The present invention provides a fan for moving air or transporting lose material. The fan comprises an inlet suction pipe that is bifurcated to form two pipes that then open out into a cone, after which there is a fan-blade wheel. This fan-blade wheel is driven by a drive shaft that passes through the cone and out in the area between the pipes. The drive shaft is driven directly by a motor or through a belt or gear-train drive system. |
