Long Venturi Nozzles


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.

BR-VSA/B Series Boron carbide long Venturi nozzle

This series is widely used in sandblasting process with the requirements of long blasting distance, large cleaning area and huge impact.
