Abstract

"DISPOSIçãO E MéTODO PARA FILTRO DE AR DE FLUXOREVERSO". Uma disposição de filtro de ar de fluxo reverso éprovida. A disposição inclui um elemento de filtro (225) que temprimeira e segunda tampas extremas (224), a segunda tampaextrema tendo uma abertura central de drenagem (218). Uma formade funil em uma superfície interior da segunda tampa extrema éusada para direcionar um fluxo de água higroscópica para aabertura de drenagem. A disposição inclui um alojador no qual oelemento de filtro é operacionalmente posicionado durante o uso.Certas características do alojador (401) facilitam a retirada da águahigroscópica do elemento de filtro ao mesmo tempo inibindointerferência com a selagem entre o elemento de filtro e o alojador.
