The correct selection method of primary effect filter
The correct selection method of primary effect filterThe area of the filter material in the air filter is called the "filter area", except for a small number of low-efficiency filters, the filter area of an air filter is usually a few times the windward side of the filter, dozens of times, and sometimes up to a hundred times, the dust that is captured will be concentrated on the windward side of the filter material. The larger the filter area in the air filter, the more dust it can hold, and the longer the service life of the filter.According to many years of industry experience of primary filter manufacturers, for the same structure, the same filter material air filter, when the final resistance is determined, the filtration area will increase by 50%, the service life of the filter will be extended by 70 to 80%, doubled, the service life of the filter will be about three times of the original. Filter material, the price of the filter will also increase accordingly, but the extension of the filter life of the magnitude of the air filter price will certainly be higher than the magnitude of the price increase, in addition, the filter area increases after the initial resistance will be reduced, the air conditioning system's energy costs will be more or less down some. The size of the filter area does not have much effect on the efficiency of the air filter. However, for users, the choice of air filters with large filter areas will be more cost-effective than air filters with small filter areas. |
