Scroll Compression Principle

Composed of a pair of intermeshing orbiting and stationary scrolls, the orbiting scroll rotates eccentrically around the stationary scroll, compressing the gas within the gradually shrinking vortex chamber and ultimately discharging it through the central exhaust port. This process is continuous and smooth, with minimal vibration and noise.

Unique Advantages of Oil-Free Scroll Compressors

  • 100% Oil-Free Air

    The compression process requires no lubricating oil, resulting in pure air output that meets ISO 8573-1 Class 0 standards.

  • Low Noise and Vibration

    The scroll structure operates smoothly, typically below 60dB, making it suitable for quiet environments.

  • High Energy Efficiency

    Low leakage and high volumetric efficiency yield approximately 30% energy savings compared to piston compressors.

  • Low Maintenance

    No oil system, reducing maintenance costs such as oil and filter changes.

  • Compact Structure

    Small size makes it suitable for applications with limited space.


Typical Applications 

  • Medical Industry: Respirators, Dental Equipment.

  • Food & Beverage: Packaging and Filling Lines.

  • Electronics Manufacturing: Chip Production, Precision Instruments.


FAQ

Q1: What is the lifespan of an oil-free scroll compressor?

A: The core scroll typically has a lifespan of over 40,000 hours, but the air filter and seals require regular replacement.


Q2: Can it replace an oil-filled air compressor?

A: It is suitable for applications requiring high air quality, but for high power (>30kW) or large flow requirements, an oil-free screw compressor is recommended.


Q3: Is post-processing equipment required?

A: A refrigerated dryer or filter is still required to remove moisture and particles, but an oil filter is not required.


Q4: Does temperature rise affect performance?

A: The temperature rise of a scroll compressor is relatively low (<90°C), but in high-temperature environments, improved heat dissipation or derating are required.
