Currently, filters are widely classified, and self cleaning filter are more popular. It is extremely versatile, inexpensive, and more importantly compact and has applications in many environments. Common applications for self cleaning filter are central air conditioning, as well as a clean return air system and a large air compressor pre-filtration system. It mainly shoulders the role of primary filtration, so the structure is relatively simple.
At present, there are many varieties, except for the common G1, G2, and G3, as well as nylon mesh filters or activated carbon filters, which are replaced by GN and GC, respectively. The structure of the self cleaning filter is very characteristic. From the appearance, it uses a waterproof board, the overall shape is very strong, the placed filter material is already folded, and the diagonal design is particularly important. The reason for this treatment is to increase the filtration area and ensure the filtration effect.
After the above treatment, the outer frame position will be close to the inner filter material, and the combination of the two is very good. It uses a special glue, and there is no air leakage at all, even if it is facing too high wind resistance pressure. There will be no problems. We need to maintain it according to the frequency of the use environment. The replacement period is 1 to 6 months, and it can be measured by the action of the dust particle counter.
