Abstract
"DISPOSITIVO DE VENTILAçãO CENTRIFUGA, VENTILADOR INDUSTRIAL, E, PROCESSO DE VENTILAçãO CENTRìFUGA DE UM FLUIDO". A invenção se refere um dispositivo de ventilação centrífuga (1) que possui pelo menos uma saída de recalque (20) e pelo menos duas entradas de fluido (2, 3) dispostas de um lado e do outro de uma roda de ventilação (4)suscetível de ser acionada em rotação por um meio de acionamento, cada entrada (2, 3) sendo associada a um sistema de regulação (30) do fluxo de aspiração do fluido capaz de criar uma vazão de aspiração dissimétrica entre as entradas caracterizado pelo fato de que as entradas (2, 3) são equipadas com sistemas de regulação
