Abstract

La présente invention a pour objet un épurateur d'air à deux étages. Elles est caractérisée en ce que cet épurateur comprend un carter cylindrique dans lequel est logé un dispositif de filtrage comportant un filtre principal en papier poreux plissé et un filtre de sécurité en matière poreuse, l'épurateur étant agencé de façon à empêcher l'air entrant de parvenir à la sortie sans traverser les filtres, à permettre un enlèvement automatique par raclage des particules de matière accumulées sur la surface intérieure de l'épurateur à chaque fois que le filtre principal est changé et à faciliter la mise en place et l'enlèvement du filtre de sécurité sans intervention d'outils. Elle se rapporte à des installations d'épuration d'air.
