  • Recirculation jacket filter system
    Patent number: 7150778
    Abstract: The present invention is a system and method for improving the useful life of sorbent beds, such as activated carbon filter beds. It is known that breakthrough in carbon filter beds first occurs at the low gas velocity regions of the filter bed, i.e., at the filter's edges. A recirculation jacket filter system diverts already filtered air from the downstream side of the filter bed toward the peripheral region of the upstream side of the filter bed so that contaminants near the filter's edges are reduced and filter life is improved.
