7.5~10.5m³/min Two Stage Screw Air Compressor 55KW 7.5~10.5m³/min Air Cooling
Features
1. Two stage screw air compression of with reasonable pressure ratio, such as smaller leakage, lower noise design of host. It combines the level 1 compressed rotor and the secondary compressed rotor within a case, and directly transmit by top gear , makes every level of the rotor at running time to get the best linear velocity of gas production matching, at the same time, reasonable pressure ratio can effectively reduce the compression leakage again, so the compression efficiency is much higher than that of single stage compression. So, compared with the single stage compression, two stage compression more efficient!
2. The oil injection two stage screw air compression under the same power, the pressure volume is more 12% - 18% than the volume of single stage. to compress the same air volume, two-stage compression can save an average of 15% of power than the single stage, Rotor and bearing force is small, and the rotor diameter is big, rotational speed is low, so the operation more reliable.

⊙ Twin-screw air compressor introduced mainframe
Spray
All are screw-type compressor with a modem environmental-protection paint. Its surface machining so many years after the use of castings can effectively avoid corrosion.
Shell
The modem word processing centers under the control of the technical specifications for testing. ’The most advanced machinery and the use of modem technology and constant monitoring. It applied to all processing operations. For us on the Company’s compressor quality certification of the commitments made by providing good protection.
Shaft sealing device
Equipped with dual wheels metal framework amine fluoride rubber ring to withstand certain pressures. Formation of the shaft seal can be lubricating device. Bush axis of the company’s exclusive use my special processing technology. A perfect sealing performance and long life.
Rotor
Each screw compressor is the heart of the compressor mainframe. From the latest CNC machine operators of multi-level screw fully automated manufacturing process and materials used by the higher minimum guarantee its tolerance. Reliability stronger. Ground processing and computer control of the multi-step rotor combine. 100% of the rotor to ensure the accuracy of profile.
Bearing
To ensure the speed and load bearing capacity. Using screw compressor bearing capacity of a very high-quality bearings. Guaranteed longer bearing life.
⊙ why choose us
Longer service life of the master machine
The rotor uses asymmetrical line running at a low speed with the support of the ball bearings and roller bearings as a result. The damage and the cost are lowered and the service life is extended. Some force is counteracted by the axial force generated by the bevel gear. So the load on the bearings of the master machine is lowered.
Permanent alignment of the electromotor and the master machine
Different from the strap compressor, the SRC series compressor can integrate the electromotor with flange, shaft coupling box-gear box. and the master machine into one in such way the master machine and the electrometer are aligned forever in the transpiration. The SRC series compressors equipped with effective and fully sealed air-cooling electromotor.
