There is provided a filter for filtering particles in a container of fluid. The filter comprises a flow director comprising a hub, a plurality of radial blades extending from the hub and a plurality of vanes concentric about the hub. The blades and the vanes intersect to form a grid which collectively define a plurality of openings, each opening extending between a first face and a second face, where a cross-sectional area of each opening decreases from the first face to the second face. The filter further includes a skirt coupled to the perimeter of the flow director for maintaining the flow director in spaced relation from a bottom of the container. The decrease in cross-sectional area of the openings in the grid helps to prevent particles from travelling from a position below the flow director to a position above the flow director.

The present invention relates to a filtering panel (100) for a disk filter and a disk filter for water purification, comprising a metal filter cloth (16, 116) such as a stainless steel filter cloth, pre-tensioned in both warp and weft directions and fastened to a frame (10, 110) comprising a peripheral portion (11, 111), which is integral with an inner grillwork (12) and which divides the inner area of the peripheral portion (11, 111) into fields (15, 115). The frame (10, 110) comprises a plastic material reinforced with glass fibers or carbon fibres such as polypropylene loaded with fibreglass in an amount of at least 20 weight percent. Each field of the grillwork (12, 112) has an area not exceeding 10% of the inner area of the peripheral portion (11, 111). The pre-tensioning of the filter cloth (16, 116) in both directions is from at least 20% of the yield stress of the cloth (16, 116). Further the present invention relates to a disk filter comprising said filtering panels (100) and method of making said filtering panel (100).

A filter element sensor module having a housing, a sidewall of the housing including a recessed portion. The sensor module including a sensor assembly being provided within the housing about a sensor port interface being provided at one end of the housing. The sensor module also including processing circuitry being configured to receive signals from the sensor assembly and communication module, the communication module being configured to transmit one or more sensed parameters from the sensor assembly.

The present invention relates to a suction filter unit (1) for filtering liquids. The filter unit (1) comprises: a housing element (3) with an open first side and an open opposing, second side, the housing element (3) comprising a first set of filter element supporting elements (23); a first cover (5) sealingly connected to the first side of the housing element (3); a second, different cover (7) sealingly connected to the second side of the housing element (3), the second cover (7) comprising a second set of filter element supporting elements (25); a filter unit inlet (9); a filter unit outlet; a first filter element (13) for providing a fine filtering property of the liquid; and a second filter element (21) arranged between the first filter element (13) and the inlet (9) for providing a coarse filtering property of the liquid. The second filter element (21) is clamped between the second cover and the housing element (3) by the first and second set of filter element supporting elements (23, 25).

Filtration media, media packs, and filtration elements are described, including fluted filtration media having offset flutes arranged to intermittently contact flutes on adjacent media, including angled and curved flutes. Pleated filtration media with alternating sealed pleat edges are also disclosed, including fluted media with alternating sealed flutes. A media pack can have a first sheet of media and a second sheet of media. The first sheet of media can have a first plurality flutes defining first flute valleys extending between a first face and a second face of the media pack. The second sheet of media can have a second plurality of flutes defining second flute peaks extending between the first face and the second face of the media pack. The first plurality of flutes can be non-parallel to the second plurality of flutes, and each first flute valley contacts one second flute peak at a discrete contact point.

A filtration device for filtering cooking oil is provided. The filtration device may include a hub and one or more filtration units having a central aperture to coupleably receive the hub. Each of the one or more filtration units may include a first upper filter sheet including a water insoluble or partially water insoluble material or combination of materials that convert or at least partially convert free fatty acid in the cooking oil to soap and a second upper filter sheet arranged adjacent to the first upper filter sheet and coupled thereto. The second upper filter sheet can include a material or combination of materials that remove or at least partially remove the soap from the cooking oil to produce filtered cooking oil. The one or more filtration units can be in fluid communication with the hub through which filtered cooking oil may be removed from the filtration device.
