The Sailiou series permanent magnet variable frequency high-pressure axial flow fan is a large air volume, high air pressure, high efficiency, energy saving and power saving, ultra-quiet axial flow fan. It is suitable for temporary ventilation projects in tunnel construction with long construction distances, great construction difficulties, and high energy consumption and noise requirements.

1. The fan adopts European fluid technology, and the fan flow channel is synchronized with the most advanced theoretical model of aircraft engine flow channel.

Through simulation analysis, the relationship between air volume, air pressure and efficiency is optimally matched, with the highest

2. The fan adopts composite impeller, which is light in weight and high in strength; G2.5 grade ultra-high dynamic balance, stable operation, small vibration and long service life of the fan

3. The fan blades can be adjusted in angle to meet different tunnel construction ventilation requirements. The blade installation angle error is small (≤±1"), and the flow field is stable and efficient.

4. The fan adopts a three-level design of sound insulation, silencing and noise reduction to achieve a super quiet effect, with noise ≤80 decibels.

5. The fan uses a high-efficiency permanent magnet variable frequency motor with a strong magnet inside. It does not require winding coil excitation, which greatly improves the motor efficiency and saves more than 10% energy compared to traditional motors. The bearings use international first-line brand bearings such as SKF/NSK/FAG, making the motor more durable.

6. The fan control cabinet adopts synchronous frequency conversion control system, 0~100HZ stepless adjustment, and is equipped with a 7-inch LCD screen to display the operating status in real time. At the same time, the control cabinet can use local control mode and mobile phone APP remote control mode to adjust the air volume and view the operating frequency and power function of the fan.

7. The fan control cabinet can withstand voltage fluctuations of no more than 15%, and has anti-turbulence protection, dual lightning surge protection, and overvoltage, overcurrent, overload, short circuit, phase loss, phase error, high temperature and other protection functions; at the same time, it can track and manage the status of the fan operation in real time, and perform online fault diagnosis and early warning.

8. The fan is equipped with an automatic lubrication and maintenance-free system, which is simple and easy to operate.
