Abstract
The present disclosure relates to a filter assembly including an outer housing, and a removable filter insert that fits within the housing. The filter insert includes a generally cylindrical filter element. An insert body is connected to the filter element. The insert body includes a top end cap in which a top end of the filter element is potted, and a bottom end cap in which a bottom end of the filter element is potted. The insert body also includes a cylindrical liner or wall that surrounds the filter element. The cylindrical liner is spaced-apart from the filter element such that an annular flow passageway is defined between the cylindrical liner and the filter element. The outer wall is configured to prevent contaminants from escaping from the filter insert and contaminating the inside of the housing.
