Abstract

pré-purificador de ar para filtro a jusante do mesmo e método para regular o respectivo desempenho. um sistema de pré-purificador de ar de separação inercial inclui uma inserção substituível montada de maneira removível no pré-purificador e alterando a velocidade do fluxo de ar através do pré-purificador mudando a área de fluxo do trajeto de escoamento através do invólucro de pré-purificador. a inserção substituível é substituível com uma inserção diferente para o mesmo invólucro de pré-purificador, cuja inserção diferente proporciona uma área de fluxo diferente através do invólucro de pré-purificador, permitindo uma eficiência de pré-purificador selecionável vs. trade-off de restrição comforme escolhido pelo usuário para uma aplicação particular, permitindo regulagem de desempenho de pré-purificador pelo usuário.
