This series of fans have single stage impeller and double stage impeller two types of structure. Usually, the draught fan and induced draft fan are single-stage impellers. When the primary fan and induced draft fan are desulphurized and sold out, the fan adopts double-stage impellers.

Single stage impeller:
Pressure: 300 ~ 12000 pa
Flow rate: 25~1100 m3/s

Two-stage impeller:
Pressure: 1500 ~ 25000 pa
Flow rate: 15~1175 m3/s

> The fan is normally arranged horizontally, but in special cases, it can also be arranged vertically.
> Fan is generally vertical air inlet and horizontal air outlet, fan inlet box can be rotated according to user needs.
> fan blades adopt hydraulic adjustment during operation, the blade Angle adjusting range from - 30 ° to 30 °, the hydraulic system working pressure is 2.5 ~ 6.3 MPa, adjust the total travel time of 20 ~ 45s.
