Two-stage compressed oil-injected screw air compressor possesses the air end with a reasonable pressure ratio, ultra-small leakage, ultra-low noise. It combines the primary compression rotor and the secondary compression rotor in a housing and is driven directly by the front gear so that each stage of the rotor can achieve the optimum line speed, matching to the free air delivery during the operation. Meanwhile the reasonable pressure ratio can effectively reduce the compressor leakage, therefore, the compression efficiency is much higher than the single-stage compression. So, compared to single-stage compression, two-stage compression is more energy-efficient.
Two-stage compressed oil-injected screw air compressor, at the same power, comparing to the single-stage compressed oil-injected screw air compressor is with more than 12% ~18% of free air delivery. In other words, for the same free air delivery, two-stage compressor can save 15% of the power than the single-stage compressor. The bearing capacity of the rotor and bearing is small, with big rotor diameter, low speed, so the operation speed is more reliable.

V. Company Advantages
1.Enormous potentiality, long history
ZheJiang Honest Compressor Co., Ltd. is one British wholly-owned enterprise. Currently in China, OSG has set up three major manufacturing bases (ZheJiang Honest Compressor Co., Ltd, ZHangZhoug Ulite Tools Co.,Ltd., Guang EPT OSG welding), five Manufacturers. Meanwhile we cooperate with the European world- EPT air end manufacturer. OSG ZheJiang possesses a complete production, sales and after-sales service system. OSG has 40 offices and more than 80 after-sales service centers, and products are sold to more than 20 countries.
2. Advanced configuration, world-renowned components, abundant production experience.
The control system is the most advanced. The controller is designed and manufactured by Schneider, France. It is equipped with the large Chinese-English liquid crystal display screen. It can monitor more than 20 main operating parameters, and has the functions of fault recording, maintenance and alarm shutdown. It can achieve efficient intelligent control, unattended.
Remote control: the computer processor can directly check the user’s real-time operating system. Combine the reliability, energy saving, practicality in one. remote control can start, stop, load, unload the compressor and also other local control can be carried out. The operation, alarm and fault and relative local information can be monitored. (detailed description followed)
Remote control function:
Multiple compressors remote centralized control: reduce system pressure, reduce energy consumption, real-time monitoring.
Dual pressure setting: Two system pressure bands can be set manually or automatically to optimize energy use and reduce operating costs.
Delayed secondary shutdown: This function controls the motor to run only when needed, allowing the motor to run less and minimize the energy consumption.
