Is it better to have oil or no oil in the air compressor

Good or bad depends on the occasion of use and the actual working conditions.

In some cases, such as food, medicine, precision instruments and other industries, it is necessary to use a full oil-free air compressor.

But the oil-free air compressor is much more expensive and the maintenance cost is higher.

If it is used for purging, machining, manufacturing and power use, it is possible to choose an air compressor with oil and micro oil. Such as spraying, steel, electricity, hardware, mining, ceramics, textiles, machinery, etc. are widely used.

The difference between oil and no oil

oil and no oil in the air compressor generally refers to the amount of oil content in the gas discharged from the exhaust port of the air compressor. Generally, the oil content of the oil machine is relatively large, and the oil content of the oil-free oil machine is 0.01ppm. Therefore, the oil content is used to distinguish the oil and no oil in the air compressor.

At present, the air compressor model with large displacement and full oil-free can adopt the scheme of water lubricated screw air compressor.
