The oil-free screw air compressor uses pure water to lubricate the unit and cool the compressed air. Therefore, the quality of the gas compressed by the oil-free screw compressor is relatively high.

　　 As everyone knows, the oil-free screw air compressors that everyone sees in normal work are also equipped with post-processing equipment. Why is this?

　　 Many customers are more confused.

　　Generally speaking, the key post-processing equipment that everyone often says includes gas tanks, dryers, and precision filter equipment. Everyone knows that air pollutants such as dust, water, and impurities will appear in general compressed air, and the role of post-installation treatment is to filter out such air pollutants. The role of this post-processing equipment is different. Let's explain in detail the function of each post-processing equipment.

　　1, precision filter

　　 Its function is to filter out air pollutants such as dust, water, and various floating solid particles in the air.

　　2, gas tank

　　(1) Store compressed air.

　　(2) Buffer the working pressure, the oil-free screw air compressor can be installed with a gas storage tank to maintain the gas source pressure within a certain range, so that the compressed gas pressure will be relatively stable and not prone to large fluctuations.

　　(3) Cooling air. Compressed air generally has a higher temperature. After high-temperature compressed air is refrigerated in the air storage tank, condensate will be produced. Therefore, the water in the air storage tank must be discharged on time.

(4) Maintain the air compressor. After a certain amount of gas is stored in the gas storage tank, the air compressor will automatically stop, which can reduce the frequent start and stop of the generator set, the loss of various components, and also prevent the unstable gas source from damaging the gas. equipment.

　　3, dryer

　　 The key function is to remove moisture from compressed air. There are two key types of dryers in the market: refrigerated dryers and suction dryers. Generally, there are more customers who use refrigerated dryers.

This is why oil-free screw air compressors must also be equipped with post-processing equipment. How to choose the size of the post-processing equipment, you can consult the corresponding salesman.
