The difference between oil-free air compressor and micro-oil air compressor

With the widespread use of oil-free air compressors, micro-oil air compressors have gradually entered people's field of vision. Oil-free air compressors, as the name implies, produce compressed air completely free of oil; micro-oil air compressors, The compressed air produced contains oil, but the content is very low. The following small series will introduce the difference between oil-free air compressor and micro-oil air compressor.

Whether lubricating oil is needed: oil-free air compressors do not need lubricating oil at all, while micro-oil air compressors will need lubricating oil.

2, compressed air quality: oil-free air compressor can ensure that 100 of the compressed air discharged does not contain lubricating oil, and micro-oil air compressor can not do this, so the former compressed air quality is higher.

3. Application: Micro-oil air compressor is generally used in ordinary industrial production; oil-free air compressor is generally used in food, beverage, pharmaceutical and other occasions that require very high quality of compressed air. This is mainly due to the quality of compressed air.

4, manufacturing materials and process requirements: oil-free air compressor needs to use water to lubricate the air compressor head, for the manufacturing materials, process requirements are higher. The micro-oil air compressor does not use water lubrication, and the requirements for the manufacturing process are not so high.
