Bag filter is used as an efficient air pollution control system. Bag filter consists of a housing with multiple filter bags or cartridges mounted in it. The filter bags or cartridges are made of material suitable for operating temperatures and products being handled. The dust laden air or gas passes through the filter media and gets filtered. The mechanism to dislodge the dust adhering to the filters is either reverse pulse jet using compressed air/nitrogen or mechanical shaking using pneumatic cylinders. Fine particles having size as low as 0.1 microns can be filtered thus making it possible to achieve emission levels as low as below 10ppm.
