Oil free screw air compresor-30kw-variable frequency air compressor The most advanced oil free air end over the world---full stainless steel design. Inheriting the full stainless oil free air end of B. Zimmern technology ---France. 100% oil free air, 100% purified air, 100% oil free compressing system. Water is used for sealing, cooling and lubricating. Thus, the efficiency has been greatly improved. The operation temperature of the air end is not higher than 50 ºC, lifespan is over 25 years. Advantages for using the variable frequency screw air compressor. Δ Energy-saving, automatically control the speed, avoid the frequent loading and unloading. Δ Precise exhaust pressure, the pressure fluctuation range can reach 0.01Mpa. Δ Avoid the peak value of the current, have no effect on the power grid. Δ Switch between power frequency and variable frequency, guarantee the minimum electricity expenses according to the air consumption. √ Energy saving, Environment protection, Reliability
