1. Silent and low noise
Rotary screw air compressor with permanent magnet motor and variable speed features lower noise compared with the normal air compressor. Because most rotary screw air compressor is running under speed which is lower than the rated speed. So there is small abrasion. Thus there is small noise. And the service life of the compressor is prolonged.
2. Low maintenance cost
The rotary screw air compressor adopts highly efficient and energy saving control system. So the damage from the compressor to the power grid and machine is greatly reduced. The service life of various parts is further prolonged. So the maintenance cost of the rotary screw air compressor is generally lower than normal air compressor.
3. Long term and stable running
The rotary screw air compressor has energy saving control system with high intelligence which can monitor many parameters at the same time such as electric current and voltage etc., ensuring the air system can be long termly stable and reliable.
4. Variable-displacement control
The air compressor adopts power frequency drive features stable air displacement while the rotary screw air compressor features variable air displacement. The motor speed can be adjusted at real time according to the practical air consumption by frequency converter so that the air flow can be controlled. When the air consumption is low, the air compressor will automatically sleep. So the energy consumption will be greatly reduced. The optimizing of control strategy can improve the energy saving effect.
