  • Modular filter elements for use in a filter-in-filter cartridge
    Patent number: 8678202
    Abstract: Disclosed are modular filter-in-filter elements, namely an outer filter element and an inner filter element which may be assembled to form a filter cartridge for use in separation methods and systems. The outer filter element typically functions as a coalescing element and the inner element typically functions as a particulate filter element. The disclosed filter cartridges may be structured for separating water from a hydrocarbon-based liquid fuel as the fuel moves through the cartridge from outside to inside.
    Type: Grant

  • Two stage fuel water separator and particulate filter utilizing pleated nanofiber filter material
    Patent number: 8517185
    Abstract: A water separator and particulate filter with a first or outer stage configured to coalesce water from fluid such as fuel, and a second or inner stage configured to separate coalesced water from the fluid and also remove fine solid contaminants from the fluid. The coalescing stage includes a pleated cylinder of polymeric media. The pleated cylinder has pleat valleys and downstream pleat tips, and release sites defined at the downstream pleat tips. The separator stage includes a non-pleated cylinder of polymeric media surrounding and in contact with outer pleat tips of a multi-layer pleated cylinder.
