Abstract

An extended area filter is provided. The extended area filter has sheets of a filter media configured for increased filter media surface area. A plurality of filter media tubes are position in a concentric arrangement about a longitudinal axis of the filter, defining annular inlet volumes and annular outlet volumes, the annular inlet volumes receiving an unfiltered fluid, and the outlet volumes receiving a filtrate passed through the tubes of filter media. Internal support elements suitable for placement within the outlet volumes are also provided. A filter apparatus configured for filtering a contaminated fluid and employing extended area filters of the invention is also provided.
