- An upgraded, dedicated compressor for each model.
- The totally enclosed fan cooled motor is adopted for all models.
- Although small, the driving method directly coupled with the motor increases the air volume and saves maintenance work.
- No accelerators such as belts or gears.
- Optimaum balance with less vibration and less rotation.
