  • Publication number: 20040134851
    Abstract: Fluid filtration devices that include nylon membranes are provided according to the present disclosure that maintain thorough wetting of a membrane through the end cap bonding process. The fluid filtration device typically includes a pleated microporous nylon filter media and polypropylene end caps. The pleated microporous filter media is treated with hydrophilic polymeric surface treatments at the ends thereof prior to contact with molten polypropylene end caps, thereby maintaining the ability to integrity test the filtration device in water. Exemplary polymeric surface treatments include solutions and dispersions of polyvinyl alcohol, polyethyleneimine, a combination of 1-4 butanediol diglycidyl ether and ethylene amine, and a quaternary amine polyepichlorohydrin.

  • Publication number: 20040060858
    Abstract: A filter element is disclosed that includes a filtration media, an upstream pleat support and a multi-layer downstream pleat support. The multi-layer downstream support includes a first downstream support layer and a second downstream support layer. The first downstream support layer is in contact with the filtration media and is interposed between the filtration media and the second downstream layer. The first downstream support layer is fabricated so as to minimize points of surface contact with the filtration media, thereby enhancing fluid flow away from the filtration media. The second downstream support layer is in contact with the first downstream support layer and is fabricated so as to facilitate lateral fluid flow relative to the multi-layer downstream pleat support. The disclosed filter element may be utilized in filter cartridges of various designs to provide enhanced filtration performance, e.g., by way of increased media area and improved flow/throughput.
