It is composed of 4 references depending on their capacity and use: Evolution 12 and 16, Evolution 16 and 20 Agro. They are suitable for work from urban gardens to intensive crops – industrial and extensive – by covering the needs of amateurs and professionals alike.

Below, we will detail some more significant characteristics of the sprayers.

Evolution 12 and 16, Evolution 16 Agro and 20 Agro
