Hot-melt Pocket Filter

The hot-melt pocket/bag filter is characterized by the use of hot-melt adhesive, which is a thermoplastic material, to secure the filter media in place within the filter frame.
The hot-melt adhesive is applied as a liquid and solidifies upon cooling, creating a strong bond between the filter media and the frame, which ensures that the filter media remains securely in position, even under high airflow conditions.
This bag filter media consists of a graduated multi-layer structure with each layer having a different density or filtration capability. Larger particles are captured near the surface, while smaller particles are caught in the denser, inner layers.


  • Grade: G3, G4, M5, M6, F7, F8, F9;
  • Frame options: Stainless steel, aluminum alloy, or ABS
  • Graduated density structure enhances efficiency
  • Secure seal at the connection ensures no air bypass or leaks under a high airflow rate
  • 3 small pockets in each row divert and equalize the airflow, keeping bags in shape for  better performance and lower energy consumption
  • Long filter service life and high dust-holding capacity
