A pneumatic material conveying system, particularly a waste conveying system, which conveying system comprises at least one feed point (61, 66) of material, particularly of waste material, a material conveying pipe (100, 101, 102) which is connectable to the feed point (61, 66), a separator device (20) in which the material being conveyed is separated from conveying air, and means (3, 4) for providing a pressure difference in the conveying pipe (100, 101, 102) at least during the conveyance of the material. At least a part of the conveying pipe (100) and conveying air channels (105, 106) is formed as at least one circuit in which the suction side of at least one vacuum generator (3) is connected, and the system comprises at least one blower device (4) the suction side of which is connected to the air channel (105, 106) coming from the separator device (20) of the circuit and the blowing side to the conveying pipe (100) or a section of the circuit in connection with the conveying pipe so that it is possible to circulate air with the blower device (4) in said circuit.
