- Since there is no oil usage it is an enveronmentally friendly water lubrication compressor suitable for ISO 14000 certification.
- Direct-coupling , water lubrication , sealing , and cooling are the best in the class and high efficiency achieves lower maintenance work.
- Inverters for air-cooling fan motors are loaded as well. Capable of showing power Up enegy saving and the superior low noise property.
- ''The newly adopted IT touch panel enables smooth operation and control.''
