Abstract: An air filter unit for removing contaminations from air is disclosed. The air filter unit includes an airflow generating device configured to generate and direct at least one airflow from an air inlet to an air outlet, a filter disposed between the air inlet and the air outlet and including at least one filter layer for removing contaminations from the at least one airflow, a heater disposed upstream of the filter and configured to heat the at least one airflow directed towards the filter, an ejection device disposed upstream of the filter and configured to inject a sterilizing agent into the at least one airflow directed towards the filter, and a duct interposed between the air inlet and the filter and configured to feed the at least one airflow to the filter. The duct includes a volute-like outlet portion, and the ejection device is arranged in the duct.

Abstract: A manifold for a filling unit for filling a plurality of articles with a pourable product is disclosed. The manifold includes a first flange configured to be fixed to a tube for filling a tank with a pourable product; a second flange configured to rotate about an axis with respect to the first flange and be fixed to the tank, the second flange defining a passage for a first fluid other than the pourable product and adapted to be conveyed inside the tank; a fluidic line bounded between the first flange and the second flange and configured to be filled with a second fluid in order to prevent contaminant agents from reaching the passage; a sealing element interposed between the first flange and second flange; at least one piston movable along the axis and operatively connected to the sealing element; and a pneumatic circuit operable to exert a pressure on a third fluid acting on the piston, so as to press the piston against the sealing element along the axis.
