Mr.Kerry Robinson from Australiatoday I ran the compressor and I am very happy with the workmanship and the quality , it is connected to a nitrogen generator that requires around 0.8 MPA feed air from the 30 kw compressor we are commissioning it I have found that it loads and unloads from 25.5 kw - 30 kw this will be a huge saving on power consumption. -
Pedro Antonio from USAWe've been used Shanghai Rotorcomp compressors over 18 sets from 10hp to 160HP installed with Oxygen generator since 2008. Most of compressors still in good working conditions without much maintenance.

Product Description
75HP air compressor original german air end in TUV certificates, 5 years warranty
Advantages of LGFD High-end Series Screw Compressor:
1. World-leading Made in Germany Rotorcomp screw air end
2. 5 years warranty
3. Extraordinary cooling system design
4. Intelligent control system
5. higher efficient energy-saving motor in IP55 IE3 CE&MEPS, SF1.2

Advantages of our new air screw compressor technology
Ultimate efficiency and reduced noise through
High volumetric output due to
• Reduced internal leakage
• Thermally optimized oil injection system
• Improved suction port efficiency giving reduced
internal losses
Low power consumption due to
• Optimized torque characteristics and reduced
internal friction
• Improved outlet port with lower pressure losses
Reduced noise and low vibration due to
• Smooth rolling of the rotors with new
ROLLING PROFILE®
• Optimized outlet port
Our new EVO® oil-injected screw air ends are among the most efficient air ends in the world
market today.
All of our 30+ years experience in the supply of our well-known B air ends and
NK compact units is built into our new EVO® generation ensuring a highly reliable product.
Using EVO® as the heart, our OEM partners can build compressor systems with ultimate
efficiency, low noise, at the highest quality standards.
We design the new Oil separation system for our LGFD air screw compressor that Compressors up to 132 kW are equipped with external separators that can be changed in a simple spin-off/spin-on process. Larger units have an internal separator cartridge. Due to the excellent separation efficiency of the system as a whole, the compressors can be used in the pressure range of 5.0 to 15.0 bar. Special pressures on request.
And the Oil circuit of our LGFD rotary screw compressor is the amount of oil in the units is determined in such a way as to extend the oil change intervals (depending on ambient conditions).An oil level sensor is integrated as standard and is read by the controller. All the units in this series have a horizontal oil separation vessel in which the oil is separated from the compressed air highly efficiently at low speeds.
