Product Description

Large Oil Flooded Rotary Screw Compressor / Mobile Screw Compressor


permanent magnet motor


Permanent magnet motor using high-performance NdFeB permanent magnet, 120 ℃ without losing the magnetic, life over 15 years.

Hollow coil with special frequency corona enameled wire, insulation performance, longer service life.

Can achieve soft start, run, the motor current will not exceed the full load current, at the same time, greatly reducing the impact on the grid equipment, electricity equipment will not cause damage.




1. World-leading "Made in Germany" Rotorcomp screw air end
2,25-30% energy saving than normal VSD compressor
3. wider 15-60hz adjustable-speed drive system
4. Intelligent touchable PLC control system
5. Double higher efficient VSD energy-saving motors in IE3 CE&MEPS




Shanghai rotorcomp Variable speed drive Screw Air Compressor adapting the amount of free air delivered to compressed air demand is the most economical operating method where demand for compressed air fluctuates considerably or where the stored volume is very small or where operating below peak load.

The benefits of rotorcomp VSD air screw compressor

>Smooth starts and stops within seconds
>Continuous volume flow regulation from 25-100%
>Adjustable-speed drive from 15-60hz
>minimization of wear and maintenance costs
>No power-peaks during start-up
> nearly no idling
