Abstract
a presente invenção refere-se a um conjunto de ventilador axial de ponta livre que se caracteriza por um cilindro de proteção compreendendo uma entrada, o raio da referida entrada na sua extremidade a montante sendo maior do que o raio da referida entrada na sua extremidade a jusante. um ângulo, em um plano incluindo o eixo do ventilador, entre a superfície da referida entrada e a direção do eixo do ventilador varia de forma não monotônica em relação a uma coordenada de superfície que aumenta com a distância ao longo da superfície da entrada.
