Abstract
An air cleaner device for filtering intake air including a housing defining a chamber, a filter element disposed within the chamber, and a duct element having a passageway in fluid communication with the chamber. Further, the duct element extends along and downwardly from about a portion of the housing and further includes an inlet for drawing intake air into the chamber. The air cleaner having a base member in fluid communication with the chamber and an outlet, where the air drawn into the chamber is filtered by first and second filtering operations to obtain filtered air, with the first and the second filtering operations accomplished at least in part due to a cyclonic motion of the air and passage of the air through the filter element, respectively; and where the filtered air from the chamber of the housing is released through the outlet in the base member.
