These pockets are embroidered using internal fales stitches or ultra-sonic welding processes with internal spacers to maintain uniform airflow channels for even dust loading and longer filter life. The evenly balanced pocket design allows full media inflation without crowding or restricting airflow to ensure optimum and equitable media utilization which results in 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. This design prevents air bypass by eliminating metal contact points between components. Plastic frame construction comes as an option.
