Abstract: Embodiments provide a filter with a generally rectangular, non-cylindrical profile. The filter may have multiple pleat packs positioned between pleat covers that define regions and flow channels in a cavity of the filter body. The pleat covers have openings that allow a fluid to flow through the multiple pleat packs via parallel flows or series flows. End caps bonded to the body define flow passages for directing the fluid from an inlet to an outlet via the pleat packs for series or parallel filtration. The pleat packs may be made of the same or different materials and may be configured with the same or different heights based on flow requirements. A cage or a separator may be positioned between the pleat packs. The pleat packs may be made of a continuous pleated membrane with bridges defining a space between the pleat packs to accommodate the cage or separator.

Abstract: A filter unit includes a housing, a first filter and a second filter disposed in the housing, and a liquid flow path that extends through the first and second filters in series. The first filter includes a first axial end affixed to the housing and a first filter media. The second filter includes a first axial end affixed to the housing at the outlet and a second filter media. The liquid directed radially outward through the first filter media and radially inward through the second filter media. A method of filtering a liquid within a filter unit includes passing the liquid radially outward through a first filter media of a first filter, directing the liquid from the first filter to a second filter, and passing the liquid radially inward through a second filter element of the second filter.

Abstract: A filter unit for filtering liquid includes a housing with an inlet and an outlet, a first filter and a second filter disposed in the housing, and a liquid flow path extending from the inlet to the outlet. The liquid flow path directs the liquid one of radially inward and radially outward through a first filter media of the first filter and the other one of radially and directs the liquid the other one of radially inward and radially outward through a second filter media of the second filter. A method of filtering a liquid within a filter unit includes passing the liquid one of radially inward and radially outward through a first filter media of a first filter and passing the liquid the other one of radially inward and radially outward through a second filter media of a second filter.
