The air compressor can be classified into oil-free air compressor and oil-free air compressor according to the lubrication mode. How can we choose the air compressor suitable for our needs? What is the difference between oil-free air compressor and oil-free air compressor?

1. From internal structure

Oil-free air compressor is a relatively simple equipment, which does not need to use any lubricant, but only consists of fan, cylinder, connecting rod, gear, reducer and other parts. Oily air compressor is a complex device, which requires the use of specific lubricants to ensure its efficiency.

2、.From the perspective of oil content

Oil and no oil in the air compressor generally refers to the oil content of the exhaust body of the air compressor. There is also an oil free air compressor, which is not lubricated with oil, but lubricated with resin material. Therefore, the final gas discharged without oil is called an oil free air compressor.

3. From the perspective of working principle

There are obvious differences between the two. There is no oil involved in the operation of oil-free air compressor. Whether it is oil-free piston engine or oil-free screw engine, they will produce a lot of high temperature during the operation. If there is oil involved in the operation of oil-free air compressor, it will take away the high temperature generated in the compression process of the air compressor, thus cooling the machine.

The oil-free air compressor is a more energy-saving and environment-friendly air compressor, which does not need to use lubricating oil to ensure its normal operation, while the oil-free air compressor needs to use lubricating oil. Therefore, oil-free air compressor can reduce the impact on the environment, save energy consumption and work in a quiet environment. Therefore, hospitals, laboratories and schools are very suitable for choosing oil-free air compressor.
