Air compressor with oil and oil-free difference

The main difference between oil and oil-free air compressors is reflected in the lubrication method, oil content, impact on the environment, use scenarios and later maintenance.

Lubrication method: Oil-free air compressors need oil to lubricate and cool during operation, while oil-free air compressors do not use lubricating oil.

Oil content: The oil content in the compressed air of the oil-free air compressor is extremely low, and it is generally believed that the oil content is 0.01ppm (I. e. 0.00001 mg/m & sup3;) or lower, reaching Class 0. The compressed air of the oil air compressor contains a certain amount of lubricating oil.

Impact on the environment: oil air compressor will discharge oil-containing gas into the air during operation, which may cause some pollution to the environment. The oil-free air compressor does not have this problem, and its emissions are cleaner and more environmentally friendly.

Use scenario: Oil-free air compressors are mostly used in occasions with high air quality requirements, such as food, medicine, electronics and other industries. The oil air compressor is widely used in a variety of air quality requirements are not too strict occasions.

Post-maintenance: Oil-free air compressors need regular replacement of lubricating oil and maintenance work such as oil cleaning, while oil-free air compressors save these troubles, and maintenance costs are usually low.

In addition, there are differences in cooling methods between oil-free air compressors and oil-free air compressors. Oil-free air compressors generally use air-cooled or water-cooled air compressors to cool, while oil-free air compressors can be cooled by lubricating oil. In terms of price, the manufacturing cost of oil-free air compressor is usually higher than that of oil-free air compressor, so its price is relatively high.

In general, oil-free air compressors and oil-free air compressors have their own advantages and disadvantages. Which type of air compressor should be considered comprehensively according to the specific usage scenarios and needs.
