L'appareil de filtration d'air décrit ici comporte une
chambre où sont situés un ou plusieurs filtres contenant du
charbon activé, et permettant de faire entrer de l'air vicié
et d'en faire sortir l'air filtré. Cet appareil comporte
aussi un système intégré pouvant effectuer le lavage de la
matière active du charbon activé des filtres, par des jets
d'eau chaude. Le système de lavage à l'eau chaude permet la
désorbtion des Produits Organiques Volatils (POV) captés par
les filtres au charbon activé sous forme de liquide plus ou
moins huileux, pouvant être récupéré ou non selon un système
plus ou moins complexe de récupération des liquides. Les
filtres après avoir été lavés par l'action du système de
lavage à l'eau chaude, peuvent être réutilisés tels quels.
Le système intégré de lavage s'opérera lorsque l'entrée et la
sortie de l'air seront cessés.
