Abstract
Ventilateur transversal permettant, malgré son faible encombrement, de souffler un grand débit sous une pression élevée avec une très bonne répartition de l'air dans un refoulement pouvant avoir un grand allongement Les disques sont prolongés au-delà de la périphérie des aubes qui sont frettees par des anneaux dont le diamètre extérieur est, comme celui des disques, au moins égal à 1,09 fois le diamètre à la périphérie des aubes : les crosses comportent des dispositifs pour limiter les retours à l'aspiration. Un tel ventilateur peut être utilisé dans les données où on cherche à souffler par des orifices de grand allongement, tels des séchoirs, etc.
