There is no difference between oil and oil in the gas blown by the air compressor.

The air blown by the air compressor can be divided into oil and oil-free. The main difference between them is the oil content in the compressed air.

During the compression process of the oil air compressor, the lubricating oil will be in direct contact with the air, so the compressed air will contain a certain amount of oil. These oil components may exist in the form of oil mist or oil droplets, which have a certain impact on the quality of compressed air. Especially in some applications with high air quality requirements, such as food, medicine, electronics and other industries, the oil-containing gas blown by the oil air compressor may not meet the production requirements.

Oil-free air compressor adopts a special lubrication method, so that the lubricating oil will not directly contact with the compressed air, thus greatly reducing the possibility of oil entering the compressed air. Therefore, the oil-free air compressor blowing gas oil content is low, but not completely free of oil, its oil content is affected by the region, air quality, air compressor room environment, compressor cleanliness and other factors. However, compared to oil-free air compressors, oil-free air compressors are more suitable for applications with higher air quality requirements.

In addition to the difference in air quality, oil and oil-free air compressors also have certain differences in structure, performance and maintenance. For example, oil-free air compressors usually require the use of higher-level seals and bearings and other components to ensure that there is no leakage of lubricating oil during the compression process; while oil-free air compressors require regular replacement of lubricating oil and oil filters and other components. Maintain its normal operation and extend its service life.

Therefore, when choosing an air compressor, it is necessary to choose a suitable oil or oil-free air compressor according to the specific application and requirements. If the air quality requirements are high, it is recommended to choose an oil-free air compressor; if the air quality requirements are not high, and you want to reduce costs and maintenance workload, you can choose an oil-free air compressor.
