An air precleaner for centrifugally ejecting heavier than air particulates from an airstream for use in an apparatus having an air intake includes a hood having an opening through which air enters the precleaner. A vane assembly includes a centrally positioned dome, a collar encircling the dome and a plurality of vanes each being connected at an inner end to the dome and at an outer end to the collar. Each vane is angled in relation to a horizontal plane. The vane assembly further includes a horizontal wall extending radially outward from the collar. An impeller assembly is rotatably mounted to the vane assembly. Also provided is a base on which the vane assembly is supported via the horizontal wall. The hood, the vane assembly and the base are secured to each other and the air exits the precleaner through the base.
