As height of cascade rings is 1/2~1/3 lower than Pall rings, so average route by which air flowing around the external wall is greatly shortened, so the pressure drop when air pass through filling layer is reduced.

Ceramic cascade ring

The Height/Diameter ratio of ceramic cascade ring is 1:2, added cone-shaped flanging at one end, so it reduced the resistance when air pass through bed layer, and increased voidage. The strength of this kind of filler is very high. Due to its special structure, air distributing in it was average, so it increased air touch area and improved transfer efficiency.
