ZU905WS2 / ZU906WS2


- The environmentally friendly water lubrication compressor without using oil at all (ideal for ISO 14000).
- In addition to the direct-coupled driving, thanks to the water lubrication system in which the water performs lubrication, sealing and cooling, the efficiency is further enhanced to the highest in its class, thus saving the maintenance work.
- Low noise, less vibration, slower rotation, and low temperature.
- Optimum for plants and large-scale factories.
