Abstract

Dispositif de filtration d'air pollué Ce dispositif est constitué par superposition d'un ensemble de couches tricotées de fil métallique, d'un filtre médian d'arrêt des grains de dimensions notables, constitué éventuellement par un matériau genre laine de roche de faible prix de revient, et d'un filtre absolu en papier plissé de faible perte de charge. Application en particulier à la filtration des fumées de soudure.
