Abstract
A filter element comprising a filter jacket, a fluted filter media, and an internal seal is provided. The filter jacket defines a filter jacket inner surface, a gravitational bottom, an upstream end, and a downstream end. The filter jacket includes a moisture release aperture disposed proximate the gravitational bottom. The fluted filter media resides within the filter jacket and defines a filter media outer surface. The fluted filter media comprises a planar sheet and a fluted material intermittently bonded together and collectively coiled to form a plurality of flutes. First and second selected ones of the plurality of flutes are closed proximate the upstream and downstream ends, respectively. The internal seal is formed between the filter jacket inner surface and the filter media outer surface. The internal seal is disposed within the filter jacket between the upstream and downstream ends. The moisture release aperture is located upstream of the internal seal.
