In the air compressor system, we will find that the filter is one of the indispensable after-treatment equipment, but the location of their installation is different, the reason is because the function of these filters is different, because each installation position of the filter is basically fixed, but there is a difference in how much.
In the air compressor system, we have a pre-filter and a post-filter, which are all determined by the difference in their filtration accuracy and the demand for compressed airHere's why:
First of all, we need to know the function of the pre-filter, which is used to remove part of the liquid water, lubricating oil and particulate matter with a diameter of more than 1 m. Whether it is an adsorption dryer or a refrigeration dryer, a pre-filter is a must. Otherwise, once the rust and other particles on the pipeline are carried out to the evaporator, it will greatly reduce the working efficiency of the refrigeration dryer and even damage the evaporator.
From the above explanation, we can see that the pre-filter can carry out preliminary filtration and purification treatment of compressed air, which can filter out a large amount of water, oil and larger particles, and at the same time play a protective role. Therefore, the air compressor pre-filter is a pretreatment of compressed air, preliminary filtration, and filtering out relatively large particles. If the compressed air containing a large number of impurities is not protected by the pre-filter, it will be directly treated by the post-filter, which may lead to the blockage or even damage of the gas-water separator and the drain valve.
In fact, the filter can also be divided according to its accuracy, and we have divided the general filter: pipeline filter, flange filter, stainless steel filter, medical filter, etc., which are also distinguished according to the accuracy and installation location (the environment used).
Extended reading: What is the function of compressed air precision filters.
When purchasing air compressors, they usually need to be equipped with compressed air precision filters. Compressed air precision filter is referred to as precision filter. So what help does the precision filter bring to the production?
In compressed air, there are generally dust, particles, and impurities. Dust and microorganisms will come into contact with food and pharmaceutical raw materials to contaminate products, which is more harmful to users. Water and dust can cause harm to the spraying process, resulting in pitting and fisheye.
In many cases, dust and water can also damage gas-using equipment and pneumatic components, such as placement machines, drilling machines, solenoid valves, etc.
A large proportion of these common hazards are due to contaminants in compressed air, but they have not received enough attention. Because damage to equipment is unavoidable, compressed air is not the only factor, but it is definitely a very large factor. If it is in the spraying industry, the compressed air that does not meet the standard will increase the defective rate by at least 5%, which is a headache when converted into expenses.
Therefore, we need to use a precision filter to filter out these dust and impurities. Purify compressed air. Bring greater efficiency to production.
