20100018914 | VAULT FILTER - A filter system includes a plurality of filter assemblies coupled to a common receiving chamber. Each filter assembly is arranged so that filtered water can flow into the receiving chamber under the influence of gravity and pressure from the difference in water level on the outside of the filter assemblies and the water level within the receiving chamber as maintained by a drain or pump within the chamber. Each filter assembly includes an upright intake tube having inlet openings spaced vertically along the intake tube. A filter housing surrounds each intake tube and is spaced from the intake tube by a distance sufficient to receive a filter element between the intake tube and the housing. A cap secures the top of the filter assembly so that all water passing into one of the inlet tube openings must have first passed through the housing and the filter element. Blocking devices are used to change one filter element while the filter system continues to operate via the other filter assemblies. | 01-28-2010 |
20120000843 | INVOLUTE CARTRIDGE FILTER SYSTEM - A fluid filter system including a filter housing having an inlet chamber that surrounds the inner chamber that houses the filter cartridges. The filter cartridges are positioned in an involute configuration to channel rotationally inward flow of the fluid as it loses kinetic energy and velocity. The configuration provides superior filtering of fluids flowing therethrough and provides superior filter life. | 01-05-2012 |
20120097598 | SEQUENTIAL FILTER PACK FOR FLUIDS - The present invention relates to a filter pack formed by stacking rings, being used as a final element in multistage or single-stage filters. The filtration process is performed by consecutively separating the particles in suspension according to the thickness thereof in different areas. | 04-26-2012 |
20130048552 | FILTER DEVICE AND FILTER ELEMENT PROVIDED THEREFOR - The invention relates to a filter device, in particular for fluids polluted with admixtures of water, such as diesel oil, comprising a filter housing ( | 02-28-2013 |
20130062273 | Enhanced Filter Support Basket - A filtration vessel is provided with improved sealing surfaces and alignment methods. The sealing surface is provided by a perforated sleeve within the filtration vessel. An alignment mechanism is provided which allows for improved servicing of the filtration vessel. | 03-14-2013 |
20130112611 | DISC SHAPED FILTER ELEMENT - The invention relates to a disc shaped filter element for filtering a liquid such as a polymer. The filter element comprising—a hub, said hub defining a central opening therethrough,—an upper filter medium and a lower filter medium, said upper filter medium and said lower filter medium extending radially outwards from said hub. The upper filter medium and the lower filter medium comprise a layered structure comprising a first layer and a second layer. The first layer comprises a non-sintered metal fiber fleece and the second layer comprises a layer of non-sintered metal powder particles. The first layer and the second layer are sintered together. | 05-09-2013 |
20130256213 | FILTRATION SYSTEM AND COMPONENTS THERE FOR - A filtration array comprising a main raw fluid supply line and a main filtered fluid collecting line, at least one filtration flow path extending between the main raw fluid supply line and the main filtered fluid collecting line; each of the at least one filtration flow path is configured with a filtering assembly comprising a pair of filter units coaxially extending from a common manifold configured on the filtration flow path and is in flow communication with the main raw fluid supply line and the main filtered fluid collecting line, each of the filter units comprising a plurality of parallely disposed filter members. | 10-03-2013 |
20130270171 | FILTRATION SYSTEM AND ASSEMBLY THEREOF - A filtration system comprising a tank-like housing, accommodating a filtration assembly secured within the housing and extending between a respective raw fluid inlet port and a filtered fluid outlet port. The filtration assembly comprises one or more filter units secured over a main pipe disposed within the housing and configured between a fixed, operative position, and a manipulating position. The housing is configured with at least one re-sealable opening on a side wall thereof, through which the filter units are serviced at the manipulating position. | 10-17-2013 |
20160000052 | BIOCHEMICAL BALL - A biochemical ball includes a first half, a second half, and a plurality of sponge filters. The first half has a plurality of first ribs, a first rim, and a first partition. The first partition divides the first half into a plurality of equal first accommodating spaces. The first rim of the first half is provided with a first fastener and a connecting joint. The second half has a plurality of second ribs, a second rim, and a second partition. The second partition divides the second half into a plurality of equal second accommodating spaces. The second rim of the second half is provided with a second fastener configured to correspondingly engage with the first fastener. The sponge filters are so received in the first and second accommodating spaces that the sponge filters are separated without contacting each other, thereby enhancing filtering efficiency. | 01-07-2016 |
