Abstract
A two stage filter device includes a cyclonic pre-separator (10) designed as a pre-filter that separates the particles from the gas flow and a main filter element (20) arranged downstream as a second stage operable to filter by guiding the particles through at least one filter medium (24). The main filter element (20) is received in a filter housing (30). The main filter element (20) includes at least one retaining element (22) for stabilizing the position of the main filter element (20) in the housing (30).
