SDF tunnel blower

The SDF type counter-rotating axial flow ventilator for tunnel construction is a new generation of energy-saving and low-noise counter-rotating axial flow local ventilator developed and produced by Chongqing Feierda Ventilation Equipment Co., LTD. (adopting the twisted and curved blades of the current domestic and foreign aerodynamic design). This ventilator features a compact structure, low noise, high pressure, large flow, high efficiency, stable operation and easy maintenance. In tunnel excavation construction, energy consumption can be significantly reduced and energy saved. During the tunnel construction process, the use of counter-rotating local ventilators can reduce the number of ventilators used and increase the ventilation distance due to their large flow rate and high air pressure. Their compact structure makes them convenient for transportation, installation and use during construction.

The SDF type counter-rotating axial flow ventilator for tunnel construction can be manufactured into single-speed, dual-speed, triple-speed, variable-frequency stepless speed regulation, explosion-proof and non-explosion-proof types according to user requirements, which is convenient to meet various construction conditions and energy-saving and consumption-reducing requirements of users.

The SDF type counter-rotating axial flow ventilator for tunnel construction can be manufactured as a pressure type or exhaust type ventilator according to the user's requirements.

The SDF type counter-rotating axial flow ventilator for tunnel construction can be designed according to the user's requirements for environmental noise.

Main uses and applicable scope

It is mainly used for ventilation in underground tunnel (roadway) excavation in fields such as highways, railways, power, subways, and mines.
