Abstract

"SUPORTE DE FILTRO, CONJUNTO DE FILTRO, E, RESPIRADOR DE PURIFICAçãO DE AR ENERGIZADO". Um suporte de filtro (10) que inclui duas ou mais primeiras nervuras de suporte (20a, 20b, 20c) em um primeiro lado do suporte de filtro. As primeiras nervuras de suporte são geralmente alinhadas ao longo de um eixo longitudinal (11). O suporte de filtro também inclui duas ou mais segundas nervuras de suporte (30a, 30b, 30c, 30d) em um segundo lado do suporte de filtro, onde o segundo lado do suporte de filtro é oposto ao primeiro lado. As segundas nervuras de suporte também são geralmente alinhadas ao longo do primeiro eixo longitudinal. Pelo menos uma das primeiras nervuras de suporte é lateralmente desviada de cada uma das segundas nervuras de suporte ao longo de um eixo transversal (13) que é geralmente perpendicular ao eixo longitudinal. O suporte de filtro fornece suporte para os lados opostos de um saco de filtro (40) ou elementos de filtro individuais opostos. Também descrito encontram-se um conjunto de filtro incluindo um filtro e um suporte de filtro, juntamente com um respirador de purificação de ar energizado e montado em capacete no qual o conjunto de filtro é localizado dentro da coroa do capacete.
