ABSTRACT:
An air blower (particularly for agricultural spraying purposes) comprises a fan, an annular fan housing, a curved air deflector downstream of the fan, and a curved air-flow divider. The fan housing has a frusto-conical intake section and a curved outflow section. The outflow section, the air deflector and the air-flow divider each correspond to a surface generated by rotating a curve having a center of curvature C about the axis of rotation of the fan. There is a back plate, the arrangement being such that distance D4 is about half the distance D3. The maximum radial extent of the air-flow divider is less than that of the outflow section and the back plate.
