PNEUS is a professional airless gun, manual or automatic control, for spraying the internal surface of pipes. This gun is able to spray the inside of tubes having a minimum diameter of 250 mm up to a maximum of 700 mm. The spraying of the material takes place via airless system (hydraulic pressure) thanks to a pneumatic swivel head rotating at 360 ° equipped with an airless spray nozzle. It is possible to adjust, according to the need of spraying, the speed of rotation (10 to 100 RPM).
