An air filtering system for large installations such as spinning machine rooms, textile factories, etc., has a rotating drum with permeable walls through which air is aspirated to the interior of the drum while the accumulated contaminants are removed during the rotation of the drum by a reciprocating vacuum cleaner. In order to protect the bearings of the drum and the drive mechanism from contact with uncleaned air, the drum is carried by rollers which contact only the interior surface of the drum. The drive motor and transmission are also placed inside the drum.
