Expanded glass fiber filter cloth is made from textured glass yarn. Due to its bulky character, it has high covering capacity and good air permeability, thus provide higher filtration efficiency, lower filtration resistance and improved dust-separation efficiency up to 99.5%. It is suitable for dust separators with high-speed reverse air or pressure drop reverse air system. It is mainly used for cement and carbon black industries.
