Abstract

Trata-se de um elemento de filtro que inclui uma construção de meio filtrante pregueado que define um volume interior. A primeira e a segunda tampas de extremidade opostas são presas às extremidades opostas do meio filtrante. Uma estrutura de sustentação sustenta o meio filtrante e é orientada de modo operacional no volume interior. A estrutura de sustentação se estende da primeira face interior oposta até a segunda face interior oposta. A estrutura de sustentação é fornecida para se estender menos do que uma extensão completa entre a primeira tampa de extremidade e a segunda tampa de extremidade.
