Zusammenfassung:	A harvester cleaning fan system having a cross flow fan rotor, a fan inlet, a rotor shroud, a fan outlet and a cutoff wall assembly. The fan inlet extends in the fan rotation direction around a first portion of the cylindrical rotation volume. The rotor shroud is adjacent the fan inlet and extends in the rotation direction to enclose a second portion of the cylindrical rotation volume. The fan outlet is adjacent the rotor shroud. The cutoff wall assembly extends in the rotation direction by a cutoff wall distance to enclose a third portion of the cylindrical rotation volume. The cutoff wall assembly has a first cutoff wall and a second cutoff wall. The cutoff wall distance is about 40 mm to about 90 mm, and the fan has a rotation diameter of about 400 mm to about 500 mm. An agricultural vehicle having a cleaning fan is also provided.
