摘要：
A charge fan assembly is located behind the forward operator cab and draws air from about the top of the PPU and a portion of an airflow from the charge fan assembly is directed downwardly into the crossflow cleaning fan assembly. A pair of closely spaced-apart sheets create a venturi and speed up the charge fan airflow into the crossflow cleaning fan and impact the crossflow cleaning fan at an angle where the blades of the crossflow cleaning fan are widely open. The exhaust air from the crossflow cleaning fan is nearly the same across the entire lengthwise extent of the crossflow cleaning fan.
