Abstract
A filter assembly including a replaceable filter cartridge for use with a reusable filter canister. The filter cartridge includes a cylindrical filter media having top and bottom ends respectively mounted within top and bottom end caps. The bottom end cap includes a sidewall that surrounds at least a lower portion of the filter media. A contaminant containment chamber is defined between the sidewall and an outer side of the filter media. When the cartridge is mounted within the canister, the radial sealing element engages an inner surface of the canister to provide a circumferential seal. The sidewall also includes a living hinge positioned below the sealing element.
