Bag filters are used for very high collection efficiency, even for very small particulates, can be operated under different dust conditions and flow volumes, energy conservation occurs, no risk of causing water and soil pollution.
In the bag filter, a flow of dirty gas particles will enter into several filter loops (also called bags or cloth bags) which are lined up in parallel, and leave dust on the filter. The flow of dust and gas in the filter bag can pass through the fabric in all directions.
