Abstract: Fluid filtration devices and methods of filtering fluids are described. The devices generally include a housing and an annular filter assembly, wherein the filter assembly is located inside the housing and comprises a filter material. The filter material may be, for example, an electroformed nickel screen having a smooth working surface and expanding pores. A rotating cleaning assembly comprising a distributor and wipers may be located inside the filter assembly.

Abstract: A fluid filtration device is provided that can be used for separating solids from fluids. In some embodiments, the fluid filtration device comprises a hollow housing and a hollow filter assembly located within the housing. Fluid to be filtered is provided to the inside of a filter material in the filter assembly and passes outward toward the housing. In some embodiments one or more flow-directing features are located between the filter assembly and the housing, and may aid in the flow of fluid to a filtered outlet after passing through the filter. The flow-directing features may comprise, for example, channels that extend the length of the filter.
