Venturi Model
The VENTURI MODEL provides a variety of advantages and solution for sensitive ground drilling:
- The flushing air does not hit directly to the bottom of the borehole.
- Minimal air leakage into the formation to eliminate enlarging borehole.
- The reverse flushing causes a vacuum effect to remove the cuttings.
- Face groove designed by CAE simulation and analysis for more efficient flushing.
- Standard and Big Bore systems are available.
