SANDBLASTING

SANDBLAST

Pressurized water propelled through a nozzle circulates inside the jet at high speed, causing a vacuum due to the Venturi effect and creating suction at the rear of the accessory. The suction must be connected by hose to the container with sand or the desired additive.
Cleaning with pressurized sand-water jet is more powerful than using only pressurized water. The sand abrades the surface to be cleaned. If you want to control the impact of the sand, you can use sands of different grain sizes and vary the working pressure; additionally, pressurized water prevents the formation of dust harmful to people and the environment.

It is used to remove paint, oxides and very adherent residues from surfaces that would be very expensive to remove with only pressurized water.
