Claim 0:
1. A fluid filtration assembly, comprising:
a housing having a thickness defined between an internal surface of the housing and an external surface of the housing, the housing extending in an axial direction from a first end to a second end, the external surface defining an outer diameter of the housing, the outer diameter remaining constant from the first end to the second end;
a first filter having a first radially outer surface and a first radially inner surface, the first filter disposed in the housing, the first radially outer surface and the internal surface of the housing defining an outer annular flow passage;
a cavity disposed radially inward of the first filter;
an inlet pipe in fluid communication with the outer annular flow passage, the inlet pipe disposed at the first end, the inlet pipe disposed substantially tangentially to the internal surface of the housing;
an outlet pipe in fluid communication with the cavity to discharge the fluid from the housing, the outlet pipe disposed at the first end; and
a collection area disposed at the second end of the housing, the collection area configured to collect particulate matter from the fluid, wherein:
the fluid is configured to flow radially from the outer annular flow passage through the first radially outer surface of the first filter and the first radially inner surface of the first filter into the cavity,
the fluid is configured to flow axially from the cavity out the outlet pipe, and
in response to injecting the fluid substantially tangentially to the internal surface of the housing through the inlet pipe, the particulate matter is forced against the internal surface of the housing within the outer annular flow passage, wherein the thickness of the housing gradually decreases towards the collection area.
