Filter element and filter assembly having two filtration zones

摘要

A filter element (28) may include filter media (48) having an elongated hollow passage (31) extending along a longitudinal axis and between a first end (30) and a second end (32), with the filter media having an exterior surface (33). The filter element may also include first and second fins (44, 46) associated with and extending radially from the exterior surface of the filter media. The filter media may include a first filtration zone (50) extending partially around the hollow passage and between the first fin and the second fin, with the first filtration zone being associated with a first portion (52) of the filter media. The filter media may also include a second filtration zone (54) extending partially around the hollow passage and between the first fin and the second fin, with the second filtration zone being associated with a second portion (56) of the filter media.
