6. Unlimited starts and stops, high reliability.
7. Due to the flexibility of the permanent magnet synchronous motor structure of the screw air compressor, the bearings with high failure rate of traditional motors can be omitted, the design of poor coaxiality can be avoided, and the reliability of the transmission system has been improved;
8. Large starting torque, low noise and low temperature rise;
9. The permanent magnet synchronous motor can still maintain good working condition at low frequency;
10. The corresponding volume can be smaller. The power of permanent magnet motors with the same volume and weight can be increased by about 30%; the volume, weight, and materials used of permanent magnet motors with the same power capacity can be reduced by 30%;
11. Combined with Fusheng's high-efficiency body and rigorous system design, it brings users a value-for-money energy-saving experience.
12. The centrifugal fan is used to directly inhale cooler air from outside the unit to cool the cooler, and discharge the hot air directly from the top. The cooler itself also has a large heat exchange area, and the cooling effect is optimal.
13. The centrifugal fan is located in a series of suction holes inside the body and discharges the hot air inside the unit to the top. This unique cooling flow field design keeps the temperature inside the screw air compressor always low while greatly reducing the noise caused by fan action.
14. The electric control box directly inhales cooler air from the outside, which also ensures the heat dissipation effect.
15. When cleaning the cooler, there is no need to disassemble the air guide hood and door panel, just remove the cover.
16. The air inlet of the whole machine and the air inlet of the cooler are equipped with high-efficiency filters to effectively prevent impurities from entering the body or adhering to the cooler to ensure the cooling effect.

A screw air compressor is a type of air compression equipment commonly used in industrial and commercial applications. As a new type of air compressor, it is more convenient to operate than traditional piston air compressors, not only because of its stable performance, but also because of its low vibration frequency and low noise, so there is no need to worry about piston noise. Their main purpose is to compress a large amount of air into a smaller volume and provide high pressure and high flow rate of compressed air.
Â
The purpose of using a screw air compressor is as follows
Â
1. Providing power: Screw air compressors are the power source for many industrial equipment and tools, such as pneumatic tools, spray painting equipment, refrigeration equipment, etc. They compress air to high pressure and then pipe it to equipment that requires compressed air for power.
Â
2. Store energy: An air compressor can store compressed air in an air tank for emergency use. This method of storing energy can cope with peak gas consumption and sudden gas consumption, providing a stable and continuous supply of compressed air.
Â
3. Processing and production: Screw air compressors play a key role in many production processes. They are used in gas separation, pipeline transportation, material transportation and other processes to provide stable compressed gas and play a vital role in many industrial fields.
Â
Screw air compressors can also be integrated with other equipment and systems, such as cooling systems, air conditioning systems, pumping stations, etc., to achieve wider applications and benefits. The most important thing is that the screw air compressor can have continuous trouble-free movement, long service life, and simple maintenance, which can save more maintenance costs.
