Referring to the figures generally, a rotating filter cartridge includes a first endcap, a second endcap, and a filter media. The filter media is positioned between the first endcap and the second endcap. The filter media creates a mechanical seal between at least one of the first endcap or the second endcap during rotation of the rotating filter cartridge without the use of a potting material. In at least one embodiment, the rotating filter cartridge further includes a body secured to the first endcap and the second endcap. At least one of the first endcap or the second endcap, and the body, may form a pocket that radially pinches the filter media to form the mechanical seal.

Disclosed here is a composite filter media having at least one nanofiber layer bonded to a substrate layer, the at least one nanofiber layer optionally having a plurality of nanofibers having a geometric mean diameter of less than or equal to 0.5 &#x3bc;m, the at least one nanofiber layer having a thickness of about 1-100 &#x3bc;m.

Nanofiber filter media for high performance applications

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.

Disclosed are multiple stage rotating coalescer devices comprising a first stage and a second stage. The first stage may include a rotating coalescing element comprising coalescing media. The second stage is positioned either upstream or downstream or the first stage. The second stage may include one of: (i) a rotating cone stack separator, or (ii) a separate rotating coalescing element comprising coalescing media.

Multiple stage rotating coalescer devices

An internal combustion engine crankcase ventilation rotating coalescer includes an annual rotating coalescing filter element, an inlet port supplying blow by gas from the crankcase to the hollow interior of the annular rotating coalescing filter element, and an outlet port delivering clean separated, air from the exterior of the rotating element. The direction of flow by gas inside-out, radially, outwardly from the hollow interior to the exterior.

An internal combustion engine crankcase ventilation rotating coalescer includes an annular rotating coalescing filter element, an inlet port supplying blowby gas from the crankcase to the hollow interior of the annular rotating coalescing filter element, and an outlet port delivering cleaned separated air from the exterior of the rotating element. The direction of blowby gas is inside-out, radially outwardly from the hollow interior to the exterior.
