Abstract

A filter cartridge includes a substantially cylindrical filter media and a pressure relieving structure. The filter media is adapted to allow fluid to pass from an exterior of the filter media to an interior space of the filter media. The pressure relieving structure is disposed at an upper end of the filter media, and the pressure relieving structure opens when a predetermined pressure level is established across the filter media to maintain the predetermined pressure across the filter media.
