Specialized Cartridge-based Molecular Control (GC Cartridges) Four filter cartridges hold up to 12 lbs. of granular and/or pellet-shaped gas phase control media. The cylindrical shape of these cartridges allows for optimum contact, which ensure high removal efficiencies. The large surface area of the cartridges enables high airflow rates.
