A versatile compact air precleaner, air cleaning method and disposable air filter cartridge for air precleaner for separating heavier-than-air particulate debris from debris laden air to provide a clean airflow, wherein a flow path for air passing through a separator chamber of the air precleaner is retroflexed en route to the outlet. A plurality of independently rotatably adjustable housing sections of a housing provide utility with multiple clean air outlet configurations, freedom of direction of ejection of particulate debris from the ejector ports, different inlet configurations, mounting of the precleaner from different sides, accommodation of different sizes of filters, and different clean airflow rate capabilities. A separator chamber end section including the ejector ports is connected to the filter as a removable, disposable air filter cartridge to obviate ejector port clogging with change of filters.

1. A versatile compact air precleaner for separating heavier-than-air particulate debris from debris laden air to provide a clean airflow, the air precleaner comprising: a flow path extending through the air precleaner from an inlet to an outlet, a motor-driven fan with a fan blade to draw particulate debris laden air into the inlet and flow the debris laden air along the flow path, a separator chamber, air flow management structure positioned along the flow path at an inlet side of the separator chamber to rotate the particulate debris laden air drawn into the inlet about a longitudinal axis of the precleaner to form a rotating air flow that centrifugally separates and stratifies the particulate debris laden air within the separator chamber such that the heaviest particles of the debris collect in outermost orbits of the rotating air flow, at least one ejector port through which the particulate debris laden air containing the heaviest particles is ejected from the separator chamber to an outside of the air precleaner, and an end wall that closes the separation chamber at an end opposite the inlet in a direction of the longitudinal axis, the end wall being part of an end section of a replaceable air filter cartridge, the end wall causing the flow path for air passing through the separator chamber that has not been ejected as part of the particulate debris laden air ejected from the at least one ejector port to be retroflexed en route to and out of the outlet. 2. The air precleaner of claim 1, further comprising the replaceable air filter cartridge which forms an inner wall of the separator chamber for filtering air from the innermost orbits of the rotating flow en route to the outlet. 3. The air precleaner of claim 2, wherein the separator chamber includes a separator chamber end section including the end wall and at least one ejector port, the separator chamber end section being connected to one end of the replaceable air filter cartridge. 4. The air precleaner of claim 1, wherein the airflow management structure includes a plurality of stationary vanes in a downstream portion of the separator chamber for maintaining said rotating flow of debris laden air in the separator chamber. 5. The air precleaner of claim 1, including a housing having a plurality of housing sections arranged sequentially along said axis and means for releasably connecting and adjustably rotating the sections with respect to one another about said axis, the inlet, the outlet and the at least one ejector port being located in respective housing sections. 6. The air precleaner of claim 5, further comprising at least one mount for mounting the air precleaner on a support, the at least one mount being located on at least one of the housing sections other than said housing sections having said outlet and said at least one ejector port. 7. The air precleaner of claim 1, wherein the airflow management structure includes a plurality of stationary vanes. 8. The air precleaner of claim 1, wherein the motor-driven fan has a motor which is located in the flow path downstream from the separator chamber. 9. The air precleaner of claim 1, wherein the airflow management structure supports the motor-driven fan. 10. The air precleaner of claim 9, wherein the airflow management structure includes a shroud on which the motor driven fan is supported, the shroud tapering outwardly with respect to said axis downstream of the fan blade. 11. The air precleaner of claim 1, wherein the air precleaner is elongated in the longitudinal axis, the inlet and the at least one ejector port are located at opposite ends of the air precleaner and the outlet is located intermediate said ends. 12. The air precleaner of claim 1, wherein the at least one ejector port is located along an outer wall of the separator chamber. 13. The air precleaner of claim 1, wherein the fan blade of the motor-driven fan is located in the flow path upstream of the separator chamber and the motor of the motor-driven fan is located in the flow path of the retroflexed air flow downstream of the separator chamber. 14. The air precleaner of claim 1, wherein: the outlet is located between the inlet and the ejector port in a direction along the longitudinal axis thereby causing the flow path for the air passing through the separator chamber to be retroflexed en route to the outlet. 15. The air precleaner of claim 1, wherein the end section of the replaceable air filter cartridge includes the ejector port. 16. The air precleaner of claim 1, wherein: the replaceable air filter cartridge includes an air filter element defining a longitudinally extending internal passage; anda flow path for air entering the separator chamber though the inlet flows in a first direction; anda flow path for air flowing in the internal passage after passing through the air filter element flows in a second direction opposite the first direction.
