It has a high dust removal efficiency, generally above 99%, and the dust concentration in the gas at the outlet of the dust collector is within tens of mg/m ³. It has a relatively high classification efficiency for fine dust with sub-micron particle size. The range of air volume processed is wide, from just a few cubic meters per minute for small ones to tens of thousands of cubic meters per minute for large ones, reducing the emission of air pollutants. When high-temperature resistant filter materials such as glass fiber, polytetrafluoroethylene and P84 are used, it can operate under high-temperature conditions above 200℃. It is used for dust treatment of powder and granular materials in industries such as building materials, grain, tobacco, pharmaceuticals, chemicals, and steel.
