Abstract: A filtering system (10) includes a filtering apparatus having a filter unit for receiving liquid to be filtered, a receptacle for receiving filtered liquid, and an adapter (14) for coupling the filter unit to the receptacle, and also includes a base (12) having a cradle (26) for receiving the filtering apparatus and a base vacuum delivery port (28). The adapter includes an adapter vacuum receiving port (22) coupled to the vacuum delivery port for driving the liquid through the filter and—as filtered liquid—into the receptacle. The cradle and the adapter have an interlocking mechanism (52, 54) that locks the filtering apparatus to the cradle in a locking position in which the vacuum receiving port is sealingly coupled to the base vacuum delivery port. The base vacuum delivery port has a vacuum valve (30) constituted as a normally-closed valve automatically forced open when the filtering apparatus locks to the cradle.

Abstract: A vacuum filter device comprising a filter body having two holders on opposite sides of a filter. Each holder contains a closed container in a fluid-tight, sealed relationship. The filter is retained by a compression sealing element and the sealing element is maintained in place by a compression element formed of a ring. The compression element is bonded to a portion of the body to hold it, the sealing element and filter in place under a compression seal. Optionally a port in the compression element is formed to align with the vent of the device. Further, an alignment feature on the compression element ensures the port is in alignment with the vent of the device. The device also includes a vacuum port communicating with the downstream side of the filter, and hence the filtrate container.

Abstract: A flow diverter, vacuum control and tilting of the liquid filtering system are used alternatively or in conjunction to reduce foam production in a filtered liquid sample. A liquid filtering system includes an upper sample reservoir, a filter and a lower storage bottle. A vacuum is applied below the sample filter to draw sample liquid through the sample filter into the storage bottle. A flow diverter may be used to direct flow of the filtered liquid sample onto a sidewall of the storage bottle or guide flow to a bottom of the storage bottle. The vacuum may be regulated to reduce foaming. The liquid filtering system may be tilted to direct fluid to the sidewall of the lower storage bottle and reduce foaming.

Abstract: A liquid vacuuming and filtering device may include a container having an interior sealed from the ambient, a vacuum pump in communication with the interior, a two-way valve connected to the container interior, a flexible hose connected to the valve, a filter positioned within the container interior and connected to the valve and a standpipe positioned within the interior and connected to the valve. The vacuum pump may be adjusted to a filling configuration in which the pump evacuates the container interior to a pressure below ambient, which causes fluid to be drawn through the hose, valve and through the filter, which may collect particulates that contaminate the fluid. Filtered fluid then collects within the container. The vacuum pump also may be adjustable to a discharge configuration in which the pump pressurizes the interior to a pressure above ambient, wherein the valve is adjusted to allow filtered fluid within the container to flow through the standpipe, valve and be discharged from the container through the hose. The device may be suitable for reclaiming contaminated fluid used in machining operations, oil or coolant reservoirs, cooking oil and the like.

Abstract: An apparatus removes liquid from a liquid and solids mixture. The apparatus may include a bowl-shaped, rigid container having an upper portion, a lower portion, and a sidewall forming a chamber for receiving the liquid and solids mixture. The container includes a plurality of conduits extending radially outwardly along an inner portion of the sidewall. A filter separates the conduits from the liquid solids mixture in the chamber. Means is also provided for reducing pressure in the chamber, which causes at least liquid to be drawn from the mixture through the filter and conduits. Related systems and methods may be follow from use of the apparatus.
