Air filter bag

polyesterfiberpleated

The dust bag is the heart of the bag dust collector during operation. Usually, a cylindrical pulse filter bag is suspended vertically in the dust collector. Some large particles of dust are separated by inertia and fall directly into the ash hopper. Dust-containing gas enters the filter bag filter area of the box. Most of the dust is captured on the outer surface of the filter bag, and clean gas enters the inside of the filter bag through the filter material , and then discharged from the air outlet. The cage inside the filter bag is used to support the filter bag and prevent the filter bag from collapsing. At the same time, it helps to remove and redistribute the dust cake. Specifications The diameter of the filter bag is 115-200mm, length is 2000 - 9000mm, the specifications of the commonly used filter bag is 120 - 160 mm diameter, 2000 ~ 6000mm length.
