SDF Tunnel Fan
SDF（P）tunnel construction dedicated frequency conversion energy-saving fan is a new type of tunnel
construction fan developed by the company’s R&D team in response to market demand and the company’s
product features, adopting advanced design concepts and improving performance data. Applicable to all
kinds of tunnel construction, compared with traditional fans can save more than 30% of electricity.
This series of fans has a wide range of applications. It can be freely adjusted according to the amount of
wind and air pressure required for tunnel construction, and it can increase or decrease the number of motors
according to the length of the tunnel to meet the requirements for different lengths of tunnel construction.
Key Features
- （1）This series of fans uses variable frequency controlcabinets, which can greatly reduce the impact on the grid and the requirements for the power supply capacity, reduce the input power and increase the power factor.（2）According to the requirements of air volume and air pressure at different stages of tunnel excavation, suitable air volume and air pressure are supplied by adjusting thefrequency of the motor to realize stepless speed regulation and thus save electricity.（3）According to the construction environment, the different requirements of the air volume and the air pressure are adjusted so that a kind of power fan can operateunder different powers, realizing multi-purpose use of one machine, thereby effectively saving power and investment.
