Factors Affecting Efficiency of Bag Filters Four important factors affect the efficiency of the system. These include the Filter Ratios - This is ratio of carrier gas volume to gross filter area per minute flow of gas. Filter Media - Media must have sufficient temperature, chemical and abrasion resistance. Bleeding - It refers to penetration of the fabric by finer particles.
Temperature - Most filters have an upper temperature limit of 290 Degrees. In addition, certain gases like sulphur dioxide form acids at certain temperatures in the filter.
