Authentic Reliable Quality Naturally Stands Out

· Los Noise: ≤80dB
· Micro Oil: ≤3ppm
· Oil Free: 100% Oil-free
· Permanent Magnetvariable Frequency(Centrifugal Technology): 20% ~ 100%

  • Magnetic Bearing Technology

    Integrated design of machine head and motor.

    Permanent magnet synchronous motor.

    Frequency conversion technology.

  • High-Speed Pm Motor Technology

    The direct-drive rotor of the high-speed permanent magnet motor eliminates the need for a speed-increasing gear structure, thereby improving transmission efficiency.

    The rotor utilizes rare-earth permanent magnets for excitation, with third-party testing confirming a motor efficiency of over 97%.

    The unique high-strength carbon fiber binding technology, validated through a 115% overspeed test, ensures the reliability of the rotor's permanent magnets at high speeds.

  • Typeinverter Technology

    Compressed air naturally flows back from the high-pressure end to the low-pressure end, with higher compression ratios leading to greater leakage. Under the same power and discharge pressure, two-stage compression significantly reduces backflow leakage compared to single-stage compression, greatly improving volumetric efficiency and achieving a 10–15% increase in output.

    The variable frequency design better aligns with customers' air usage needs.

  • High-Efficiency Fluid Machinery Technology

    The new-generation rotor is designed for improved compliance with fluid dynamics.

    The overall machine design undergoes CAE finite element analysis to ensure energy efficiency and stability.
