A filter arrangement for an aquarium is disclosed. The filter arrangement can include a filter housing assembly, a pump assembly, and a transfer tube assembly. In one aspect, the housing assembly and the pump assembly are separately constructed assemblies that are connected to each other via a first dampening member to prevent vibration and sound from being transmitted from the pump assembly to the filter housing assembly. The filter arrangement can further include a second dampening member connecting the pump assembly with the transfer tube assembly to further prevent vibration and sound from being transmitted from the pump assembly to the filter housing assembly. A third dampening member can be provided at a location where the transfer tube assembly is supported within the filter housing assembly to further isolate vibration and sound from being transmitted from the pump assembly to the filter housing assembly via the transfer tube assembly.

A disposable dental waste filter device has a body having a tube receiving end having an outlet and a cap receiving end, a cap portion having an inlet and an end for insertion into the cap receiving end, a valve insert assembly for insertion into the body and the cap portion, and a filter assembly positioned within the body.

Proposed is a non-electric water purifier in which a flow path provided between a water-purifying filter and a water outlet cock is replaced in order to minimize contamination of purified drinking water. The non-electric water purifier includes a main body having a door formed on one side thereof so as to open and close the main body and having and having a receiving space part defined therein, a connector which is coupled replaceably and rotatably to one side of the main body and incudes a raw water passage connected to a raw water inlet and a purified water passage through which purified water flows, at least one filter housing being received in the receiving space part, with a discharge outlet of the filter housing being coupled detachably to the connector, and the water outlet cock which is connected to a discharge opening of the connector and discharges purified water.

Flow control elements (FCEs) and fluid apparatus including the same are described. In embodiments the flow control elements (FCE) include a body that includes a front side, a back side, a left side, and a right side. The body further includes a base region, an upper region, and an intermediate region between the base region and the upper region. The FCE is configured to move in response to a fluid flow (or, more specifically, a pressure differential across the FCE) to regulate a flow of fluid past the FCE. In embodiments the FCE is included in a fluid apparatus for a vehicle, such as but not limited to a suction filter for a vehicle transmission.

A filtered water supply extension system including an extension member and a flow control device, and a method for extending a filtered water supply of a primary appliance, for example, a refrigerator, to an external appliance, for example, a coffee maker, are provided. The extension member draws and directs an additional flow of filtered water from a water filter of the primary appliance to the external appliance, without interrupting a regular flow of filtered water from the water filter to one or more internal appliances, for example, an ice maker, a water dispenser, etc., of the primary appliance. The flow control device connects the extension member to the external appliance and controls the additional flow of filtered water to the external appliance. A microcontroller, in communication with a control panel, controls a valve assembly for directing a measured quantity of filtered water from the water filter to the external appliance.

Disclosed herein is a waste oil purification apparatus that purifies waste lubricating oil and waste oil at high speed by a precipitation induction method in a vacuum state and further completely removes metallic foreign materials, thereby improving the efficiency of the purification of waste oil. The waste oil purification apparatus may include a purifier configured to purify waste oil such as waste lubricating oil or general waste oil by a filtering method, and a separator configured to separate and remove foreign materials contained in the waste oil purified by the purifier.

Some embodiments of the present application disclose a polishing liquid supply system. In the present application, the polishing liquid supply system includes: a polishing liquid preparation device, a cleaning liquid supply device and a filtering device, and further includes a supply pipeline connected with the polishing liquid preparation device and the filtering device and a cleaning pipeline connected with the cleaning liquid supply device and the filtering device. The polishing liquid preparation device is configured to prepare a polishing liquid and convey the prepared polishing liquid to the filtering device through the supply pipeline. The filtering device is configured to filter the polishing liquid and convey the filtered polishing liquid to a polishing device connected with the filtering device. The cleaning liquid supply device is configured to convey a cleaning liquid to the filtering device through the cleaning pipeline.

A removable filter cartridge includes a filter housing containing a filter for filtering liquid and a sealing valve assembly coupled to the filter housing and for removably coupling the filter cartridge to a filter head. The sealing valve assembly include an inlet passageway and an outlet passageway. The sealing valve also including an inlet sealing valve that blocks the inlet passageway and an outlet sealing valve that blocks the outlet passageway while the filter cartridge is uncoupled from the filter head. A method of retrofitting a filter housing includes removing the filter housing from a filter head, coupling a sealing valve assembly to the removable filter to form a removable filter cartridge, and coupling the removable filter cartridge to the filter head.
