Abstract

The invention relates to a gas intake zone of a separable gas filter housing which removably accommodates a filter element. The gas intake zone is used as a prefilter and comprises a plurality of axially adjacent, axially impinged cyclone collectors that are provided with respective spin generators in the inlet zones thereof and gas-discharging immersion tubes at the discharge end within annular ducts which are located between the immersion tubes and the respectively associated outer cyclone walls while being used for pre-separating dirt particles separated in an outer radial direction in the individual cyclones by means of centrifugal forces, the immersion tubes being axially dipped into the interior of the cyclone collectors.
