摘要：
The present invention refers to an impeller (1) for a ventilation unit (10), especially for use in plants for the aerobic treatment of organic waste. According to the invention, said impeller (1) comprises means (9a) adapted to create an under-pressure zone in the central region of the impeller itself, at its hub (5). Thanks to this measure, condensate water deriving from the humidity of the air sucked/blown by the ventilation unit (10) is prevented from leaking along the rotation shaft (24) of the impeller (1), towards its motor and towards the outside environment.
