Is the air compressor oil-free or oil-free?

Air compressors with oil and without oil are not absolutely good or bad. Their use occasions are different from those suitable for working conditions. If they are used for purging, mechanical processing, manufacturing and power use, it is OK to choose air compressors with oil and micro oil. However, oil-free air compressors must be used in some occasions, such as food, medicine, precision instruments and other industries. Oil-free air compressors are cleaner and more environmentally friendly than oil-free air compressors to some extent, but oil-free air compressors are more expensive than oil-free air compressors and have higher maintenance costs.

In addition to the price, oil-free air compressor and oil air compressor has the following differences:

1. The oil content is different. Generally, the oil content of the oil machine is larger, and the oil content of the oil machine is 0.01ppm, so this oil content is used to distinguish the air compressor with oil and without oil. There is also a completely oil-free air compressor, which is lubricated with resin materials, so the final discharge of gas does not contain oil, called a completely oil-free air compressor.

2. The structure is different. Whether it is an oil-free piston machine or an oil-free screw machine, a large amount of high temperature will be generated during the operation. The participation of oil in the air compressor will take away the high temperature generated during the compression process of the air compressor, thereby Cooling the machinery. The oil-free air compressor uses water as a cooling material to replace the oil to solve the high temperature in the compression process of the air compressor, thus achieving the purpose of oil-free compression.
