Non-Ferrous Metals

Dust Filter Bags for Non-Ferrous Metals

Our dust filter bags are engineered to withstand the extreme demands of the non-ferrous metals industry—including high-temperature fumes, acidic gases, and fine particulate emissions generated during smelting, sintering, and roasting operations.

  • High Temperature Resistance 
    Continuous operation up to 260°C (500°F), peak tolerance over 300°C

  • Superior Chemical Resistance
    Ideal for acid-laden exhaust (SO₂, HCl, HF)

  • Fine Dust Capture 
    Filtration efficiency reaches <5mg/Nm³ with membrane or surface treatment

  • Long Service Life
    Durable needle-punched felts and PTFE membranes extend change-out cycles

  • Customization Available
    Supports various sizes, bag head designs (snap band, ring, flange)
