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.
