Units with rotary sprinklers are designed to minimize carry over by judicious choice of air flow velocities. The air distribution is aided by using a centrally located rotating eliminator section to avoid high velocity areas. Further, the pipes are covered by zerofoil section eliminators which helps arrest small droplets from escaping and for evenly distributing the sprinkled water. For the towers using stationary sprinkler nozzles, a full width eliminator covering the full cross section is used. The shape of the eliminator is chosen to minimize pressure loss of air and to trap the maximum amount of entrained droplets.
