The combined screw air compressor integrates the parts including screw compressor, freeze drier, fine filter and air tank, making it convenient for the user to install, use and move. After the air pass the integrated system, the quality of the air is made largely better to satisfy process requirements of various companies. It is of beautiful appearance, stable performance and economy. It is one of the important series exported by our company.


Advantage:
Air End
No vibration and low noise interpret perfectly the genuine made in Germany. Big rotor, low speed of rotation and direct connection.
Motor
First-class motors are adopted, with the level of protection being IP54 and insulation level being F.
Rotor
Rotors are asymmetric in profile, backed up by ball bearings and roller bearings. Operates at a low speed, thereby low in abrasion and maintenance expenses, air end is long service life. Helical gears can produce axial force to kill some acting force, which reduces the load of the bearing of air end.
Control panel
Intelligent microcomputer-based control technology can monitor and control in all aspects the complete machine following your instructions, remote control realizes unattended operation, and the user-friendly human-machine interface displays instructions and parameters in written form also, it can function to self diagnose faults, give warning and automatically regulate the capacity.

Motor Efficiency Class: Ultraefficient/IE3/IE2 as per your required Motor Protection Class: IP23/IP54/IP55 or as per your required Certification: CE/ISO9001/TUV/UL/SGS/ASME Voltage: 380V/3PH/50HZ/60HZ, 220V/3PH/50HZ/60HZ, 400V/3PH/50HZ/60HZ, 440V/3PH/50HZ/60HZ, 415V/3PH/50HZ/60HZ, 230V/3PH/50HZ/60HZ, dual voltage is also ok |
Highly-quality shaft coupling elastic body can buffer and compensate for the imbalanced moment of operation. The elastomer is designed into and involute cambered surface, which effectively avoids stress concentration and improve the buffering effect of the elastomer to increase its bearing capacity. In addition, the high-quality materials ensure excellent durability for the elastomer and can better absorb the vibration arising from the rotation to remove noise. Since no wearing parts are used for the double-screw compressor air end, it can operate for up to 40000-80000 hours between failure if well maintained.


Features:
- 1. A precisely-made central bracket is used to keep the motor aligned permanently with the air end.
- 2. A highly resilient coupling is adopted to make the compressor operate smoothly, and the elastomer is long in useful life.
- 3. The discharge pipe is double-wall corrugated pipe, and the oil way uses a special high-pressure hose which is resistant to temperature up to 125℃.
- 4. For the extremely high temperature conditions in some districts, the large-area plate heat. exchange and high-efficiency water chiller are used.

Advantage:
1.Large displacement: Displacement 10% higher than ordinary piston compressor.
2. Energy-saving: Compared with piston air compressor, this series of models for the new national standard two energy efficiency products, excellent energy saving.
3. Easy to operate: 24 hours unattended all day work, free load automatically start, full load automatically shut down.
4. Strong stability: Under long time working, displacement and pressure stable, no crash phenomenon, low failure rate.
