Abstract
A side outlet cyclone separator tube having an improved vortex generating device and an air cleaner incorporating the separator tube are disclosed. The tube includes a conduit member which defines a generally axial passageway for the discharge of contaminants from contaminant laden air. A second conduit member is disposed within the first conduit member and defines an outlet passageway for the discharge of clean air through an opening in the side wall of the first conduit member. The improved vortex generating device includes an elongated hub about which are spaced a plurality of generally helical deflecting vanes. A trailing end of the elongated hub has a curved surface which directs contaminants radially toward the inner surface of the first conduit member. The air cleaner has a plurality of side outlet separator tubes aligned in parallel rows, adjacent rows disposed with the side outlets directed toward each other and off-set with respect to the side outlets of the adjacent row to define clean air exhaust channels within the air cleaner housing.
