The present invention relates to a hood (40) of a multi cyclone block (12) and an air cleaner (10). The cyclone block (12) has a plurality of cyclone cells (28). The hood (40) having at least one hood-inlet (50) and at least one hood-outlet (52) for air to be fed to the cyclone cells (28). The at least one hood-outlet (52) is designed for surrounding, a plurality of cell-inlets (36) of the cyclone cells (28) of the cyclone block (12). A wall (70) of the hood (40) defines a distributor volume (72) inside the hood (40), which is located between the at least one hood-inlet (50) and the at least one hood-outlet (52).
