Abstract

respiradores com peça facial filtrante resistentes a respingos de fluidos a presente invenção refere-se a um respirador com peça facial filtrante 10 que compreende um corpo de máscara 12 e um arnês 14 que é unido ao corpo da máscara 12. o corpo da máscara 12 inclui uma camada de filtro 30 e uma manta de revestimento fibrosa de não tecido 16. a manta de revestimento fibrosa 16 é parcialmente fechada e é genericamente paralela a e espaçada em relação à camada de filtro 30 de modo que o ar que passa através da manta de revestimento 16 possa se mover livremente entre a manta de revestimento 16 e a camada de filtro 30 para poder entrar na camada de filtro 30 em essencialmente qualquer ponto disponível sobre a superfície da camada de filtro 32. o respirador da invenção é benéfico no sentido de que pode proporcionar uma proteção muito boa contra respingos de fluidos e contaminantes transportados pelo ar, e ao mesmo tempo apresenta uma queda de pressão extraordinariamente baixa no corpo da máscara durante a respiração.
