Requirement When The Air Passes Through The Drift Eliminator. Water Droplets Are Separated From The Air Drift At The Three Direction Change Points On The Drift Eliminator. For Cross flow Tower Applications, The Almost Vertical Water Conduits Provided by the CD-100 Drift Eliminator Remove the water droplets out of the drift eliminator area and return them back into the tower and does not allow any re-entry.Drift Eliminators, Made Out Of Rigid PVC, Are Designed To Remove Entrained Particles From Air Steam Efficiently, With Minimum Pressure Drop, Thereby Reducing The Fan Power
