Screw air compressor belongs to what kind of container

The screw air compressor itself is not classified as a container, but as a type of compressor. A container usually refers to a closed device used to store a gas, liquid or solid, such as a gas storage tank, a liquid storage tank, etc. Screw air compressor is a device that compresses gas through the rotation of the screw, so it belongs to the compressor category.

Regarding the water-lubricated oil-free frequency conversion screw air compressor of Shanghai Granklin Group, within the power range of 7.5-250KW, the equipment adopts water lubrication system and frequency conversion control technology. The water lubrication system makes the air compressor do not need to use lubricating oil during operation, thus avoiding the risk of oil pollution and ensuring that the output compressed air is pure and oil-free. The frequency conversion control technology enables the air compressor to intelligently adjust the output according to the actual demand and improve the energy efficiency.

Question: How does the water-lubricated oil-free frequency conversion screw air compressor of Shanghai Granklin Group keep the compressed air pure and oil-free during operation?

Answer: Shanghai Granklin Group's water-lubricated oil-free variable frequency screw air compressor uses a unique water lubrication system to keep the compressed air pure and oil-free. In a conventional oil-lubricated screw air compressor, the lubricating oil is carried into the compression chamber and mixed with the compressed air, resulting in oil contamination. However, in water-lubricated systems, water is used as a lubricant, completely replacing the lubricating oil. The water is not mixed with the compressed air during the compression process, but is discharged from the system after the compression is completed. Therefore, the water lubrication system can completely eliminate the risk of oil contamination and ensure that the output compressed air is pure and oil-free. In addition, the Shanghai Grankering Group also uses high-quality seals and materials to further prevent any possible oil or other contaminants from entering the compressed air system.
