These Misunderstandings You Need to Know

1. Compressed air produced by oil-free air compressors is oil-free
Although oil is not used in the compression chamber, the oil does not come into contact with the compressed air,.But the oil vapor contained in the atmosphere cannot be removed.
This causes a small amount of oil impurities to be contained in the compressed air. The oil content in the compressed air produced by the oil air compressor.
It has a very close relationship with the air quality. Air compressor room environment and compressor cleanliness.

2. Oil-free air compressor does not use oil

Although oil is not used for air contact during compressed air. However, oil is still used to cool the compressor and lubricate the operating components for normal and stable operation of the compressor.

3. The compressed air produced by the oil-free air compressor is non-polluting

There are many pollutants in the atmosphere, including dust, water vapor, oil vapor and microorganisms. Compressed air produced by an oil-free air compressor. It only ensures that the oil does not enter the compressed air during the compression process.
However, the hopper in the air itself cannot be removed. This means that the compressed air produced by the oil-free compressor is not necessarily pollution-free. The use of air treatment products helps to reduce pollution to the required level.

5. The cost of oil-free screw air compressor is low

In fact, because the compression ratio is much smaller than that of an oil-lubricated compressor, the energy consumption is higher. The same power oil-free machine has less than 40% gas production than the energy-saving screw compressor. Although the compression chamber is not lubricated with oil. However, grease and air filtration in other parts still require regular maintenance. The core rotor is generally treated with a special coating and has a service life. The water requirements are high and easy to damage. The maintenance of the main engine is a must for the oil-free machine, which can account for 50% of the equipment cost.

We believe that for most users, it is not necessary to really class zero oil-free compressed air.  Solving the problem of oil impurities caused by dehydration dryers, non-thermal regenerative dryers, micro-heat regenerative dryers, etc. Contamination of equipment, preventing the efficiency of post-treatment equipment from degrading or even losing the choice of water removal function. For users who need genuine Class zero oil-free compressed air. It is difficult to obtain oil-free compressed air stably and continuously for oil-free air compressor alone. It is still necessary to configure the corresponding degreasing equipment.
