So
• longer bag service life
• increase the air volume of existing dust collectors to increase production capacity
• lower emission
• reduce energy consuption
• reduce operation cost
• reduce pressure drop
• lower pulse jet pressure and frequence
• small bag house and building area
• lower the filter velocity
