Does the oil-free screw air compressor have no oil at all?

Granklin oil-free screw air compressors are not absolutely oil-free, but their "oil-free" characteristics are achieved through advanced water lubrication technology. The following is a systematic description of technical principles, product characteristics and applicable scenarios:

principle of 1. Technology and Definition of "Oil Free"

1. water-lubricated compression technology
   • granklin oil-free screw air compressor adopts the compression structure of single screw plus star wheel, and uses pure water as lubricating medium to replace traditional lubricating oil. The water forms a lubricating film between the screw rotor and the star wheel, reducing friction while avoiding oil from participating in the compression process.
   • During the compression process, the water circulation system continuously provides lubrication and cooling for the compression chamber to ensure the efficient and stable operation of the equipment.
2. Analysis of "oil-free" characteristics
   • "Oil-free" means that no lubricant is actively added during the compression process and the oil content in the compressed air is extremely low. Since the water lubrication technology does not introduce oil, the compressed air quality meets the ISO 8573-1 CLASS 0 oil-free standard (oil content ≤ 0.01 mg/m & sup3;).
   • A very small amount of oil may come from the ambient air (such as oil mist in the atmosphere), but it can be further removed by the built-in high-efficiency filter of the equipment to ensure the cleanliness of the output air.

2. product features and benefits

1. clean compressed air
   • water lubrication technology completely avoid lubricating oil pollution, compressed air purity is high, suitable for medicine, food, electronics and other industries with strict air quality requirements.
   • Equipped with multi-stage filtration system, effectively remove the compressed air moisture, particles and trace oil, to ensure that the output air quality is stable and reliable.
2. High efficiency and energy saving
   • single screw plus star wheel design optimizes compression efficiency and reduces energy consumption. The water circulation system provides efficient cooling and reduces energy loss.
   • The frequency conversion control technology can automatically adjust the speed according to the gas consumption, further reducing the operating cost.
3. Low maintenance costs
   • there is no need to replace the lubricating oil, reducing the maintenance workload and the cost of consumables.
   • The equipment has a simple structure, strong wear resistance of key components, and prolonged service life.
4. Environmental protection and safety
   • as a lubricating medium, water is non-toxic and harmless to avoid environmental pollution caused by lubricating oil leakage.
   • The equipment has low operating noise and meets environmental protection requirements.

3. applicable scenarios

1. high cleanliness requirements industry
   • pharmaceutical Manufacturing: Used in drug production, packaging and other links to avoid oil pollution of drugs.
   • Food Processing: Used in food bottle blowing, packaging and other processes to ensure food safety.
   • Electronic Manufacturing: Used in the production of precision components such as semiconductors and circuit boards to prevent short circuits caused by oil.
2. Special Process Requirements
   • spraying industry: Provide clean compressed air to avoid coating defects caused by oil.
   • Laboratory: Used for gas supply of precision instruments to ensure the accuracy of experimental data.

4. user common misunderstanding clarification

1. "Oil-free" & ne; "Absolutely no oil"
   • grantklin oil-free screw air compressor uses water lubrication technology to control the oil content in the compressed air to a very low level (oil in the atmosphere), but it cannot completely eliminate all oil.
   • If completely oil-free compressed air is required, an additional adsorption dryer or catalytic oxidation device can be configured (through the post-processing equipment to filter the oil and particulate matter in the atmosphere).
2. Oil-free models are not "zero maintenance"
   • although there is no need to change the oil, it is necessary to change the filter regularly and check the status of the water circulation system to ensure the performance of the equipment.
   • Compressed air quality needs to be regularly tested to ensure compliance with industry standards.

5. selection recommendations

1. choose according to air quality needs
   • if the process requires extremely high air quality (such as medicine, food), granklin oil-free screw air compressor is preferred.
   • If the air quality requirements are not high (such as general power gas), you can choose the traditional model and configure the post-processing equipment.
2. Comprehensive consideration of initial investment and operating costs
   • grantklin oil-free screw air compressor has a high initial investment, but the later maintenance is simple and the operating cost is low.
   • Long-term operation can save lubricating oil replacement, oil cleaning and other costs, reduce the total cost of ownership.

Granklin oil-free screw air compressor takes water lubrication technology as the core, providing clean, efficient and safe compressed air solutions, and is an ideal choice for industries with high cleanliness requirements. Enterprises can choose suitable models and configurations according to actual needs to ensure the stability of the production process and product quality.
