摘要：
A cleaning system for a combine harvester includes a fan, at least one duct having an interior passageway that is positioned to receive an air stream from the fan, and a surface defined within the interior passageway of the at least one duct that is configured to restrict a volume of the flow of air passing through the at least one duct and increase a pressure of the air stream passing through the duct.
