A hydronic system separator has an air separator with a vent release mechanism to remove air from the fluid within a hydronic system. The separator includes a magnetic assembly for collecting ferrous particles from the fluid. One or more screens are used to remove other particles from the fluid. The separator housing includes a removable debris collection receptacle that has a drain assembly.

A water filtration and recycling system includes an external machine to collect solid particles and water, a first filter to filter the solid particles from the water to form primary filtered water, a second filter to filter the solid particles from the primary filtered water to form secondary filtered water, and a water tank to store the secondary filtered water, wherein secondary filtered water recycles to the external machine in a closed loop. The water filtration and recycling system includes a recycling machine including a clean tank to hold clean water that cycles through the water filtration and recycling system, a dirty tank to hold dirty water that cycles through the water filtration and recycling system, a dirty water in manifold to direct the water into the dirty manifold, a dirty water out manifold to direct the water out of the dirty manifold, a clean water in manifold to direct the water into the clean manifold, and a clean water out manifold to direct the water out of the clean manifold.

An aqueous fluid filter assembly with aeration mitigation includes a cap, a bowl engaging the cap and defining a filter volume, and a filter element disposed in the filter volume. The filter element is sealed against an interior of the cap and an interior of the bowl to provide an unfiltered volume and a filtered volume. An inlet is in fluid communication with the unfiltered volume and an outlet is in fluid communication with the filtered volume via a pickup section. The pickup section has a pick-up section inlet extending into the filtered volume and an air-metering orifice, wherein the air-metering orifice has a diameter less than 30% of the diameter of the pick-up section inlet and the pick-up section inlet is located below the air-metering orifice.

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 fuel water separator comprises a housing that defines an internal volume that receives a mixture. The fuel water separator further comprises a filter element that is positioned within the internal volume. The filter element comprises a first endplate and a second endplate that is located opposite the first endplate. The filter element further comprises a filter media that is coupled to the first endplate and the second endplate. The filter media is structured to separate a dispersed phase from a continuous phase of the mixture. The filter element further comprises a collection sump that is located below the first and second endplate and structured to receive the dispersed phase. The filter element further comprises a retention barrier disposed above the collection sump. The retention barrier comprises a drain opening structured to discharge the dispersed phase through the retention barrier into the collection sump.

A filter element has a filter media assembly extending between a first end and a second end to define a media length along a longitudinal axis. The filter media assembly defines a central opening on an upstream side and an outer radial boundary on a downstream side. A first endcap is coupled to the first end. The first endcap has a media potting structure defining an annular surface abutting the first end of the filter media assembly, an inner tubular flange extending longitudinally from the annular surface into the central opening, and an outer tubular flange extending longitudinally from the annular surface over the outer radial boundary of the first end of the filter media assembly. The first endcap has an outer circumferential sealing surface about the longitudinal axis and a shroud to obstruct fluid flow extending longitudinally from the outer circumferential sealing surface towards the second end.

A filter for filtering fluid has a filter housing with fluid inlet for fluid to be filtered and fluid outlet for filtered fluid. A filter element arranged in the filter housing separates fluid inlet fluidically from fluid outlet. A bypass valve arrangement is arranged fluidically between fluid inlet and fluid outlet such that it fluidically connects in an open state fluid inlet to fluid outlet. The bypass valve arrangement has a valve closure body arranged movably in the valve housing between a closed position and an open position. The bypass valve arrangement has a valve seat element with valve seat. The valve closure body rests sealingly at the valve seat in closed position. The valve seat element is connected to a part of the valve housing by a mechanical connection realized by relative rotation between valve seat element and part of the valve housing about a valve axis.

Proposed is a moisture removal device using a rotating disk and nitrogen peeling according to the present disclosure may include a circulation pump unit for circulating the oil in the storage tank connected to the circulation pump on one side of the device body via a valve, a chamber for exposing the oil circulated through the circulation pump unit into the chamber headspace through the rotation of the plurality of rotating disks, and a membrane unit that supplies dry nitrogen gas to oil exposed in the chamber headspace through rotation of a plurality of rotating disks of the chamber. The moisture removal device may remove free moisture, emulsified moisture, and dissolved moisture in oil contaminated with moisture through dry nitrogen gas purging by using a continuously rotating disk.

In some embodiments, a system for pre-wetting a filter includes a filter, a piping system, a first gas, a second gas, a first buffer tank, and a second buffer tank. The first gas drives the solvent to clean the filter. The two buffer tanks store the solvent discharged from the filter. The second gas selectively drives the solvent in the first buffer tank to return to the filter and then to be discharged into the second buffer tank. Alternatively, the second gas selectively drives the solvent in the second buffer tank to return to the filter and then to be discharged into the first buffer tank.
