摘要： The present invention refers to a ventilation unit (1) arranged to effect flow reversal, according to two opposite directions, of a gas flow generated by a fan without reversing the rotation direction of the fan. The ventilation unit (1) includes a fan (5), at least a first piping arrangement (15) through which a gas flow is intended to pass in one of the two possible directions depending on whether it is blown or sucked by said fan, and a switching assembly (9) arranged between said fan (5) and said first piping arrangement (15), at least a switching device (19, 21) being provided in said switching assembly (9) and being movable between two positions for selectively and alternately connecting said first piping arrangement (15) to the delivery duct (7b) and to the suction duct (7a) of said fan, so as to allow the passage of a gas flow in a direction or in the opposite direction within said first piping arrangement.

摘要： An impeller for a ventilation unit, especially for use in plants for the aerobic treatment of organic waste, is provided. The impeller comprises a housing, a pair of mutually facing plates received within the housing and provided centrall with a through-hole for a cylindrical hub, and a plurality of first radial blades arranged between the plates. The impeller further comprises second radial blades arranged on at least one plate, on its side facing the inner wall of the housing and extending from the cylindrical hub toward the periphery for creating an under-pressure zone in the central region of the impeller itself, at its hub. Thanks to this measure, condensate water deriving from the humidity of the air sucked/blown by the ventilation unit is prevented from leaking along the rotation shaft of the impeller, towards its motor and towards the outside environment.
