Abstract

"SISTEMA DE DUTO DE AR PARA O TRANSPORTE E FILTRAGEM DE UM FLUXO DE AR E MéTODO DE PRODUçãO DE UMA PLURALIDADE DE FILTROS CÈNICOS". Um sistema de duto de ar inclui um filtro de tecido cónico disposto em um duto de ar cilíndrico. Em algumas modalidades, ambos o filtro e o duto de ar são infláveis. Um colar de tecido e um par de zíperes não apenas permitem que o filtro seja radialmente removido para limpeza, mas, também, permite que o sistema de duto de ar continue a operar com o filtro removido. Pregas podem prover o filtro com mais área superficial, e as pregas podem ser interconectadas em um padrão alternado, para se impedir o filtro de inflar demasiado.
