What is a precision compressed air filter

Compressed air is an indispensable source of power in human life and industrial production, in life, such as blue, volleyball, soccer and a variety of car tire inflation, pump application is compressed air; for example, industrial production of stamping, welding, painting, assembly, printing and other processes need to use compressed air. dpc for your introduction.

With the continuous development of modern industry, people's requirements for the quality of compressed air are getting higher and higher, especially the needs of the production process, making companies pay more and more attention to the quality of compressed air. Modern industry requirements for compressed air can be divided into the following areas:

1, compressed air pressure, flow requirements:

In almost any place where compressed air is needed, there are certain requirements for the pressure and flow of compressed air. Currently the most common pressure value at about 0.7MPa (g). But in some special occasions such as the glass industry, the compressed air pressure requirements may be 0.2-0.4MPa (g) or so; and in some military enterprises, for example, the compressed air pressure requirements in the tens of MPa or so. How to meet these requirements? Now there are a variety of air compressors on the market can be achieved.

2, the requirements of compressed air dryness:

Dryness is said to be the water content of compressed air or dew point temperature. Different processes on the compressed air dew point temperature requirements are different, such as the compressed air pressure dew point used for instrumentation generally requires less than -40 ℃, while in some precision instruments, such as industrial robots, automatic assembly lines, automotive spraying and other industries on the compressed air pressure dew point may require between -40 ℃ to -70 ℃. But for some simple blowing or pumping compressed air is not much required. The dew point size of compressed air is usually achieved by the dryer. Pressure dew point above 0 ℃ can use refrigerated dryer, pressure dew point in -20 ℃ to -70 ℃ is better to use adsorption dryer.

3, the requirements of compressed air cleanliness:

As the air contains a lot of oil mist, microorganisms, solids, dust and harmful gases, etc.. These have some damage to the machine. How to remove these substances? Compressed air filters can be used to solve.


Compressed air filter is a device for filtering and purifying compressed air. We generally refer to the high efficiency precision filter in the compressed air system pipeline.

As a barrier for the screw laser cutting air compressor, the quality of the air filter is crucial. If the air filter is not of good quality, just like people, disease enters through the mouth. If the air filter is of bad quality, customers will waste a lot of electricity and directly affect the service life of oil, oil filter, oil and bearings. However, air filter quality is an issue that many so-called masons in the screw laser cutting air compressor industry ignore. Many people do not pay attention to the quality of the air filter. Only when the air filter is sucked to deformation, they know the air filter quality is poor, and he doesn't know what causes the deformation, just know to replace it with a new one and be done with it.

It is not particularly difficult for an air filter to have good waterproof performance. As long as you use good wood pulp filter paper, you can meet the requirements, but the production cost will be slightly higher. It is more difficult to meet both filter accuracy and air permeability. It is a good air filter that can meet all three requirements at the same time. I also hope you can remind customers to clean the air filter diligently, which is not only to better protect the screw air carrier. It is also to help customers save electricity (dust attached to the surface of the air filter will affect the smooth inhalation). Users with particularly harsh environments should also sort out the air filter once a day and replace it once in 500-800 hours, while customers with medium environments clean it once in 3-7 days and replace it once in 1000-1500 hours. Customers with good environment! Replace the air filter every 500-2000 hours.
