- 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 air of required pressure is taken only for necessary volume with minimum power.
- Although small, the direct-couple driving with the motor increases the air volume and reduces the maintenance work.
