What is Rigid Pocket Filter Material?

Rigid pocket filter material is a kind of bag filter welded by using high-frequency technology. It uses special high-efficiency filtration materials, such as non-woven fabrics and filter paper, which are heated and fused by high frequency to make bags with specific shapes and sizes. These bags are installed in air filtration equipment to filter particles in the air and serve to filter the air.

Application of Ultrasonic Welding Technology

The core advantage of the ultrasonic bag air filter is that the edge of the filter bag is welded by ultrasonic hot melt, which is not only efficient and clean but also avoids the leakage problem that may be caused by traditional sewing or needle and thread welding. For example, the bag edge of the bag medium effect filter is fused by ultrasonic, ensuring excellent air tightness and bonding strength, preventing air leakage or rupture. In addition, ultrasonic welding technology is also widely used in the production of early effect and high efficiency air filters
