Abstract:
Eine Filtereinrichtung weist in einem Gehäuse ein Filterelement und stromab des Filterelements eine Abströmöffnung zur Ableitung des gereinigten Mediums auf. Zwischen dem Filterelement und der Abströmöffnung ist ein Umlenkteil angeordnet, wobei am Umlenkteil ein Überströmbereich für die Strömung des Mediums von dem Filterelement zur Abströmöffnung gebildet ist und die Abströmöffnung auf gleicher Höhe oder unterhalb des Überströmbereichs liegt.

Filter media (10, 100) and a method (75) for manufacturing filter media (10, 100) is disclosed. The filter media (10, 100) includes a corrugated porous filter media layer (16) including a top surface (16a) and a bottom surface (16b), wherein the corrugated porous filter media layer (16a) includes one or more peaks (22) separated by valleys (24), a second porous filter media layer (18) including a top surface (18a) and a bottom surface (18b), the valleys (24) of the corrugated porous filter media layer (16) proximate the second porous filter media layer (18), and an ultrasonically weldable material (20, 102) disposed between one or more of the valleys (24) of the corrugated porous filter media layer (16) and the top surface (18a) of the second porous filter media layer (18).
Abstract:
Fluid treatment arrangements and elements and methods for making and using fluid treatment arrangements and elements are disclosed. A ribbon including a permeable fluid treatment medium may be spirally wound in a plurality of windings to form a fluid treatment element having a disk-shaped body. At least two and as many as many as fifty or more fluid treatment elements may be positioned along a core assembly with spaces between at least some of the adjacent fluid treatment elements to form a fluid treatment arrangement. For some embodiments, fluid flowing between the exterior of the fluid treatment arrangement and the interior of the core assembly may flow through a permeable fluid treatment medium having a first fluid treatment characteristic and a permeable fluid treatment medium having a different second fluid treatment characteristic. For some embodiments, fluid flowing between the exterior of the fluid treatment arrangement and the interior of the core assembly may flow through a fluid treatment element having a first fluid treatment characteristic and a functional material having a different second fluid treatment characteristic.
Abstract:
Fluid treatment arrangements and elements and methods for making and using fluid treatment arrangements and elements are disclosed. A ribbon including a permeable fluid treatment medium may be spirally wound in a plurality of windings to form a fluid treatment element having a disk-shaped body. The disk-shaped body may have first and second opposite end surfaces, e.g., an inflow surface and an outflow surface, and an outer rim. One or both of the end surfaces may be an uneven surface. At least two and as many as many as fifty or more fluid treatment elements may be positioned along a hollow core assembly. Fluid may be directed to or from the interior of the core assembly through each fluid treatment element. In each fluid treatment element, fluid flows from the inflow surface to the outflow surface generally edgewise through the permeable fluid treatment medium.
Abstract:
Fluid treatment arrangements and methods for making and using fluid treatment arrangements are disclosed. A ribbon including a permeable fluid treatment medium may be spirally wound in a plurality of windings to form a fluid treatment element having a disk- shaped body. The disk-shaped body may include opposite end surfaces, an inner rim, and an outer rim. Up to one hundred or more fluid treatment elements may be positioned along a core assembly, and a surround may be positioned around the fluid treatment elements. The fluid treatment elements may be sealed to the core assembly with the inner rims covering openings in the core assembly, or the fluid treatment elements may be sealed to the surround with the outer rims covering openings in the surround. A fluid treatment arrangement may be contained in a housing to form a fluid treatment assembly. The housing may include an inlet port and an outlet port and may define a fluid flow path between the inlet port and the outlet port. The fluid treatment arrangement may be positioned in the housing across the fluid flow path.

Fluid treatment arrangements and elements and methods for making and using fluid treatment arrangements are disclosed. A ribbon including a permeable fluid treatment medium may be spirally wound in a plurality of windings to form a fluid treatment element having a disk-shaped body. For some embodiments, the ribbon may comprise a composite having first and second layers. Up to one hundred or more fluid treatment elements may be positioned along a core assembly with spaces between at least some of the adjacent fluid treatment elements. Posts may be located in some of the spaces and may be bonded to the adjacent fluid treatment elements. Bands may encircle some of the spaces to block radial fluid flow into or out of the spaces. A fluid treatment arrangement may be contained in a housing to form a fluid treatment assembly. The housing may include an inlet port and an outlet port and may define a fluid flow path between the inlet port and the outlet port. The fluid treatment arrangement may be positioned in the housing across the fluid flow path.
