ABSTRACT:
A filtration system (10) for removing contaminants from a fluid is provided. The system includes a housing (44) having a convex shaped base (78) and a top (84), with filter media (46) disposed within the housing. The filter media may take the form of a roll having a first end formed by edges of the wound filter media and convex in shape. The system may further include a seal (56) adapted to impede channeling of the fluid in proximity to the core through substantially sealing annuluses formed between adjacent wraps of filter media by engaging the edges of the filter media in proximity to the core without substantially radially displacing the filter media. A fluid passageway may pass through the housing, wherein the passageway (20, 24, 40, and/or42) is sized sufficiently small in cross-sectional area to substantially impede the flow of fluid through the passageway due to gravity.
