Air cleaner having scavenger arrangement

摘要

An air cleaner construction including a precleaner arrangement, a filter assembly and a scavenger arrangement is provided. In the precleaner arrangement, air directed into the air cleaner assembly is subjected to some particulate removal. The air from the precleaner arrangement is then directed into the filter assembly, for further particulate material. The scavenger arrangement is constructed and arranged to scavenge separated particulate material from both the precleaner arrangement and the filter assembly. A pulse jet cleaner assembly is provided to facilitate removal of particulate material from the filter assembly.
