Short service life is mainly caused by three reasons:
1, the filter material area of the air filter is too small or unit capacity is too small;
2, the user of the life expectancy of the air filter is too high.
3, the low efficiency of pre filter air filter;
In view of the above reasons, the use of large filter area filter can extend the life of the system, the system should be designed to take into account the initial design. More projects, the user requires as much as possible to reduce the space occupied by air conditioning, or suppliers in order to achieve maximum profit, the use of a small filter area of cheap air filter. Acceptance of the project, the air filter can meet the requirements of air purification, but the life of the air filter is relatively short.
Pre filter efficiency is low, you can adjust the efficiency of the pre filter, you can extend the life of the end of the air filter. According to the test data: at the end of the air filter is F7, use the G4 pre filter air filter service life is 3 months, with the pre F5 air filter, F7 air filter service life can be extended to the first half of the year. In the clean room, at the end of May, value is not high, but the risk of air filter replacement and indirect costs will be very high, for the pre filter is not discontinued, experienced owners will focus on pre filter.
