Abstract: A filter module includes an axially extending central channel, a first hollow adapter having an interior through which the central channel extends, a second hollow adapter having an interior through which the central extends, one or more filter cells positioned between the first and second adapters and around the central channel, and an enclosure. The enclosure has a first retainer ring mounted around the first adapter, a second retainer ring mounted around the second adapter, and an envelope which is sealed to the first and second retainer rings and extends around the one or more filter cells.

Abstract: The present invention relates to a filter module comprising a body of wound layers of a sheet material, said sheet material having a plurality of openings formed therein, said openings forming two types of channels within the wound layers of sheet material of said body, said channels extending in a direction from the inner peripheral surface to the outer peripheral surface, a first type of channels being open at one end at said outer peripheral surface of the body and closed at the other end located adjacent to said inner peripheral surface, a second type of channels being open at one end at said inner peripheral surface of the body, and closed at the other end located adjacent to said outer peripheral surface, said channels of the one type being separated from the channels of the other type by portions of sheet material, wherein the sheet material has areas at the edge of the openings forming the inlet channels the thickness of which being smaller than the thickness of the sheet material remote from those op

Abstract: The invention concerns a module for filtering media. More particularly, the invention concerns a module for filtering fluids and including one or more filter cells stacked on top of one another. The invention also relates to an installation set for the installation of at least one such filter module in a filter housing, as well as to a filter device with a filter housing, in which the filter module or the filter modules is/are installed together with the installation set.

Abstract: A filter module is formed of wound filter material having openings wherein the boundary surfaces of the openings constitute flow-through surfaces. The openings of the wound layers of the filter material form channels angled relative to the winding axis, wherein one group thereof opens at the outer peripheral surface of the roll and the other group opens at the inner peripheral surface of the roll and wherein the channels on the other end, respectively, are closed and wherein the channels, angled relative to the winding axis, are separated from one another by filter material, and wherein the inner area of the roll has a central channel arranged around a winding axis.

Abstract: A filtration device for filtration, comprising at least one filter unit in a closed filter housing, comprises at least one filtration station and a loading and removing station. The filter housing can be opened in at least one parting plane transversely to the longitudinal axis of the filter housing and is movable between the loading and removing station and the filtration station.

Abstract: The invention relates to a filter module, whose casing unit comprises a media-tight sleeve (30, 30)′ and two retaining rings (32, 34, 34)′, the sleeve (30, 30)′ being fixed to the retaining rings (32, 34, 34′) in a media-tight manner and each retaining ring (32, 34, 34′) being mounted on an adapter (24, 26, 26′). The sleeve (30, 30′) consists of a flexible and/or elastic material. Said sleeve prevents a contamination of the filter housing. The invention also relates to an installation kit for installing at least one filter module of this type in a filter housing and to a filter device.

Abstract: The invention relates to a filter module (1) comprising filters layers (4a, b) made of a filter medium, especially comprising filter layers made of filter strata. Said filter layers alternate with layers made of draining spacer elements 910, 10a, b, 20), the first and last layer of the filter module (1) consisting respectively of a draining spacer element (10a, b, 20). The draining spacer elements respectively and mutually comprise flow elements (12a, b) and sealing elements (11a, b) for the filtrate chamber and the non-filtrate chamber (40, 41). Means are provided for the mutual connection thereof The aim of the filter module (1) is to combine the advantages of known filter modules with improved sealing at the edges of the filter layers, and to make the filter module backwashable. The filter module (1) comprises draining spacer elements (10, 10a, b, 20) which are embodied in such a way that they enable the filter layers to be pressed in a sealing manner.

Abstract: A process for treating cooling lubricants to prevent attack by microorganisms using crospovidone-iodine as biocidal substance, wherein the cooling lubricant to be treated is brought into contact with a filter cake which consists essentially of particulate crospovidone-iodine as filter medium.
