Zusammenfassung:PROBLEM TO BE SOLVED: To provide an air cleaning apparatus which can discharge/remove dust and the like included in the air taken from the outside air while easily and quickly separating the same in air supply/discharge pipes.SOLUTION: In a forced air ventilation system of a cylindrical double pipe structure, the air cleaning apparatus is disposed to discharge and remove the dust and the like separated through a venturi mechanism part communicating an outer pipe and an inner pipe, to the outside air with the indoor air, while separating the dust and the like in the air by centrifugal separation by generating cyclone current in the outside air in the air supply pipe. This air cleaning apparatus can dispense with a filter, a dust collection tank, cleaning liquid and the like used in a conventional cleaner, and can be provided as a maintenance-free air cleaning apparatus.
