Medium alkali expanded glass fiber filter

Medium alkali expanded glass fiber cloth is a new type of high-efficiency filter material developed on the basis of continuous medium alkali glass fiber filter cloth. It differs from continuous medium alkali glass fiber cloth in that its weft yarn is expanded by medium alkali glass fiber. The yarn composition, because of the fluffy yarn, high coverage and good gas permeability, can improve the filtration efficiency, reduce the filtration resistance, and make it suitable for high air volume and high concentration dust collection.
