Abstract
A filter bag pressure vessel having a filter bag that affords significantly more filter area than the conventional filter bag per equal unit area of volume displacement. The arrangement incorporates a center feed that permits a positive 360.degree. sealing of the inlet and filter bag between two parallel surfaces with a single sealing means that eliminates close tolerances and other requirements that were utilized in the prior art constructions. In addition, the filter bag and supporting structure can be adapted to fit within existing pressure vessels.
