- Z-screw compressor made by our precise machining technology which has experience of more than 70 years achieves the best balance available in the industry.
- The body layout can be made compact owing to the direct-couple driving. The compressor and the motor are directly coupled and driven, without using belts or accelerators, thus eliminating energy loss.
- Compressors are developed dedicatedly for each model, realizing the largest discharge air volume in its class. To achieve the best efficiency, the compressor which best matches each motor output is selected and installed, thus achieving energy saving.
