Product Features
        In pharmaceutical, electronic, chemical, microbial fermentation, blow moulding, pressure detection and other industrial production, there are many medium-pressure compressed air to be used to 1.6-4.0 MPa in power plants, naval ships, military and national defense facilities. At present, piston air compressors are mostly used at home and abroad, while piston air compressors are characterized by large vibration, high noise, large leakage and short service life, so their efficiency is very low and the same work is done. The medium pressure oil-free screw machine has compact structure, high working efficiency, low noise, low vibration, easy maintenance, low operating cost and good air quality. At the same time, the series of machines are controlled by micro-computer system. The whole machine has multiple protective performance of pressure, temperature and overload energy.
1.Constant pressure control: high-precision constant pressure control with a pressure fluctuation range within0.01MPa.
2. Variable frequency soft start: remove peak current during starting, avoid the power grid impact, prevent the current impact through gradual speed regulation and improve flexibility; 
3.No idling: prevent idling of the compressor during running and reduce invalid energy consumption;
3.High performance vector control: low-frequency starting provides a large torque and a low running current, ensuring to get a reasonable torque to drive the air compressor to run stably with the minimum temperature rise of the motor within a wide speed range;
