AIR FILTER COMPRISING A PREFRACTIONATOR

摘要

The filter has a prefractionator comprising an air outlet configuration that corresponds with a filter surface of a filter element (1). The prefractionator has a cyclone arrangement with individual cyclones (140) comprising a flow path (148). A receiver of an air filter housing is designed to receive the filter element in a form of multi-bellows filter that comprises inner filter bellows (20) and exterior filter bellows (10). A part of the individual cyclones is aligned with the flow path on a line corresponding to an inflow channel of the filter element.
