Long venturi nozzle has the structure with the converging section, straight section and diffuser

section. Compared with the straight hole nozzle, it has better function of gas dynamics, strong

improvement in vortex, less pressure loss. Under same pressure, the exit velocity of sandblasting

meterials almost doubles as the speed of voice, resulting in higher momentum of the abrasives,

increased impact energy and added effectiveness of cleaning

Approximate Nozzle Service Life in Hours:
