Fresh Air Primary Filter Easy Installation Complete Efficiency Classification
Fresh Air Primary Filter Easy Installation Complete Efficiency ClassificationPrimary effect filters are generally classified into eight types, namely: G1, G2, G3, G4. GN (nylon mesh filters), GH (metal mesh filters), GC (activated carbon filters), GT (high-temperature roughing filters), the process of the plate, folding type, bag style three styles, the outer frame material has a paper frame, aluminum frames, galvanized iron frame. At present, there are also stainless steel frames, borderless designs, and so on.For fresh air primary filter installation, the general frame adopts a sturdy plate aluminum alloy frame, the wind surface with diamond-shaped net to ensure that the filter is not deformed or damaged in the poor working environment, the lightweight plate structure, the filter material adopts a good polyester synthetic fibers, which can be cleaned and reused many times, with long service life and economical and practical, fluffy and gradually dense fiber structure ensures a higher rate of dust aggregation and a larger amount of dust capacity to effectively extend its back-end intermediate effect filter, which is also used in the filter. The fluffy and dense fiber structure ensures a high dust collection rate and large dust holding capacity, which effectively prolongs the service life of the back-end intermediate filter. In the new air system, primary, medium, and high-efficiency filters are generally not used alone, but two or three with the use of the assembly of two or more layers of filters in the new air system, to achieve a bad air filtration phenomenon, the primary filter resistance has been over the rated primary resistance of 60Pa, or run the primary resistance of 3-6 months, over the standard on the replacement of the coarse filter every week on the filter, the medium filter, back to the mouth of the device to clean 1 time. |
