Air CompressorZ series
Z series
Z755WS2-R / Z756WS2-R
- 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)
