Abstract

Le problème décrit par la présente invention est de fournir un épurateur d'air ayant une capacité de collecte de poussière suffisante et une capacité de désodorisation suffisante, et pouvant éliminer un bruit. La solution selon l'invention porte sur un épurateur d'air (1) qui comprend une unité de collecte de poussière (22), une unité de désodorisation (23) et une soufflante (25). L'unité de collecte de poussière (22) comprend deux collecteurs de poussière électriques ayant une faible résistance à l'air. Dans l'unité de désodorisation (23), deux plaques de radiateur (23c) recouvrent uniquement une partie d'un filtre de désodorisation (23a). Pour cette raison, l'unité de désodorisation (23) a une faible résistance à l'air. Par conséquent, même si la soufflante (25) a un turboréacteur à double flux relativement silencieux (25a), un débit d'air suffisant peut être assuré et, de ce fait, une capacité de collecte de poussière suffisante et une capacité de désodorisation suffisante peuvent être obtenues.
