SN125-450 1/4″ (6.0mm) Silicon Carbide Double Venturi Blast nozzle

About the SN125-450 1/4″ (6.0mm) Silicon Carbide Double Venturi Blast nozzle

SN125-450 1/4″ (6.0mm) Silicon Carbide Double Venturi Blast nozzle

Lightweight Silicon 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.
