Abstract

La présente invention concerne un système de hotte ayant un rotor intégré, capable de décharger du gaz contaminé produit par une source de contamination en temps opportun de manière à empêcher la contamination de l'air intérieur à l'avance. Le système de hotte ayant un rotor intégré comprend un boîtier, un ventilateur d'évacuation, ledit rotor et une unité de décharge. Le boîtier est agencé au-dessus de la source de contamination, et le côté inférieur de celui-ci a un orifice d'entrée pour l'alimentation en gaz contaminé. Le ventilateur d'échappement est agencé à l'intérieur du boîtier, et tourne au moyen d'un dispositif d'entraînement en rotation de façon à forcer l'évacuation du gaz contaminé. Le rotor tourne conjointement avec le ventilateur d'échappement pour empêcher la diffusion du gaz contaminé dans une zone intérieure. L'unité de décharge est agencée sur une surface supérieure du boîtier de façon à décharger le gaz contaminé aspiré par le ventilateur d'évacuation à l'extérieur.
