Performance Advantages

1. High Energy Efficiency and Energy Saving

Industry-leading specific power, significantly reducing long-term operating power consumption.

2. Low Noise and Vibration

Highly dynamically balanced rotor and precision bearings ensure smooth operation, with noise levels lower than industry norms.

3. Long Lifespan and Low Maintenance

Rotor surface hardening treatment (e.g., DLC coating), bearing life exceeding 60,000 hours, requiring only periodic oil and filter changes.

4. Wide Operating Condition Adaptability

Supports high pressure (8–40 bar) and wide temperature environments, suitable for harsh industrial scenarios.
