一、Introduction and main use
SDF (i.e. tunnel construction special axial flow ventilator) is mainly used for the construction ventilation of high-speed railway, highway, railway tunnel, water diversion tunnel, underground and petroleum pipeline project and other underground projects. It is used for press-in air supply through the wind belt, and the temperature of the conveyed gas should be ≤80℃, without strong corrosiveness, and the dust content should be ≤200mg/m³.135 It is suitable for the altitude of ≤1500m above sea level, and the working temperature is -20℃~+40℃.
二、Second, the core features
1. Counter-rotating double-stage design
The two-stage impellers are driven by two motors of the same power and rotate in the opposite direction. After the first-stage impeller accelerates the airflow, the second-stage impeller, which also functions as a static lobe, further boosts the pressure and increases the efficiency by 15% to 20% compared with the single-stage fan. It supports expansion to three-stage, four-stage or five-stage counter-rotation to meet the high wind pressure demand of ultra-long tunnels.
2. Modularity and graded use
can flexibly choose the whole machine or single-stage operation according to the length of tunnel boring (e.g., start only the first-stage fan), reducing energy consumption by more than 30%.
3. Low-noise technology
The inlet and outlet are equipped with double-layer mufflers filled with high-efficiency sound-absorbing materials (such as
perforated plate + sound-absorbing cotton), and the noise is controlled at 74~94dB(A), which is better than that of the
conventional axial fan.
4. Intelligent speed control and energy saving
Frequency control: standard with frequency conversion system, to achieve stepless speed regulation, to adapt to different working conditions of air volume requirements.
5. Three-speed adjustment: the new SDF(C) series supports three speeds: high/medium/low. For example, SDF(C)-No10 has a high speed air volume of 770~1500m³/min, and the low speed only requires 6×2kW power, which saves energy significantly.

三、 structural components
SDF fan adopts modular design, the main components include:
1. Collector: optimise the intake airflow and reduce turbulence loss.
2.Impeller and motor
2.1 Impeller: wing-type streamline blade, made of aluminium alloy or high-strength steel, directly connected to the motor shaft,with small clearance and high efficiency.
2.2 Motor: explosion-proof design, voltage support 380V/660V/1140V, built-in cooling duct.
3. 3. Muffler: double-layer cylinder structure (perforated inner plate + sound-absorbing layer + steel shell), removable and
replaceable sound-absorbing materials.
4. 4. Host shell: Q235 steel plate welding, flange connection, support plate reinforcement to ensure transport stability.

四、 technical advantages
1. High-efficiency wind pressure and air volume
Wind pressure range of 275~9880Pa, air volume up to 60,000m³/h (e.g., SDF-11.2 type), far more than ordinary axial fans, air supply distance up to 2~3km.Full-pressure efficiency of ≥ 85%, energy saving of more than 30% than traditional fans.
2. Adaptable scene coverage
Plateau environment: Adapt to low air pressure working conditions through multi-stage speed regulation.Small section tunnels: compact structure (e.g. No4.0 machine number 400mm in diameter) is suitable for narrow spaces.
3. Convenient and economical maintenance
supports non-stop oiling and lubrication of bearings, and the muffling cotton can be replaced to prolong the life.Adjustable blade angle to suit airflow requirements without changing hardware7.

五、Typical application scenarios and selection
1. Short tunnels/small sections: SDF-2-No4.0~No5.6 (power 2×2.2~2×11kW) is preferred,such as underground ducts.
2. Long distance tunnel: Prefer multi-stage model (e.g. SDF-6-No18) or inverter model for relay air supply.
3. Energy-saving scenarios: three-speed models (e.g. SDF(C) series) reduce no-load loss by speed reduction, suitable for staged ventilation needs.
