Abstract

"Pá PARA VENTILADOR AXIAL DE BAIXO RUìDO E ALTA EFICIêNCIA". A presente patente de invenção descreve uma pá para ventilador axial que apresenta inovação em sua forma construtiva que resulta numa menor emissão de ruído e numa eficiência mais alta. A pá para ventilador axial, objeto da presente patente, produz uma menor emissão de vórtices do que as pás disponíveis no estado da técnica anterior. Esta menor emissão de vórtices é responsável por um menor nível de flutuações de pressão, o que resulta numa menor emissão de ruído, e é responsável também por um menor gasto de energia na formação de vórtices, o que resulta num aumento de eficiência. A presente pá de ventilador axial pode ser utilizada nas mais variadas aplicações onde é necessária a movimentação de um gás qualquer.
