An apparatus operable to separate particulates, as dirt, dust and foreign materials, from air and deliver clean air to the operator\s compartment of a tractor cab. The apparatus has a motor-driven fan which moves air through a chamber surrounded with a cylindrical casing. The air moves through the chamber in a circumferential spiral direction whereby the particulates separate to an annular outside zone. Spaced inclined vanes direct the central core of clean air to a clean air passage and the annular zone of air carrying particulates to an annular air discharge opening. Clean air is directed to a fiber filter which filters fine particulates from the air and disperses the air to the operator\s compartment.

An apparatus for supplying air to a location comprising: a casing surrounding a chamber, said casing having a first end, a second end, and at least one air inlet opening open to the chamber to allow outside air to flow into the chamber; means for covering the first end of the casing, a plurality of stationary inclined vanes located in the chamber secured to the casing, adjacent vanes being spaced from each other to form passages open to the chamber and the second end of said casing, a rotatable fan located in the chamber between the vanes and means for covering the first end of the casing, motor means for rotating said fan whereby air is moved through the air inlet opening into the chamber and through the chamber in a circular path thereby concentrating pArticulates in an outer zone of air moving through the chamber and passages, means mounting the motor means in the central portion of the chamber, and a collar located adjacent the second end of the casing providing a clean air outlet passage and an air discharge opening, said outer zone of air and particulates being discharged through said air discharge opening and the remaining air being discharged through the clean air outlet passage.
