Working Principle of Oil-free Scroll Air Compressor


  • Air compression processes which is realized by the movement of rotor and stator. The air is sucked fromthe side of air-end, rotor seals the compression chamber and air is compressed gradually along with rotoimovement and compression chamber become smaller. Compressed air is discharged from the center ofstator. This is a continuous processes, the discharged compressed air is smooth and no fluctuation.
  • The movement of rotor refer figure 1-4 (suction – compression – exhaust). The suction air is graduallycompressed in the smaller and smaller compression chamber due to rotor and stator movement, at last thecompressed air is discharged from the center discharge hole.

Oil-Free VS Traditional Belt-Type Scroll Air Compressor


CategoryTraditional Belt-Driven Scroll Air Compressor
  • Host: Patented technology, square design, easily reaches 1.25Mpa pressure.
  • Motor: It uses the most energy-saving permanent magnet motor with an efficiency of over 91%.
  • Control panel: It uses a four-line LCD display control panel to display the operating pressure in real time, as well as various early warnings, alarms and maintenance prompts. A 9-inch touch screen is used for more than three hosts.
  • Host: The host is traditionally designed, and the maximum pressure can only reach 1.0Mpa.
  • Motor: It uses ordinary motors with low efficiency, only 84%.
  • Control panel: It uses a control panel in the form of a semiconductor light-emitting digital tube. It can only display pressure, and other displays can only rely on codes.
    Oil UsageDoes not require oil for lubrication, making it suitable for applications where oil-free air is necessary, such as food and pharmaceutical industries.Requires oil for lubrication, which can contaminate the compressed air. Additional filtration or separation systems may be needed to ensure oil-free air output.
    MaintenanceLower maintenance due to the absence of oil changes and related components.Higher maintenance due to regular oil changes, filter replacements, and potential issues with oil leaks or contamination.
    Energy EfficiencyOften more energy-efficient due to direct drive technology and fewer moving parts, leading to less energy loss.Less energy-efficient compared to oil-free models, as energy is lost in the belt drive system and through friction in oil-lubricated components.
    Noise LevelTends to operate quieter due to the design that minimizes vibrations and the lack of a noisy belt drive system.Can be noisier due to the operation of the belt drive system and potential vibration from oil-lubricated components.
    CostInitial cost can be higher due to the specialized design and components required for oil-free operation.Generally lower initial cost but potentially higher operating costs over time due to maintenance and energy consumption.
    Air QualityProvides high-quality, clean air free from oil contamination, ideal for sensitive applications.Air quality depends on the efficiency of the filtration system; there's a risk of oil carryover if not properly maintained.
    ApplicationsSuited for industries with strict air quality standards like food processing, medical, and electronics manufacturing.Suitable for general industrial use where oil contamination is not a concern, such as automotive workshops and construction sites.
    DurabilityLong lifespan due to reduced wear from the absence of oil and fewer moving parts.Durability can vary; belt and oil-related components may degrade over time, requiring replacement.

    Application of Oil-free Scroll Air Compressor

    air supply bus

    Electric bus air supply solution

    In electric buses, oil-free scroll air compressors play a key role in providing clean, dry compressed air for the vehicle's braking system, door control system, and pneumatic tools. As electric buses have strict requirements on environmental friendliness and operating efficiency, the oil-free design can ensure air quality and avoid potential damage to electrical components and braking systems caused by oil pollution. At the same time, its high efficiency and low noise characteristics also meet the needs of urban bus operations.

    High-speed rail air supply solution

    The pneumatic system of high-speed rail trains requires a highly reliable compressed air supply for brake control, door operation, and internal equipment in the carriage.
