Factors Affecting the Life of High Efficiency Filter

Customerhigh efficiency filterThere are three main reasons for the complaint of short service life. First, the vibration area of the filter material is too small or the volume of the unit chamber is too small. Second, the filtration efficiency of the pre-filter is low. Finally, the user's expectation of the service life of the filter is too high. In addition, there are no other reasons. Let me introduce the influencing factors of the service life of the high-efficiency filter.
The first reason is that the use of high-efficiency filters with large filtration areas can extend the service life of the filters, which should be considered in the initial design of the system. In many projects, users request to minimize the space occupied by the air conditioner, or provide cheap filters with a small filter area to maximize profits. When the project is accepted, the filter can meet the requirements of air purification, but the service life of the filter is short and the filtration efficiency of the pre-filter is low.
In this way, the efficiency of the front filter can be adjusted and the service life of the end filter can be extended. According to the test data, the terminal filter is F7. When using G4 pre-filter, the service life of the end filter is 3 months. After using the pre-f5 filter, the service life of the F7 filter can be extended to half a year. In a clean room, the value of the final efficiency may not be high, but the risk and indirect cost of replacing the filter will be very high. There is no need to replace the pre-filter. Experienced owners will pay attention to the pre-filter.
And according to experience, the 10000 level, 100000 level clean workshop pre-filter selection F8 filter.high efficiency filterThe service life of up to 5 years, in general, the current domestic common filter configuration may be only 1-3 years, so it gives some suggestions for filter selection.
First of all, we should choose a filter with high enough efficiency, and secondly, we should also choose a filter with a large filter area. High efficiency filters must be tested one by one. Select the filter with small initial resistance under the same air volume. A filter with a conventional size is selected to stop the movement of dust molecules in the air without being affected by molecular movement.
And in this experiment, when entering the filter medium chamber, the medium may collide, and when it collides with the medium, it will leave smaller dust, form larger particles, and make the barrier sink. The concentration of dust particles in the air is relatively stable. This is why we should choose a good high efficiency filter principle.
