Air compressor is a machine equipment that compresses air and transfers energy. It is widely used in various industries, mainly in two types: volumetric and dynamic. Among the types of positive displacement compressors, traditional piston compressors are gradually being replaced by screw compressors, while oil immersed (oil injected) screw compressors dominate the market due to their high efficiency and cost-effectiveness.
The lubricating oil for air compressors has the following performance requirements: lubrication (bearings, pistons, valves, cylinders, screws, gears, etc.), sealing, and cooling. Due to the high temperature rise of compressed air, ordinary mineral oil is prone to oxidation reactions under high temperature and moisture conditions, generating organic acids, paint films, sludge, and carbon deposits. Moreover, after air cooling, water vapor condenses into water, which may cause corrosion or lubricant dissolution. As a result, compressor oil deteriorates rapidly, its service life is shortened, and it is easy to damage the compressor
It is crucial to choose high-performance compressor lubricating oil as it can cause damage to machine components. Worldwide, the use of high-performance air compressor oil, especially synthetic air compressor oil, has become a trend.
Providing a professional manufacturer of high-performance air compressor oil, Ruifu Group offers a range of synthetic air compressor lubricants by blending high-quality synthetic base oils with selected additives.
