Abstract

The present invention relates to a filter device comprising a filter cabinet (2), at least one filter chamber (3) provided in the filter cabinet (2) and filter elements (11) provided in the filter chamber (3), wherein a pre-separator (31) is provided to separate coarse particles (32) from the air stream (17) loaded or mixed up with particles before said air stream (17) is fed to filter elements (11) in a filter chamber (3). The pre-separator (31) includes at least one nozzle (39) provided in the filter cabinet (2) and divided into several smaller nozzles (43) and said smaller nozzles (43) extend in parallel with each other.
