Abstract
Filters, filter devices including the filters, and methods of using the filters and filter devices, are disclosed.
Claims20
A filter comprising:
- (a) a porous filter element comprising a cylindrical porous metal medium having a hollow interior, a first end, and a second end, the porous metal medium having an inner surface defining the hollow interior of the porous metal medium;
- (b) a first porous metal end cap formed at the first end of the porous metal medium, the first porous metal end cap having an inner surface facing the first end of the porous metal medium;
- (c) a second porous metal end cap formed at the second end of the porous metal medium, the second porous metal end cap having an inner surface facing the second end of the porous metal medium;
- wherein the inner surface of the first porous metal end cap and/or the inner surface of the second porous metal end cap includes a plurality of porous ribs extending from the inner surface toward the hollow interior;
- and/or
- the inner surface of the porous metal medium includes at least one porous rib extending from the inner surface toward the hollow interior.

A filter device comprising
- (a) a housing comprising an inlet and an outlet and defining a fluid flow path between the inlet and the outlet, wherein the filter is across the fluid flow path;
- and
- (b) a filter comprising:
- a porous filter element comprising a cylindrical porous metal medium having a hollow interior, a first end, and a second end, the porous metal medium having an inner surface defining the hollow interior of the porous metal medium;
- a first porous metal end cap formed at the first end of the porous metal medium, the first porous metal end cap having an inner surface facing the first end of the porous metal medium;
- a second porous metal end cap formed at the second end of the porous metal medium, the second porous metal end cap having an inner surface facing the second end of the porous metal medium;
- wherein the inner surface of the first porous metal end cap and/or the inner surface of the second porous metal end cap includes a plurality of porous ribs extending from the inner surface toward the hollow interior;
- and/or
- the inner surface of the porous metal medium includes at least one porous rib extending from the inner surface toward the hollow interior, disposed in the housing across the fluid flow path.

A method of filtering a fluid comprising passing the fluid through a filter comprising:
- (a) a porous filter element comprising a cylindrical porous metal medium having a hollow interior, a first end, and a second end, the porous metal medium having an inner surface defining the hollow interior of the porous metal medium;
- (b) a first porous metal end cap formed at the first end of the porous metal medium, the first porous metal end cap having an inner surface facing the first end of the porous metal medium;
- (c) a second porous metal end cap formed at the second end of the porous metal medium, the second porous metal end cap having an inner surface facing the second end of the porous metal medium;
- wherein the inner surface of the first porous metal end cap and/or the inner surface of the second porous metal end cap includes a plurality of porous ribs extending from the inner surface toward the hollow interior;
- and/or
- the inner surface of the porous metal medium includes at least one porous rib extending from the inner surface toward the hollow interior.
