Filter for cleaning a fluid

A filter for filtering a fluid, the filter comprising:

• a filter housing;
• a filter element arranged in said filter housing;
• a cyclone preseparator arranged upstream of said filter element in a flow direction of a fluid to be cleaned, wherein the fluid to be cleaned is guided through said preseparator to said filter element;
• wherein said cyclone preseparator comprises a plurality of cyclone cells fitted into an intake wall of said filter housing, a first portion of said cyclone cells having a larger diameter than a second portion of said cyclone cells, said second portion of cyclone cells having a smaller diameter relative to said first portion,
• wherein said larger diameter cyclone cells are positioned sequentially aligned along a first axis on said filter housing intake wall,
• wherein said smaller diameter cyclone cells are positioned along a second axis on said filter housing intake wall, said second axis positioned in a traverse direction to said first axis,
• wherein said smaller diameters cyclone cells arranged on said traverse second axis are inserted into niches in said intake wall between said adjacent larger diameter cyclone cells or between one larger diameter cyclone cell and a sidewall of said filter housing, and
• wherein a free flow cross-section of one of said larger diameter cyclone cells is at least twice as lame as a free flow cross-section of one of said smaller diameter cyclone cells.
