Fertilization and Plant Protection Trailed Type Turbo Atomiser Turbofan on the machine provides compressed air around it with its propeller which takes its movement from the tractor tail axle. As standard, the movement is transferred to the turbo fan by a belt-pulley mechanism. With the separator on the fan, the propeller is prevented from rotating by taking it empty when desired. The air flow rate can be controlled by adjusting the direction of the moving fan of the fan. By adjusting the angle and direction of the nozzles on the fan or by changing the plaques, the throw distance and the amount of medication can be adjusted. By using the distributor valves on the regulator, medication can be shot in right, left or both directions. The turbo fan offers an average throw distance.
