Filter assemblies are described and shown. Components, features and methods of assembly and use are described. Many of the principles relate to preferred cartridge configurations for engagement with selected housings. Selected optional features described can be used to provide indication to a service provider that a proper cartridge is not positioned appropriately in the housing for use.

Filter systems; components; features; and, methods of assembly and use

According to the present disclosure, arrangements, systems, components, features and methods for filtration are described. The components specifically described include a filter cartridge with preferred features for interaction with a filter housing, and a filter housing with preferred features for convenient installation. Methods of assembly and use are also characterized.

Filter cartridge

According to the present disclosure, arrangements, systems, components, features and methods for separating hydrophobic fluid such as oil entrained as aerosols from gas streams, such as crankcase ventilation gas streams are described. The components specifically described include a filter cartridge with preferred features for interaction with a filter housing, and a filter housing with preferred features for convenient installation. Methods of assembly and use are also characterized.

Air/oil separator assemblies; components; and methods

Crankcase ventilation filter assemblies are described and shown. Components, features and methods of assembly and use are described. Many of the principles relate to preferred cartridge configurations for engagement with selected housings. Selected optional features described can be used to provide indication to a service provider that a proper cartridge is not positioned appropriately in the housing for use.

Crankcase ventilation filter systems; components; features; and, methods of assembly and use

Crankcase ventilation filter arrangements and components therefore are described. Example arrangements are described. In one, a serviceable filter cartridge includes a check valve therein, for protection during vehicle rollover. Handle arrangements are also described. Methods of use are described.

Crankcase ventilation filter assembly; components; and methods

Crankcase ventilation filter arrangements and components therefore are described. Example arrangements are described. In one, a serviceable filter cartridge includes a check valve therein, for protection during vehicle rollover. Handle arrangements are also described. An example filter cartridge is described in which media, surrounding an open interior, is positioned between first and second, opposite, end pieces. A first end piece has a projection on an opposite side from the media, the projection including framework having an upper rail supported by spaced supports. Methods of use are described.
