Instructions For Using And Replacing The Air Filter Media

The primary - efficiency Air Filter Media and the medium - efficiency Air Filter Material use metal materials as the frame to give people a sense of Chinese characteristics. The choice of green material is theoretically the same as that of the disposable paper frame. The main reason for making the metal frame is that it is durable and cost - effective. Due to the use of metal frame, every time the filter life is reached, only the inner filter element needs to be replaced, thus saving costs.

It is one of the first filter manufacturers in the same industry in China to pass ISO14001 and ISO9001 at the same time. It has the world's best air filter production clean workshop, high - efficiency filter production line and advanced testing equipment. It is a world - renowned professional in purification equipment and air filter products. One of the research and development, design and production bases, the primary efficiency filter, the medium efficiency filter, the high efficiency filter and the production process have many national patents. It has the support of leading enterprise customers in various fields around the world. It continuously improves various performance parameters of the air filter, reduces the overall operating cost and maintenance cost, and enables users to obtain products with better cost performance.

Bag filter is essential for general ventilation and air conditioning system. It is the main force of filtration. The bag type is mainly to meet the requirements of large air volume and low resistance. Strictly speaking, the front end of the bag filter also has a layer of pre - filtering device, which generally uses a disposable paper frame or metal frame plate filter. However, some domestic users do not replace the front - end paper frame filter after reaching its lifespan, and directly use the bag filter for priority filtration. As a result, the use environment of the bag filter is harsh, the service life is shortened, and the design requirements of the manufacturer cannot be met. This situation should be avoided as much as possible. Although the cost of adding a pre - filter increase, the replacement cycle of the bag filter can be extended. In the long run, total maintenance costs are reduced.

HEPA Filter Media with partition is for different particle diameters, and the efficiency of the high - efficiency filter can reach more than 99.999. Some people always associate the efficiency level of the filter with the level of the clean room. It seems that how many ultra - efficient filters of 9 can be used to achieve a cleanliness level of 100 or even 10. Actually this is a wrong notion. The high - efficiency filter is the core of the system, but it is not the only condition to ensure cleanliness. The efficiency of the Hepa Filter Material is only one of the necessary conditions, and it is also a condition that is easy to achieve. In order to achieve the corresponding level of clean room, there should be many necessary conditions, such as wind speed, number of air changes, door and window sealing, clean room control of personnel entering and leaving, and many other aspects. Only when all of these aspects meet the standards can the clean room cleanliness requirements be guaranteed. Filter manufacturers are only responsible for filter compliance. No one or manufacturer dares to say: how many grades you can achieve with my filter!

Since the hepa filter material without partition is generally used as the filtration end, the requirements for the high - efficiency filter are also strict, and the factory needs to be tested one by one. The high - efficiency filter as the end is the key stage of the filters of all levels and requires additional "observation". To prolong the service life of the hepa filter media, the fundamental way is to block the dust in the pre - filter. Replacing the pre-filter generally does not require production stoppage or debugging, so experienced owners will put their attention and money on the pre - filter. For Class 10000 and Class 100000 clean workshops. F8 filter ( 95 % colorimetric method ) can be selected for pre - filtration, so that the service life of the terminal high - efficiency filter can generally reach five years. In foreign projects and new domestic projects, F8 filter is a common pre - filter in non - uniform flow clean rooms. For chip factory 100, 10 or other clean workshops with more experience, the common efficiency level of pre - filter is H10 ( MPPS 85% ), and many new projects choose HEPA. In the past clean room air - conditioning system design in China, the common configuration of the filter is: coarse - efficiency → medium - efficiency → high - efficiency. At that time, the service life of the high - efficiency filter was only 1 - 3 years, and the difference was only a few months. It can be seen that the efficiency of the pre - filter determines the service life of the end filter.

Today, we mainly introduce the resistance of the primary filter, the medium - efficiency filter, the high - efficiency filter and the importance of its use. After that, it is recommended that you regularly check the air volume and other environmental parameters in the clean area every year.
