Product Description

LED Display VSD Screw Compressor With Super High Efficient Inverter Motor




permanent magnet frequency converter

Pneumatic stability: As the frequency of the screw air compressor using the inverter's stepless speed characteristics, through the controller or the inverter inside the PID regulator, can start gently; on the gas fluctuations in the larger occasions, but also fast Adjust the response.

Start without impact: As the inverter itself contains the soft start function, the starting current maximum rated current within 1.2 times, and the frequency of the general start in the rated current of more than 6 times compared to start the impact of small; Not only the power grid, the impact of the entire mechanical system, but also greatly reduced.



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
6. Unique driving guard system
7. ISO, TUV, GA, CE,SGS certificates




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


Permanent magnet synchronous drive straight association-like host advantages


1.high efficiency and energy saving response speed bearing less motor shaft current


Frequency conversion control technology characteristics


With vector control technology is particularly prominent advantages 1. energy saving effect is remarkable

2.variable flow control, gas supply stability 3.Soft Start: Start no impact


Equipped with highly efficient permanent magnet motor (PM motor),compared with ordinary frequency modulation motor, energy-saving performance is more outstanding!


Especially when the motor speed is low, the permanent magnet motor can still keep high efficiency

Reduce Energy Consumption

The costs of power consumption account for 70% or more of all costs during the operation. The electric charges of running air compressor account for more than 40% of all the electric charges in the factory.

The requirement of compressed air fluctuates violently in different time every day, different weeks, or different months every year. The range of fluctuation is 40% to 80%, Rotorcomp adjustable-speed drive screw compressor can meet the user’s requirement exactly. When the user needs less air delivery, Variable frequency inverter can reduce the capacity and reduce the power consumption at the same.
