Worn nozzles cost money! A venturi blast nozzle interior has a shape and length specifically designed for it’s orifice size. This is to ensure optimum performance and efficiency. A worn nozzle is more costly to use for two reasons…
- A bigger orifice requires more compressed air to maintain a desired pressure.
- The even spread of abrasive across the blast pattern deteriorates as the blast nozzles wears.
To check the amount of wear in your nozzle…
- Mark the rear of the engraved section of the gauge with a crayon.
- Insert the gauge into the rear of the nozzle (threaded end).
- Orifice size can be determined by observing the highest orifice size marking from which the crayon has been removed.
