Features
Application
Download
  NZ3000 series VFD can adjusting the rotary speed according to the needed quantity of air and it can save more energy compared to the machine without the inverter to control its rotary speed. Besides, comparing with the general-used machine with an inverter, equipped with high-efficient permanent-magnet motor can save the 6%~7% of the energy, especially  in the area of low loading, its outstanding control range and structure can show obvious   advantage in energy-conservation. Compared with the common power frequency air compressor, magnetic variable frequency air compressor which can play the highest energy efficiency in a wide range will save the energy of 42%.
