The compressed air 8 injected from the backwash nozzle 7 is injected into the bag filter 2 through the internal passage 10 of the suction port member 9. When the compressed air 8 passes through the internal passage 10 of the suction port member 9, an ejector effect occurs and an arrow C
As shown by (2), the surrounding air is sucked from the inlet side of the suction port member 9 and injected into the bag filter 2 together with the compressed air 8 and used for backwashing.
