The Nebbiasecca device is designed for spraying water-based insecticide and disinfectant solutions. Atomising is carried out by the atomising unit at the top of the removable rod, which is powered by compressed air. The tank (photo 3) containing the solution is pressurised by compressed air with a maximum pressure of 0.5-1 bar: This causes the solution to flow out towards the atomising unit. The solution exiting the nozzles is atomised by means of compressed air, set at a pressure of 3-4 bar.
