High Capacity and Low Pressure Drop,Low aspect ratio increases capacity and reduces pressure drop. The preferred vertical orientation of the packing axes allows free gas flow through the packed bed; Low pressure drop and high capacity allows smaller column diameter and blower sizes in new installations; Multiple sizes provide ability to optimize capacity and efficiency based on application requirements ©~ Fouling Resistant: Open structure and preferred vertical axis orientation inhibits fouling by allowing solids to be more easily flushed through the bed by the liquid ©~ High Mechanical Strength: Ring and spoke construction and preferred vertical orientation provide high mechanical strength, which allows use in deep beds
