A method and an air precleaner for separating heavier-than-air particulate debris from debris laden air to provide a clean airflow are disclosed. A flow path extends through the precleaner from an inlet to an outlet. Debris laden air is drawn into the inlet by a vacuum in communication with the outlet of the precleaner. A vortex flow of the debris laden air is formed in the flow path and flows through a first stage, ejective based precleaner and a second stage, scavenger based precleaner. Each stage centrifugally separates and removes particles of debris from the vortex flow. Efficient operation under extreme conditions with significant improvement in air filter life, is made possible by the air precleaner and method. |
