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.
