1. Similar to screw compressors, screw fans combine male and female rotors, the male and female rotors rotate and reduce the available volume between them, resulting in air compression
2. Often, they can operate more economically with a wider range of requirements. Depending on the model and provider, they can achieve working pressures of 0.3 to 1.5 bar.
3. The screw blower can adopt VSD (variable speed drive), which can further save energy. The screw blower is based on the principle of adiabatic compression, with a total efficiency of more than 75%, which is more than 20-35% energy efficient than that of the Roots blower. The optimized profile design makes it more efficient.
4. 

1. Air intake filter, the optimally designed air intake muffler not only minimizes the noise of the blower
2. The special high-efficiency motor for screw blower is specially designed by the motor factory according to the performance curve of the blower, which can further improve the efficiency of the whole machine, reduce the specific power, and at the same time allow the motor to run for a long time in a high temperature environment of 55 °C, and the motor protection grade is IP54
3. Color touch screen, graphic display, friendly interface, easy to operate.
4. The advanced start-up device reduces mechanical impact, reduces the requirements for the power grid, and improves the life of the blower. ​​
5. A one-way valve is installed between the expansion joint and the muffler to avoid backflow of compressed air. This design allows the machine to be connected to the grid at any time.
