What is the difference between oil-free air compressor and micro-oil air compressor

In recent years, many basin friends with working pressure are discussing the problem of "which is a better oil-free air compressor or micro-oil air compressor. In fact, this kind of problem can not get a proactive response, because these two kinds of air compressors have their own advantages. For example, if A natural environment has high regulations on compressed air, oil-free air compressors can be applied. If B natural environment does not have high regulations on compressed air quality, we can select and apply micro-oil air compressors according to the core concept of cost saving.

To put it bluntly, the oil-free air compressor means that the compressed air produced by it is all oil-free; and to put it bluntly, the compressed air produced by the micro-oil air compressor is oil-free, but the composition is very low.

Below, we carry out data analysis on 2 models: You can try to purchase Granklin water-lubricated air compressor, our air compressor can provide high-quality compressed air.

1. compressed air quality: oil-free air compressor can ensure that all the compressed air discharged without lubricating oil, and micro-oil air compressor can not guarantee this, so the previous one has higher compressed air quality.

Main uses of the 2.: micro-oil air compressor is generally used for general industrial production; oil-free air compressor is generally used for food, beverage, pharmaceutical and other places with high quality of compressed air. This is mainly due to the quality of the compressed air.

Regulations on 3. making materials and processing technology: oil-free air compressors need to use self-lubricating bearing materials, and the regulations on making materials and processing technology are relatively high. The micro-oil air compressor does not require the application of self-lubricating bearing materials, and the processing technology is not high.

4. requires the application of lubricating oil: oil-free air compressor does not require lubricating oil at all, and micro-oil air compressor requires lubricating oil.

5. the price is not the same: under the same specification, the oil-free air compressor is more expensive and more expensive.

The oil-free air compressor reduces the steam to the outside, which is not easy to greatly reduce the motor load due to the loss of working pressure caused by the oil drainage machine equipment, and reaches the actual effect of low carbon and energy saving. Oil-free air compressor can work without filling any lubricating oil. The discharged gas is oil-free, which can alleviate the confusion of oil on natural gas equipment and the environmental pollution of secondary commodities. Ecological environment protection and social and economic benefits are very good. It can be checked twice a day, making application and maintenance more convenient.
