The use of air filters 1, No matter what grade filters all have their uses, are required within the proper scope of use, if used properly, they not only will not play the role of filtering, but also may have the opposite effect. 2, First of all we look for coarse filter, which is used as a pre-filter to use, and its role is to filter larger particles of pollution, protection and many other subsequent equipment to function properly, the device can not pay attention to this as filter terminal. 3, In effect filter is usually set at a positive pressure section of the system, its primary role is to protect the subsequent efficient filters, etc., can effectively remove small contamination particles ≥1.0μm can not not do as a pre-filter terminal filter device. 4, The final say is highly effective filter, which is the terminal of the entire purification system filtration equipment, capable of filtering contaminated particles 0.1μm and is generally clean room must filter. The replacement of the air filter 1, No matter what type of filter After a period of operation, when it reaches the end of the resistance division Hz resistance would need to be replaced, otherwise its performance will be greatly reduced, can not play its due role, even It will affect the normal operation of the entire system. 2, For coarse, medium efficiency filters, the use of some one-time, after some of them are able to continue to use clean, but rough after cleaning, in effect filter resistance is much larger than the resistance early. 3, And for efficient and ultra-high efficiency filters are one-time use of the device after reaching the final resistance value should be promptly replaced.
