We can provide a variety of sizes and shapes of the venturi nozzle, coat steel sleeve, aluminum, nylon and other materials.

Divided Venturi nozzle structure contraction section, straight sections and diffusion segment of three parts, aerodynamic performance is superior to straight bore nozzle, vortex phenomenon is significantly improved or ceased to exist, the pressure loss is greatly reduced, at the same pressure conditions, increase exports to more than double the speed of the abrasive, work efficiency increased by 15% -40% compared to straight bore nozzle, abrasive consumption reduced by 20%.
Single inlet nozzle is a time into the wind. Double inlet is the second into the wind, before and after the two nozzles, there is space between the two, at around eight holes at intervals, in such a large and one small, the nozzle arrangement in a previous post, As the role of the high-speed air stream to produce a sufficiently large negative pressure, ambient air is drawn into the nozzle, the discharged air is greater than the compressed air into the nozzle outlet velocity abrasive increased again. In addition, double inlet jet produced sand lance end diameter larger than a single into a number of wind divergence surface abrasive stream into 30% larger than a single wind, higher cleaning efficiency.

Main application
widely used in Industrial production machines such as Sandblasting machines, hydraulic cutters, power plant boilers etc.
High temperature resistance, Abrasion-resistance, light unit weight, working life much longer than tradition material.
