SEPARATOR FOR CELL TYPE FILTER CARTRIDGES

摘要

Applicants: OSTREICHER et al. Title: IMPROVED SEPARATOR FOR CELL TYPE FILTER CARTRIDGES The present invention sets forth an improved cell type filter cartridge in which the individual cells contain a separator disc having stiffening members formed at the central aperture of the cell and connected to a plurality of the separating ribs in spaced relation to each other. The coaction of the two or more discs with the separator ribs provides for a rigid, box-like structure of the ribs to impart a substantial cantilevered strength to the ribs. Additionally, at least one of the stiffening discs is positioned at or near the ends of the separator ribs to act as a load-bearing surface to prevent media intrusion of the filtering medium and thereby maintain the area of the flow path of the filtered liquid as it passes through the central aperture of the disc.
