Which is better, air compressor without oil or oil?

Many consumers in the purchase of air compressor, not only to face is the choice of variable frequency air compressor or choose the frequency air compressor problem, but also consider the air compressor is the choice of oil-free, oil, or micro oil, what is the difference between the three?

Air compressor is a mechanical equipment that provides power for the production line, which can be used in various production industries such as textile, laser cutting, and medicine. Although many production industries need air compressors, different industries have different requirements for air compressors.

For the ordinary production industry, the requirements for air compressors are not very strict. At this time, you can choose an air compressor with oil or micro-oil. After all, the cost of an air compressor with oil or micro-oil is different. And for some of the air compressor requirements are more stringent enterprises, such as laser cutting, medical and other industries, will be more stringent requirements on the air compressor, the need for air compressor can reach the standard of oil-free. This time to choose an oil-free air compressor.

During the purchase process, consumers will also ask whether it is better to have oil or no oil, and which life will be longer?

In fact, whether there is oil or no oil, it mainly depends on whether your production line is needed. Many production lines do not need oil-free air compressors, so you can choose oil-free air compressors, which can greatly save costs. As for which air compressor is more durable.

The first thing to be clear is that the life of the air compressor is not determined by oil or no oil. It depends on whether the air compressor of this brand has strength, whether the main engine of the air compressor uses high-quality materials, whether it is maintained on time during use, and whether it uses regular lubricating oil, filters, etc.

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 a special high temperature resistant material called Teflon or molybdenum disulfide 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.
