Micro oil screw air compressor Micro oil What does micro oil mean

The “micro-oil” in “micro-oil screw air compressor” means that the equipment uses only a very small amount of lubricating oil during operation, achieving efficient cooling and sealing through precise lubrication system design, while significantly reducing oil pollution in the compressed air. The following is a detailed explanation:

1. technical principle

  • micro-lubrication
    Different from traditional oil-injected air compressors, micro-oil screw air compressors passHigh-precision injection system, spray a trace amount of lubricating oil into the compression chamber in an atomized form. The amount of oil is usually controlled below 10% of that of traditional equipment, which can not only meet lubrication and cooling needs, but also avoid excessive oil residue.
  • Oil and gas separation technology
    The compressed air passes through a high-efficiency oil-gas separator, which can recover more than 90% of the lubricating oil, further reducing the oil content discharged into the air (usually less than 0.01mg/m³), which is much higher than the general industry standard (5mg/m³).

2. core advantages

  • High air quality
    It is suitable for food, medicine, electronics and other scenarios that require strict cleanliness of compressed air, and complies with ISO 8573 CLASS0 standard (oil content <0.01mg/m³).
  • energy conservation and environmental Protection
    Lubricating oil consumption is reduced by 80%-90%, reducing energy consumption and carbon emissions; at the same time, friction loss is reduced by about 30%, extending equipment life.
  • low maintenance cost
    There is no need to replace lubricants and filters frequently, simplifying the maintenance process.

3. application scenarios

  • high temperature and high humidity environment
    The micro-oil design enhances sealing performance, adapts to hot and humid climates such as Asia, and prevents emulsification of lubricating oils.
  • Industries sensitive to air quality
    Such as medical device production, semiconductor manufacturing, packaging and printing, etc., to avoid oil pollution affecting product quality.

4. Comparison with traditional air compressors

characteristics Micro-oil screw air compressor Traditional oil injection air compressor oil free compressor
lubrication method Micro-atomizing injection Heavy injection lubrication No oil or small amount of isolation lubrication
oil content <0.01mg/m³ 5-10mg/m³ Close to 0 (but bearings need lubrication)
maintenance costs Low (high oil recovery) Higher (high oil consumption) High (requires special material maintenance)
applicable scenarios Food, medicine, electronics, etc.(some scenarios) General industrial gas supply Extreme cleaning needs, food, medicine, electronics, chemicals, etc.(such as laboratories)

summary

“Micro-oil” technology accurately controls the amount of lubricating oil, taking into account equipment stability and air cleanliness, making it the preferred solution to balance cost, efficiency and environmental protection needs.
