G4-73 and Y4-73 boiler pass, induced draft fan is suitable for power plant 2 ~ 670T / h steam boiler pass, induced draft fan systems. In no other special requirements, G4-73 can be used for mine ventilation and general ventilation. Fan transmission medium is air, the maximum temperature should not exceed 80 ℃; medium transport induced draft fan Y9-35 boiler flue gas fan, the maximum temperature should not exceed 250 ℃.
