Abstract

"FILTRO DE CASSETE". A invenção refere-se a um filtro de cassete, abrangendo uma moldura e um material de filtro plissado inserido na mesma, bem como uma grade protetora com aberturas de passagem, a qual está fixada na moldura a uma distância do material de filtro e apresenta uma resistência à corrente, que é menor do que aquela do material de filtro plissado. A invenção é caracterizada pelo fato de que a grade protetora (1) consiste em ao menos uma tira de folha (2) curvada em torno das aberturas de passagem (3), a qual se estende paralelamente à direção de afluxo (4) do meio a ser filtrado, e toca retroativamente em pontos de contato (6), fora das aberturas de saída (3) ao menos uma outra tira de folha (5) identicamente curvada, e está colada com a mesma nos pontos de contato (6).
