CLEANING DEVICE FOR VENTILATING DUCT SYSTEMS

摘要

A cleaning device for ventilating duct systems performs mechanically that which has hitherto been performed almost entirely manually. The device comprises a working head, e.g. a brush (7), flow flanges (6), a drive transmission (4 and 9), a suction pipe (5), a motor (1) and a suction fan (2) sucking the dirt taken off in the cleaning from the duct and conveying it into a filter (3).
