SYSTÈME DE FILTRATION DES POLLUANTS ATMOSPHÉRIQUES POUR UNE CABINE

摘要

An air contaminant filtration system (10) for a cabin (12) includes an external air drawing system (14) for drawing air from an atmosphere surrounding the cabin (12). The system also includes an internal air extraction system (16) for drawing air from an atmosphere within the cabin (120, a main filtration system (18), and a filtered air delivery system (20). In the system, air drawn from the external drawing system (14) and from the internal air extraction system (16) is directed towards the main filtration system (18) for filtration and the filtered air is then directed towards the filtered air delivery system (20) for delivery to the cabin (12).
