Abstract (en)

[origin: WO2016097639A1] The invention concerns a lateral aerator (2) for a ventilation duct (1), comprising blowing openings (5, 5') each formed by a slot (3, 3') and a fin (4, 4') having a guiding face (4a, 4'a). According to the invention: a central axis (DTH) of each guiding face (4a, 4'a) is inclined in an upstream direction, the central axis (DTH) of the guiding face (4a, 4'a) of each of the first and last fins (4, 4') is inclined at an angle of between 10° and 35° and between 60° and 85°, the angle of inclination of the central axes (DTH) of the guiding faces (4a, 4'a) of the second fin to the penultimate fin (4; 14) increases gradually, and the width of the guiding face (4a, 4'a) of each of the second to the last fins (4'; 14') is greater than or equal to that of the fin (4; 14) immediately upstream.
