High temperature resistant dust bag can withstand high temperature environment up to 260 ℃. The high temperature tolerance of this material makes it an essential filter material for many high temperature industrial processes. For example, high temperature flue gas dust removal in steel, cement, glass and other industries. Our filter bags are suitable for flue gas filtration in chemical, steel, metallurgy, carbon black, power generation, cement, water treatment, waste incineration and other industrial furnaces.



  • Excellent Filtration Efficiency

The high temperature resistant dust bag has excellent filtration efficiency and can effectively filter out tiny particles. The filtration efficiency of this material can reach more than 99.9%, which can effectively protect the environment and human health

  • Corrosion resistance

The high temperature resistant dust bag has good corrosion resistance and can withstand the erosion of corrosive substances such as acid and alkali.

  • Long life

The high temperature resistant dust bag has a long life and can be used for a long time in harsh environments such as high temperature and high pressure.
