    Abstract: The powder drying system comprises a powder processing unit (1), and a filter unit (400) defining a central vertical axis (405) and including a filtering chamber (401) accommodating a plurality of bag filters (407), each having a bag filter wall and a top opening, a top portion (402), and an exhaust chamber (403) at or near the top portion (402). The filtering chamber (401) is provided with an inlet (410) configured to allow entry of powder carrying gas to be filtered, and the exhaust chamber (403) has an outlet (420) configured to allow exhaust of filtered gas. In the filtering chamber (401), gas flows through the wall of the bag filters (407), upwards and out through the top opening of the bag filters (407), into the exhaust chamber (403) and further to the outlet (420). the inlet (410) of the filtering chamber (401) is positioned at the top portion (402) of the filter unit (400), and that said inlet (410) includes at least one inlet duct section (415) adjacent the filtering chamber (401) and arranged substantially centrally in the top portion (402) of the filter unit (400).
