A radial fan for an incubator for poultry eggs and newly hatched poultry. The fan has a longitudinally-elongated, hub and a plurality of self-supporting, radially-extending, fan blades on the hub. Each blade is laterally deformable, so that it is deformed by air pressure in a counter-clockwise direction when the hub is rotated in a clockwise direction and is deformed by air pressure in a clockwise direction when the hub is rotated in a counter-clockwise direction.

A harvester cleaning fan system having a cross flow fan rotor, an inlet, an outlet and an inlet cover. The rotor rotates about a fan axis and has vanes defining a cylindrical rotation volume. The inlet extends around the rotor from an inlet leading edge to an inlet trailing edge. The outlet extends from the inlet trailing edge to the inlet leading edge. The inlet cover is adjacent the inlet, radially spaced from the rotor, and extends from a cover leading edge to a cover trailing edge. The cover leading and trailing edges are between the inlet leading and trailing edges. A first inlet passage is between the cover leading edge and the inlet leading edge, and a second inlet passage is between the inlet trailing edge and the cover trailing edge. An agricultural vehicle having a cleaning fan is also provided.
