What is the oil content in the exhaust gas of an oil-free air compressor

Explanation on oil content in exhaust gas of Granklin oil-free lubrication screw air compressor

Granklin air compressor adopts water-lubricated single screw and star wheel compression technology, and its core design completely abandons the traditional lubricating oil system. This technology achieves sealing and lubrication between the rotor and the star wheel plate through water medium, preventing lubricating oil from participating in the compression process from the source. Therefore, the equipment exhaust does not contain any lubricating oil components, and the cleanliness of the compressed air reaches the industry oil-free standard, which can meet the needs of application scenarios sensitive to oil content.

Technical principles and advantages

  1. Oil-free compression mechanism: Sealing and lubrication in the compression chamber are completed only through water circulation, and no lubricating oil comes into contact with the compressed air, fundamentally eliminating the risk of oil pollution.
  2. material compatibility: Key components are made of corrosion-resistant materials to ensure long-term stable operation of aqueous media and avoid introducing impurities due to material precipitation.
  3. Cleanliness guarantee: The oil content in the exhaust is close to zero, which meets the strict requirements for compressed air in high-clean industries such as medical, food, and electronics.

applicable scenarios
This technology is suitable for areas that require pure compressed air, such as:

  • Medical equipment and pharmaceutical processes
  • Food packaging and beverage production
  • Precision electronic component manufacturing
  • Laboratory analysis and instrumentation

Granklin air compressors provide users with reliable oil-free compressed air solutions through innovative water lubrication technology, helping to achieve industrial upgrading and environmental protection and energy conservation goals.

Welcome!
