The present invention discloses a filtering apparatus for filtering liquid and dispensing the filtered liquid into a bottle separate from the filtering apparatus. The filtering apparatus includes an elongated housing having an interior for holding liquid. The elongated housing includes an opening at one end and a ceiling at another end. The opening encompasses projections extending towards the center of the elongated housing. The filtering apparatus includes a filter configured for insertion and removal from the elongated housing. The elongated housing receives the filter at the interior through the opening. The elongated housing receives a bottle at the opening and the projections hold the bottle at the opening while preventing further entry of the bottle into the interior of the elongated housing. The interior holds liquid and allows the liquid to flow down through the filter. The filter filters the liquid as it flows through. The filtered water enters the bottle for subsequent use, storage or transport.

A removable filter cartridge includes a filter housing containing a filter and a sealing valve coupled to an open end of the filter housing. The sealing valve configured to removably couple the removable filter cartridge to a filter head. An open position allows fluid to flow into and out of the internal volume of the filter housing. A closed position seals the filter housing. A method for retrofitting a filter housing includes removing the filter housing from a filter head, coupling a sealing valve to the removable filter to form a removable filter cartridge, and coupling the removable filter cartridge to the filter head.

The present disclosure is directed to a new quick-connect, bayonet-type coupling arrangement for use with connecting a filter cartridge or element to a fluid-consuming machine. Advantageously, the features of the coupling arrangement can be provided while simultaneously maintaining backward compatibility with screw-thread based systems by modifying the screw thread on the end cap so as to include judicially arranged non-interfering segments. Accordingly, the disclosed fluid filter elements can not only be installed on systems according to the present disclosure but also on prior-art systems presenting a thread-based connector.

A spin-on filter assembly with replaceable coreless element comprises: a reusable spin-on housing including a filter bowl having sealing structure on a bottom of the filter bowl and a sealing structure on a top of the filter bowl; a center support tube integral with the filter bowl and including a perforated tube and an upper portion having an threaded coupling allowing for the filter assembly to threaded into position and an exterior sealing structure; and a replaceable coreless filter element mounted on the central support tube within the filter bowl and having filter media, a lower sealing structure configured to engage with the sealing structure on the bottom of the filter bowl and an upper sealing structure configured to engage with the exterior sealing structure on the center support tube.

An immersion bioreactor device may include a vessel coupler, a first vessel, and a second vessel. The first vessel may include a first cavity and a first vessel aperture in fluid communication with the first cavity. The second vessel may include a second cavity and a second vessel aperture that may be in fluid communication with the second cavity. The vessel coupler may be configured to be removably coupled to the first and second vessels so that the first and second vessel apertures are in fluid communication with the vessel coupler. The vessel coupler may include a plate which may separate the vessel apertures from each other. One or more coupler apertures may be disposed in the plate, and the coupler apertures may enable fluid communication between the vessel apertures. Optionally, an adjustable vane disc may govern the fluid communication provided by the coupler apertures.

A fluid filter is mountable on a connection flange having a central stand pipe and an exchangeable filter insert. The insert has a hollow cylindrical filter material body with two end plates on its end faces and is mountable on the stand pipe. A cup-shaped screw housing of the filter can be screwed to a free end of the stand pipe, and supports a seal on a free edge thereof, via which the screw housing is sealable against a connection flange sealing surface when mounted. The filter has a first arrangement on an end face area to center the end face area to the flange. The filter insert has a second arrangement on the end face area outer periphery for centering the screw housing free edge relative to the connection flange sealing surface. The second arrangement interacts in a centering manner with the screw housing free edge when installed.

An adaptor plug for a spin-on fluid filter, in particular for a spin-on return filter, wherein the adaptor plug comprises a plug-in end which is designed to be plugged into a cavity in a flange of a hydraulic device in a fluid tight manner and a filter end which is designed to be connected to the spin-on filter in a fluid tight, detachable manner and at least one internal fluid channel connecting said plug-in end with said filter end, wherein the adaptor plug at its filter end comprises a threaded tube or bolt on which the spin-on filter can be screwed. By this design, the use of a filter set with or without an adaptor ring between the adaptor plug and the filter is enabled. By the adaptor plug, the spin-on filter can be applied to a variety of hydraulic devices, among others, with a ¾ 16 UNF cavity.

A filter element, for use filtering liquids such as fuel, includes a first section of filter media, an optional layer of coalescer media, and a section of barrier media. The first section and optional coalescer filter media are held between opposite first and second end caps. The second end cap is integrated with the barrier filter media. The barrier media extends at least part way into an interior of the first section and can be conical in shape.

A filter adaptor joins a canister filter to a hydraulic manifold block. The adaptor includes a hexagonal tool-receiving portion, an outflow passageway and one or more inflow passageways. The outlet flow passageway extends between opposed ends of the adaptor, and is used to direct filtered fluid from the filter to the manifold block. The inlet flow passageway(s) extend between the one end and a sealed region of the adaptor, and are used to direct fluid from the manifold block to the filter. The adaptor includes auxiliary ports formed in the tool-receiving portion that communicate with the inlet flow passageways and permit monitoring thereof.

A filter comprising a filter housing (10) and a replaceable filter element (12) arranged in the filter housing (10) and having annular upper and lower end members (12a, 12b) and an inner space, wherein the filter housing (10) comprises a housing pot (10a) having a fluid in-let (10e), a fluid outlet and an opening (10b) for inserting the filter element (12). The filter has a support tube (16) extending in the inner space of the filter element (12) and connected to a bottom of the filter housing (10) and a locking member (14), the locking member (14) being adapted to engage the support tube (16) and generate a holding or pushing or pulling force supported on the filter housing via the support tube (16) for holding or pushing or pulling the filter element (12) into or out of the housing bowl (10a).
