OIL-FREE WATER LUBRICATION NORMAL PRESSURE AIR COMPRESSOR

OPPAIR Oil-Free Variable Frequency Screw Compressor:
1.Constant pressure control: high-precision constant pressure control with a pressure fluctuation range within 0.01MPa
2.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
4.The permanent magnet motor adopts a high-efficiency rare earth magnet, without loss of excitation at 180 providing a long service life and saving about 6%~7% more energy than an ordinary variable frequency motor: Obtain the maximum efficiency within a wider range to make the air compressor more energy-efficient
