Boron Carbide Lined Metal Jacketed Long Venturi Sandblast Nozzle
Boron Carbide nozzles are the longest lasting nozzles commercially available.
Boron Carbide costs more but will outlast tungsten carbide by 3 to 10 times.
Venturi Nozzle
Gas dynamic of venturi nozzle is better than straight-hole nozzle, the vortex is improved or ceased to exist, greatly reduced the pressure loss in the same pressure conditions. Abrasive exports increased to more than double the speed, efficiency than the straight-hole nozzle to increase 15% -40%, 20% lower abrasive consumption.

Advantages of our silicon carbide nozzle:
Venturi nozzles offer optimal removal rates due to a combination of high particle acceleration rates and low air consumption. Compared to standard straight blasting units, venturi nozzles are the best choice for large surface area preparation in painting and coating operations for the building and construction industries.
