Product characteristics
The four-proof punched felt bag is waterproof, oil-proof, anti-static and flame-proof, and also resists acids and alkalis. Developed from the three-proof cloth bag, it reduces combustion damage caused by sparks entering the dust collector.
It is suitable for locations with high moisture content and explosion-proof requirements, such as pulverized coal injection systems of blast furnaces in iron and steel plants, cement plants, starch plants and coal handling systems in power plants.
