T125-850 1/2″ (12.7mm) Double Venturi Blast nozzle

About the T125-850 1/2″ (12.7mm) Double Venturi Blast nozzle

T125-850 1/2″ (12.7mm) Double Venturi Blast nozzle

Tungsten Carbide liner

Offers a major advantage when blasting the like of stainless steel

It has around 35% larger blast pattern than a standard long venturi with only a very slight loss in abrasive velocity.

Double venturi nozzles are used where a wider blasting pattern is needed. Air is drawn through the holes into a low pressure area, expanding the air flow to produce the wider blast pattern.

The Double Venturi Blast Nozzle produces a more even dispersion of abrasive throughout the larger blast pattern.
