ABSTRACT:
The invention provides a debris separation-filtration unit comprising a housing; an inlet that receives debris-laden air delivers the air in a tangential, centrifugal airflow-forming manner to the interior of housing; an inner shell that includes a number of airflow passageways; and a debris-capturing filter, the sides of which filter are at least substantially surrounded by the inner shell. Due to the formation of the centrifugal airflow and presence of the inner shell in the housing, only a portion of the debris particles entering the unit come in contact with the filter. The invention also provides debris collection, separation, and filtration systems comprising one or more of the separation-filtration units of the invention; debris collection vehicles comprising one or more of such units or systems; and related methods of collecting, separating, and filtering debris.
