Difference between oil free screw air compressor and ordinary air compressor

There are many types of air compressors, generally we customarily divided into oil free screw air compressors and oil-injected air compressors. What are the differences between the two except for the difference in lubrication methods? When it comes to oil free air compressors many people’s first reaction is that they do not contain oil, so but do you know what oil free screw machines run on? Oil free air compressors are usually used in some of the compressed gas quality requirements of high occasions, such as food processing plants, medical machinery, textile mills and so on. These occasions on the air in the oil content of the higher requirements, if the compressed air contains oil, or increase the defective rate of the product will also damage the air-using equipment. At this time it is necessary to use oil free screw air compressor to help production. With the development of various industries, the demand for oil free air compressors is also increasing.

There is no difference between the two from the construction point of view, the bearings are the same. But its working principle is different, oil free compressor work without the involvement of lubricant, mainly using pure water for lubrication. Ordinary oil-containing compressor is through the lubricant to lubricant, heat dissipation. So containing air compressor even if there is post-processing equipment but the compressed air more or less will carry part of the oil, so it is only applicable to part of the working conditions.

As we all know, air compressor high-speed operation process will produce a lot of heat, if this part of the heat can not be dissipated in a timely manner will lead to high temperature equipment. Ordinary air compressors generally need to use lubricant to reduce the temperature of the unit and reduce the friction of the components. So how does the oil free air compressor solve the problem of high temperature?

Oil free screw air compressor adopts pure water or other heat-conducting materials instead of oil, which solves the problem of high temperature of compressed air compressor and makes the air compressor realize high-speed operation.
