Abstract
A system for aspirating a pre-cleaner of a work vehicle may include a fluid conduit in flow communication with an outlet port of the pre-cleaner for receiving an aspirated airflow from the pre-cleaner. The system may also include a double-walled flow pipe having an inner tube that receives a primary fluid flow of the work vehicle. The double-walled flow pipe may also include an outer tube surrounding the inner tube such that an annular passage is defined between the inner and outer tubes. The annular passage may be in flow communication with the fluid conduit. When a vacuum is applied to the annular passage, the aspirated airflow may be drawn through the fluid conduit from the pre-cleaner and directed to the annular passage. The aspirated airflow flows through the annular passage as the primary fluid flow is being directed through the inner tube.
