Dual pre-cleaner air filter design

A work machine comprising:

• a frame;
• an engine mounted on the frame, configured to perform work, and including a combustion air intake;
• and
• an air cleaner comprising:
• a container body having a first end and a second end and defining an air flow chamber and a dust flow chamber each defining separate internal cavities within the container body;
• and
• an intake arranged at the first end of the container body and comprising a wall system for receiving air from outside the container body through an inlet in the side of the container body, the intake comprising:
• a dust flow path in fluid communication with and in general alignment with the inlet and extending from the inlet to a dust opening leading to the dust flow chamber;
• and
• an airflow path abruptly and angularly diverging from the dust flow path at a point downstream of the inlet and extending from the dust flow path to an air opening leading to the air flow chamber;

A method of dust removal, comprising:

• directing air from outside a container body having a first end and a second end, through an inlet into an intake arranged at a first end of the container body;
• directing the air from the outside through a wall system of the intake;
• diverging a dust flow path and an airflow path of the air from the outside,
• wherein the dust flow path is in fluid communication with and in general alignment with the inlet and extending from the inlet to a dust opening leading to a dust flow chamber defined by the container body, and
• wherein the airflow path is at a point downstream of the inlet and extends from the dust flow path to an air opening leading to an air flow chamber defined by the container body.
