• An upgraded, dedicated compressor for each model.
  • The totally enclosed fan cooled motor is adopted for all models.
  • The direct-couple driving system eliminates kinetic loss and bending stress.
  • Extended maintenance cycle, simplified maintenance work.
  • The discharge air volume is increased by 5%. Low noise, less vibration (best balance with slower rotation)
