A bag filter bag, also known as filter bag or dust collector bag, is an essential component used in bag filter systems for air or liquid filtration. It is typically made of high-quality filter media, such as polyester, polypropylene, or nylon, and designed with a cylindrical shape.
The bag filter bag is engineered to effectively capture and retain suspended solids, dust particles, or other contaminants present in the fluid or air stream. It operates on the principle of filtration, where the fluid or gas passes through the fabric of the bag, while the particles are trapped inside the bag.
These bags are available in various sizes and configurations to suit specific filtration requirements. They are commonly used in industrial applications, including power plants, chemical plants, pharmaceutical manufacturing, food processing, and many others.

The filter material forms a three-dimensional, highly fluffy three-dimensional depth, tortuous filter layer, which is characterized by loose fiber tissue, increasing the capacity of impurities, the fiber material is a compound interception mode, effectively remove solid and soft particles, that is, the larger particle impurities are intercepted on the surface of the fiber, while the fine particles are captured in the deep layer of the filter material, to ensure that the use of the process will not be caused The pressure increases and the damage, so it has a high filtration efficiency, in addition to the high temperature surface heat treatment, that is, the application of instantaneous sintering technology/calenderization, can effectively prevent the fiber from being lost by the liquid high-speed impact during filtration, not only to ensure that there is no fiber from causing filtrate pollution, but also to avoid the traditional roller treatment caused by excessive blockage of the filter hole and shorten the life of the filter bag, while the pressure difference is small and does not affect Flow rate.
