Pocket Filter Making Machine Air Filter Bags Making Machine TC-7020

TheTC-7020 offers a multi-functional dual-mode system: slitting mode and rewinding mode, with options for single-output or dual-output production. It supports both rectangular right-angle filter bags and trapezoidal filter bags with adjustable angles—switchable via one button, with zero material loss.

The standard model produces filter bags up to 750mm width and 1800mm depth, meeting most mainstream requirements without mold replacement. For larger dimensions, customization is available. With precise ultrasonic welding, the finished bags feature clean, neat, and visually appealing cuts.

Slitting mode reaches 25–30 pcs/min, while rewinding mode reaches 20–25 m/min, depending on materials and bag size. Its automation, stability, and production capacity make it indispensable in the air purification industry.
