A circulating oil stream cleaner wherein oil to be cleaned is passed through filter medium to remove particulates carried by the circulating oil and through an evaporator unit having a flat, inclined, evaporation surface comprising a top surface of a heat conductive heating block with an electric heater probe therein and positioned closely beneath the heating surface and, with the circulating oil being conductively heated as it passes beneath the heating block, up a frontal end of the heating block and cascades onto and spreads as a film over and then off the heating surface of the heating block through an exit port of the evaporator unit; an evaporation chamber provided above the heating surface allows heated air to circulate over and convectively heat the film of oil and to escape with entrained water and volatiles.

The invention relates to a filtration system for use in a method of determining the presence and/or amount of cells, for example, viable cells, in a liquid sample, and to methods of using and manufacturing such a filtration system. The filtration system includes a cup with an upper portion and a ring portion, where the ring portion is separably coupled to the upper portion.

An apparatus and a method are provided for an application specific fuel filter that is configured to prevent particulates from entering the fuel system of a motor vehicle, the fuel filter comprising a hollow canister comprising a length and diameter; a first end comprising a fuel inlet; a second end comprising a fuel outlet; a filter element comprising a plurality of pleats; and a rolled seam.

A filter insert, a sample vial incorporating a filter insert, a method of using a sample vial containing a filter insert for chemical analysis, and a sample vial kit including a filter insert. The filter insert includes a cylindrical body having a proximal end, a protrusion extending radially from the proximal end of the cylindrical body and configured to set on the open end of a sample vial, a distal end, a cavity extending longitudinally through the cylindrical body from the proximal end to the distal end, and a filter assembly coupled with the distal end of the cylindrical body.

A liquid filter assembly comprising a filter subassembly is inserted within an elongated tubular filter body, enclosed by a pair of end caps. The filter subassembly includes a plurality of filtration discs placed onto a tubular core and inner support member. A disc aperture is provided concentrically through each filtration disc. An outer filter support member and a central filter support member support each filtration disc. The outer filter support member engages with an interior of the elongated body and an end wall engages with the disc perimeter. The central filter support member engages with an exterior of the inner support member and an end wall engages with the peripheral edge about the filtration disc aperture. Fluid passes through the first end cap orifice, continuing through the inner support member, transferring flow through the filtration discs, returning through the inner support member, and exiting the opposite end cap orifice.

The present invention provides a filter member. The filter member comprises: a filter for discriminating cells to be analyzed in a sample from other components; a first filter holding member which comprises a first through hole and has a plate-like shape; and a second filter holding member which comprises a second through hole and is fitted into the first filter holding member. When the first and second filter holding members are integrated by fitting the second filter holding member into the first filter holding member, the filter is sandwiched between the first filter holding member and the second filter holding member, and the first through hole is opposed to the second through hole through the filter. A first elastic body is formed on a surface of the first filter holding member, the surface being in contact with the filter. A second elastic body is formed on a surface of the second filter holding member, the surface being in contact with the filter.

A replaceable subsea filter uses a hot-stab style connection. The filter has a flow path located along a central axis. At a distal end of the of the filter, the flow path locates inside a subsea receptable, typically associated with a reservoir or sea chest for a hydraulic actuator. At a proximal end, the flow path opens into an annulus around the stab-connecter, the annulus being separated from the surrounding waters by annular filters.

A water pump and a filter assembly for the water pump. The water pump includes a water tank, a pump body with a water inlet located at the bottom of the water tank, and a filter assembly having a connecting opening, surrounding and connected to the water inlet of the pump body through the connecting opening, so that the water in the tank enters the pump body after being filtered by the filter assembly. The filter assembly is arranged in the water tank, and even if the filter assembly is clogged due to long-term use and ineffective cleaning, the water will not overflow from the water tank, thereby avoiding economic losses or safety hazards caused by water overflow. Further, the water pump and the filter assembly for the water pump have the advantages of simple structure, easy production and manufacturing, and economic benefits.
