filter element, comprising:
- a disk of filter medium having an axially upstream surface, an axially downstream surface and an outer circumferential surface extending therebetween, the disk of filter medium having an axial thickness of at least ¼ inch between axial upstream and downstream surfaces and maximum width or diameter, normal to the axial thickness, of at least 12 inches, the filter medium comprising porous chips of fibers bonded together, with a micro-pore structure with an average porosity of less than 0.05 millimeter formed within the porous chips and a macro-pore structure with an average porosity of greater than 0.5 millimeter formed between adjacent chips.
A filter element, comprising:
- a disk of filter medium having an axially upstream surface, an axially downstream surface, and an outer peripheral surface extending axially therebetween, the filter medium having an radial inlet flow surface formed along the outer peripheral surface;
- and an inlet flow surface formed along the axially upstream surface, wherein a fluid is able to flow both radially and axially through the filter element.
