Cascade ring, a packing media designed to give enhanced capacity, increased efficiency and mechanical strength over the older style Pall ring packing. The height/diameter ratio of the packing is 0.5 which is only half that of the known Pall Ring. Because of this aspect ratio, when this packing is installed in a tower it tends to orient in a more structured way such that its inner surface could be more efficient. All these features, therefore, decrease its pressure drop and increase the mass transfer efficiency.

They are available in variable sizes such as (mm): 25,50,76
