Direct Driven Air Compressor Introduction
According to the characteristics of the domestic environment and the needs of users to use advanced technology and processing equipment based on the huge domestic market.
1, Gear match and seal innovation - optimize the bottom screw rotor precision gear match and sealed, completely solve the process rotor gear disclosure fuel-air mixture and provide a gas volumetric efficiency reduces the cavity compressed air noise when fuel-air mixture passed from the high-pressure chamber to the low pressure generated the cavity compressed air noise.
2, the axis distance innovation - increasing the effective cross-sectional area of the rotor and the active and passive axis distance let the rotor area to reach the highest utilization factor and leave sufficient room for install larger diameter bearings and fundamental solve the failure factors of screw rod bearing wear air compressor after run a number of years.
3, Wisdom leading technology, rather than led by technology - the essence of technology is not the crowd seeking imitate, but rather follow itself., with several high-tech fusion of thinking (optimization) improved to achieve energy saving, environmental protection these two new breakthroughs results, and official leading the new generation of full sail air compressor since 5:6 gear asymmetric line rotor launch.

Description:
Fully seal & double screw,dual shockproof,smooth operation,can be installed anywhere.
With a exquistie shape and compact structure and cover a small area.
Large displacement,stable pressure and high efficiency.
Low exhause temperature (only 7 °C~10°C higher than the ambient temperature)
Safe,liable,smooth operation,little noise and long maintenance cycle and using life.
The intelligent control system completely satisfy the continuous cooperation without man work.
Many screw air compressors operate together and start or shut down automatically
according to the air amount,and no man-work is needed.
It is more energy saving for a single compressor can adjust air demand automatically according to the users' air amount(frequency conversion type).
The degree of tightness of the belt can be auto-matched with the flexible belt. Through adjusting the tensility, the loss of the pressure and efficiency can be reduced to the lowest point and increase the efficiency.
