Abstract
resumo dispositivo de filtração de ar com sistema de distribuição de ar ajustado a presente descrição apresenta um dispositivo de filtração 10 que inclui um alojamento 12 que tem uma pluralidade de subseções 32, 34 e 36, sendo que cada subseção é adaptada para receber um elemento de filtro 26, 28 e 30. uma entrada 18 é disposta em um primeiro local no alojamento 12 e um sistema de distribuição de ar a montante é colocado em comunicação fluida com a entrada 18 e com cada uma das subseções 32, 34 e 36. um sistema de distribuição de ar a jusante está em comunicação fluida com cada subseção 32, 34 e 36, e uma saída 20 em comunicação fluida com o sistema de distribuição de ar a jusante. os sistemas de distribuição de ar a montante e a jusante são construídos para manter a mesma velocidade de fluxo de ar através de cada subseção. com o uso de tal construção, a vida útil total do produto pode ser prolongada, minimizando-se ao mesmo tempo a resistência à pressão do filtro total. 1 / 1
