What is the process of bag air filters?

What processes need to be confirmed for bag air filters? Depending on the structure, filters are able to be categorized into several types, and bag filters are one of them.
       So what are the processes that need to be confirmed when purchasing bag filters?

Filtration efficiency: this point is mainly for the medium-effect bag filter. Many friends are aware of the medium-effect filters are usually a variety of different colors, which is not only for aesthetic purposes, but also through the bag color to show the filtration efficiency of this filter. In general, the white filter represents the filtration efficiency of F5, that is, 40-60%; green filter represents the filtration efficiency of F6, that is, 60-80%; pink filter represents the filtration efficiency of F7, that is, 80-90%; yellow filter represents the filtration efficiency of F8, that is, 90-95%; yellow-white filter represents the filtration efficiency of F9, that is, 95-95%. efficiency is F9, i.e. 95-98%. Size According to the size of the air purification system, the size of the bag filter required is also different.
        Broadly speaking, it includes width*length*bag depth*thickness, and specifically, it can also include the number of bags, rated air volume, etc. If you need some special dimensions or specifications, you can also propose them to the bag filter manufacturer to make according to the demand. If you need some special dimensions or specifications can also be proposed, so that the bag filter manufacturer according to the needs of production. Frame Material Most of the frames of bag filters are metal frames, on the basis of which there may be a variety of different materials, including double U-shaped aluminum frames, galvanized iron frames and so on.
       The bag is held open by a support grill that locks into the U-frame, and the adjacent grill holds the bag in place with a special knot lock that prevents the bag from falling out of place during handling of the filter. All metal edges of the filter are rolled inward to prevent scratches during filter installation and replacement. Bag Material Depending on the filter media in the bag filter, it can be divided into different functions. For example, the filter bag of bag type activated carbon filter is made of highly adsorbent activated carbon fiber and filter cotton, with strong surface adsorption capacity and low resistance, which can effectively control the odor and organic pollutants in the air, and it is very suitable to be used in paint spraying workshop and other places with heavy odor.
       If there are no special needs, bag filters are usually made of high quality fluffy synthetic fibers and have more than one layer. The first layer is generally used to filter the larger particles in the air, and then the finer second layer is mainly used for the stability of the Tsangjiang filter and to filter the smaller particles. This design reduces the filter resistance, increases the dust holding capacity and extends the service life.
         If there is a specific need for some of these processes, you can also ask the manufacturer to find the corresponding product or customize it.
