Abstract
An air pre-cleaner for centrifugally ejecting heavier than air particulates from an air stream for use in an apparatus having an air intake includes a hood having an opening through which air enters the pre-cleaner. A vane assembly includes a centrally positioned dome, a collar encircling the dome, and a plurality of inlet vanes each being connected at an inner end to the dome and at an outer end to the collar. Each inlet vane is angled in relation to the 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. Clean air exits the pre-cleaner through a central opening in the base and dirty air exits the pre-cleaner through peripheral openings in the base.
