• An ideal energy saving compressor.
  • The compressing efficiency is drastically enhanced by the adoption of the compressor dedicatedly developed for each model.
  • Installation of the inverter realizes total energy saving.
  • There is no waste because the air of required pressure is taken only for the necessary volume with minimum power.
  • Although small, the direct-couple driving with the motor increases the air volume and reduces the maintenance work.
