Abstract
In one aspect, an air intake system for a work vehicle may generally include a fan shroud, a fan disposed within the fan shroud, an intake duct for receiving a portion of the air drawn through a front grille of the work vehicle by the fan and a filter assembly in flow communication with the intake duct. The filter assembly may include a pre-cleaner defining a scavenge port. The system may also include an aspiration conduit coupled to the scavenge port and an aspiration scoop extending between an inlet end and an outlet end. The inlet end may be coupled to the aspiration conduit. The aspiration scoop may extend through a portion of the fan shroud such that the outlet end is positioned within the fan shroud at a location upstream of the fan. The outlet end may include an outlet opening defined by at least one curved wall.
