  • NOZZLE FILTER
    Publication number: 20190111394
    Abstract: Devices and methods for the filtration of particulates from a liquid stream are provided. A filter cartridge includes a housing configured to be placed in-line with a stream of liquid and a plurality of hollow fiber filter members disposed within the housing. The hollow fiber filter members are potted at one end of the housing and configured to capture particulates from the stream of liquid via surface energy. The filter cartridge can provide low pressure loss filtering and is capable of being placed within a small space.
