It is the most efficient types of ring packing for large scale superior characteristic derive from the slotted wall and the internal projecting tongues, which give this higher capacity or lower pressure drop, also higher contact efficiency arising from the better disposition. And better wetting of the surface Migration of liquid forward of the vessel wall is also reduced. The free gas space is much this same as for plain rings

Polypropylene Plastic intalox saddles are a highly effective packing for use in most fume removal applications. A typical Scrubbing is shown here in schematic form. The polluted air or gas steam is drawn through a bed of wetted plastic intalox saddles which provides very large surface area contact promoting rapid absorption of pollutants into the liquid stream. Contaminant removal efficiency of 99% are possible at relatively low liquid flow rates. Size available 1”, 1.5”, 2”, 3”, and 3.5” dia
