729 filter cloth has high strength, low elongation, resistance to strong acid, weak alkali, long service life, good air permeability, high dust collection rate, easy to remove dust, dust removal efficiency up to 98.99%.
208 filter cloth with good ventilation performance, high dust removal efficiency, and a certain degree of acid, alkali and heat resistance, using a multilateral brushing, increased fabric thickness, elasticity, dust removal rate of up to 99.9%.
729 dust filter bag is made of polyester staple fiber as raw material woven filter cloth, widely used in cement mill ball mill grinding dust, with high strength, low elongation, resistant to acid, weak alkali, the service life is generally glass 4-6 times that of the fiber fabric, good air permeability, high dust collection rate, capacity clearing ash, dust removal efficiency over 98.99%. 729 filter cloth products have high dust-removing efficiency, low initial resistance, good ventilation and ventilation performance, and easy to clean without knotting, seamless, no cracking, high strength, wear resistance, heat resistance, acid resistance, alkali resistance and other excellent performance. 729 Filter cloth is developed based on chemical, smelting, grain processing and other industries. It can meet the dust collection process requirements of the industry and effectively improve the recycling efficiency.
