Various example embodiments relate to rotating coalescers. One embodiment includes a housing comprising a first housing section having a blowby gas inlet structured to receive crankcase blowby gases from a crankcase. The housing further comprises an oil outlet. The rotating coalescer includes an endcap and filter media. The filter media is arranged in a cylindrical shape and is coupled to and positioned between the first housing section and endcap. The filter media is structured to filter the crankcase blowby gases passing through the filter media by coalescing and separating oils and aerosols contained in the crankcase blowby gases. The rotating coalescer includes a hollow shaft extending through the housing and positioned radially inside of the filter media. The hollow shall forms a blowby gas outlet structured to route filtered crankcase blowby gases out of the housing. The rotating coalescer further includes a drive mechanism operatively coupled to the hollow shaft.

A separation assembly comprises a housing, a jet that expels a fluid within the housing, and a turbine assembly positioned within the housing and positioned so as to be contacted by the fluid expelled from the jet. The fluid causes the turbine assembly to rotate about a center rotational axis within the housing. The turbine assembly comprises a first turbine portion and a second turbine portion that are separately formed from each other and attachable together. The first turbine portion comprises a plurality of first vanes and the second turbine portion comprises a plurality of second vanes.

In accordance with an aspect of the present disclosure, an apparatus includes a tubular filter and a motor coupled to the tubular filter. The tubular filter includes a plurality of apertures. The motor rotates the tubular filter about an axis while a differential pressure is applied to an interior space of the tubular filter relative to exterior to the tubular filter. A force is applied, related to the rotation of the tubular filter, to particulate matter agglomerated to an exterior surface of the tubular filter such that the particulate matter is removed from the exterior surface.

A separator as part of a sheet manufacturing apparatus has a mesh drum configured as a cylinder that can rotate and has mesh in at least part of the side; and a case that houses the mesh drum. The case has a supply port and a recovery port that communicate with an inside area, which is the inside of the mesh drum; a discharge port that communicates with a discharge area, which is outside the side of the mesh drum; and an inside wall segregating at least part of the inside area, forming a material recovery area. First screened material is supplied from the supply port to the inside area. In the material recovery area, the separator recovers accreted material, which is first screened material that was supplied through the supply port and accreted on the inside surface of the mesh drum, from the recovery port.

Disclosed herein is an air cleaner capable of being coupled or separated in a vertical direction to improve space utilization. An air cleaner may include a first air cleaning module provided with a first connection unit, and a second air cleaning module detachably coupled to the first air cleaning module and provided with a second connection unit, wherein the second connection unit is configured to be detachably coupled to the first connection unit, and configured to be rotatable with respect to the first connection unit when the second connection unit is coupled to the first connection unit.

Disclosed are a capture device for purifying air, a purification device, and an air purifier. The capture device for purifying air includes: a housing and a capture assembly. The housing is provided with an air inlet and an air outlet, wherein a cavity, in communication with the air inlet and the air outlet, is defined inside the housing; and the capture assembly is arranged in the cavity, and is located between the air inlet and the air outlet. The capture assembly includes a first rotating disk, a second rotating disk and a cylinder, wherein both the first rotating disk and the second rotating disk are rotatable and rotate in opposite directions; and the cylinder is disposed between the first rotating disk and the second rotating disk.

A rotary filter system includes a drive device and a rotary filter device including a filter housing and a filter unit, the filter housing having an inlet and first and second outlets. The filter unit is in the filter housing and completely enclosed by the filter housing. The filter unit has a filter element delimiting a fluid space from a filtrate space, filtrate is discharged from the filtrate space through the first outlet. The filter unit includes a magnetically effective core in a disk-shaped or ring-shaped manner. The drive device has a drive housing in which a stator is disposed to drive the rotation of the filter unit. The stator is a bearing and drive stator which interacts with the magnetically effective core as an electromagnetic rotary drive, so that the filter unit is capable of being magnetically driven without contact and magnetically levitated with respect to the stator.

A rotating separator has a housing preventing separated liquid carryover. A plenum between the annular rotating separating filter element and the housing sidewall has one or more flow path separating guides minimizing the flow of separated liquid to the outlet. The flow path guides may include one or more fins and/or swirl flow dampers and/or a configured surface.

An air filtering device with a replaceable microparticle filter element consists of a rotating blade member, an air filtering panel, a first set of vortex generators, a second set of vortex generators, a receiving channel, and a positioning aperture. The air filtering panel is secured in the positioning aperture that traverses through the rotating blade member. The rotating blade member consists of a fixed end, a free end, a structural body, a top surface, a bottom surface, a leading edge, and a trailing edge. The structural body extends in between the fixed end, the free end, the leading edge, and the trailing edge. Both the first and second set of vortex generators are mounted onto the top surface and along the leading edge for filtering efficiency purposes.
