Abstract
"ELEMENTO FILTRANTE DE MúLTIPLAS CAMADAS", sendo prevista uma camada filtrante principal (1), composta preferivelmente de um não-tecido meltblown, sendo esta responsável pela filtragem absoluta. Uma camada de papel (2) no lado para fluido filtrado serve para apoiar o elemento filtrante, não contribuindo para a filtragem do fluido a ser filtrado. Por essa razão, essa camada pode ser constituída de poros grossos, obtendo-se assim uma resistência pequena ao fluxo. Uma camada (3) no lado para fluido filtrado feita preferivelmente de papel, pode assumir as tarefas de uma pré-filtragem do fluido, bem como a função de proteção e de apoio à camada filtrante principal. Através da estrutura descrita de um material filtrante de múltiplas camadas podem ser fabricados de forma económica elementos filtrantes, principalmente cartuchos filtrantes com pregas em forma de estrela, já que é possível dispensar o uso de camadas de apoio em forma de tela metálica. Isso produz também uma disponibilidade térmica melhor do cartucho filtrante aqui proposto.
