G-Bag provides extended surface filtration through media formed into individual dust holding pockets. These pockets are created by internal span stitches to maintain uniform airflow channels for even dust loading and long filter life. The perfectly balanced pocket design allows full pocket inflation without crowding or restricting airflow to ensure optimum media utilization and thereby offering long service life. Each pocket is bonded and sealed to its own "J" channel support frame which is fastened to a heavy duty corrosion resistant steel frame with soft edges to avoid damage to the filter media.
