Abstract: According to the present disclosure, features, components and techniques useable for providing air cleaner arrangements are provided. Many of the features relate to an axial seal arrangement provided on a filter cartridge. A typical filter cartridge, for use with these features, is a filter cartridge having opposite flow ends. Example media arrangements that fit this characterization are described. Seal arrangements provided with an axial housing sealing engagement surface are shown. A seal arrangement is provided with variations therein, to advantage. These variations can be in either or both of an outer peripheral edge surface and a housing seal engagement surface. Also, air cleaner assemblies having advantageous features therein are provided. Further, air cleaner housings are described, with selected, preferred features for engagement with filter cartridges.

Abstract: The disclosure concern air cleaners. Preferred air cleaners are shown which include a housing and a removable and replacement primary filter cartridge. Optional and advantageous features are shown. An optional mechanical interlock, operated with a non-threaded, movement of the cartridge, is provided between the primary filter cartridge and the housing. The preferred primary filter cartridge is conical in shape. A preferred optional safety or secondary filter cartridge is shown. Preferred methods of assembly and use are provided.

Abstract: An air intake arrangement for an air intake system for an engine includes a first pre-cleaner arrangement having a housing with an air flow inlet to receive air to be pre-cleaned. A pre-cleaner region is constructed and arranged to remove at least some particulate from the inlet air. The first pre-cleaner arrangement further includes a vacuum flow path and a drop tube flow path. The vacuum flow path is in air flow communication with a first vacuum source to selectively put a vacuum draw through the pre-cleaner region. The drop tube flow path is in air flow communication with a drop tube to eject particulate removed from the inlet air by the pre-cleaner region.
