Overall Energy saving

Compared with powered fixed air compressor, variable speed air compressor has practicalsignificance in energy saving.

costThe variable speed air compressoroffers precise pressure control,quickly responding to changes byadjusting the motor's speed. Itmaintains pressure fluctuationswithin ±0.1 bar, stabilizes the pipenetwork's pressure, optimizes airvolume, and minimizes energy loss.

A variable speed air compressoruses frequency conversion forsmooth startup, eliminating peakcurrent from star-delta methods.This reduces starting power,minimizes impact on the power gridand equipment, and lowersoperational noise.

Variable speed control surpassesstandard throttle control, offeringa wider flow rate adjustmentrange. When paired with a high-efficiency permanent magnetmotor, it provides greater energysavings at lower flow rates.

  • Most of the cost in the life cycle of the air compressor is generated by the electricity it consumes.
  • The power consumption of the compressor is closely related to the on-site air planning.
  • The variable speed air compressor can not only ensure smooth production, but also save considerableelectricity costs and achieve a win-win situation for the enterprise.

Using less power to provide more compressedair as well as larger range of air volumeadjustment, 15%-38% savings on electricitycomparing with ordinary constant frequencymachine, and 5%- 10% to ordinary variablefrequency machine. More obvious effect ofenergy saving where the greater fluctuation ofair use.

  • High efficiency PM motor saves energy 6–7% comparing with common 3-phaseasynchronous motor.
  • Adopts latest air end and 1-shaft structurefor more compact, stable and efficiency.
  • Use intelligent inverter technology, PM VFcompressor saves energy up to 30%.
  • Owns numbers of patented technologies.
  • Industrial LOT functionality.
