1. A blow-by gas filtration assembly fluidically connectable to a crankcase ventilation circuit of an internal combustion engine to receive blow-by gases and filter the blow-by gases from the suspended particles contained therein, wherein the filtration assembly has an axis and comprises:
a main body comprising a filtration chamber extending along said axis and an outlet mouth made at the axis;
a filter group which extends along the axis and has a hollow cylindrical shape comprising a central cavity, housed in said filtration chamber crossable by blow-by gases radially from outside to the inside;
a command group supported on the main body operatively connected to the filter group to command the filter group in rotation about the axis;
a support group supporting the filter group to the main body, comprising:
i) a bearing element comprising an outer fifth wheel with an outer portion sealingly engaging an entire circumference of an outlet edge defining the outlet mouth and an inner fifth wheel defining an outlet passage through which filtered blow-by gases flow; and
ii) a hollow tubular element extending along the axis defining an outlet duct of the filtered blow-by gases, comprising a bearing end operatively connected to the inner fifth wheel and a support portion extending from said bearing end, in the central cavity, wherein the filter assembly is mounted on said support portion and fluidly communicates with the outlet mouth.
