SDF (C) Special axial flow fan for two-stage and two-speed tunnel construction

1.Characteristics of fan

SDF (C1) double pole double speed series fan adopts double speed adjustable motor, users can choose different speed according to different needs, by changing the speed of the first and second stage motor to achieve energy saving effect.

Due to the use of noise reduction measures, the fan has low noise and less energy consumption, which is especially suitable for the construction of super long and super large tunnels.
