The World’s Quietest Blast Nozzles
• 45% Less Thrust!
As one of the largest powder coating companies in central NSW, this client’s high standard powder coating finish ensures that fabricated steel products can withstand years of outdoor exposure and usage. They offer abrasive blasting, zinc powder priming and powder coating services.
With the launch of BlastOne’s new SnakeBite nozzle, a large powder coating company wanted to test its efficiency. Together, we hosted a trial comparing a #7 BlastOne Ultra Tuff nozzle to the new SnakeBite Strike #10 nozzle. The trials focused on production rate and noise level. Additionally, abrasive consumption rates were also calculated to showcase overall cost.
BlastOne and the powder coating company conducted a study to determine whether the SnakeBite would reduce blasting noise without reducing productivity. Blasting a bin with large sides, no coating, here is how the #7 Ultra Tuff compared to the SnakeBite Strike:
|Nozzle||Nozzle Pressure||Test Area||Blast Time||Blasting Speed||Sound Reading|
|#7 Ultra Tuff*||115 psi||1 m2||65 s||55 m2/hr||106 dBA|
|SnakeBite Strike||102 psi||1 m2||43 s||83 m2/hr||98 dBA|
|Nozzle||#7 Ultra Tuff*||SnakeBite Strike|
|Nozzle Pressure||115 psi||102 psi|
|Test Area||1 m2||1 m2|
|Blast Time||65 s||43 s|
Unfortunately, at the time, no sound readings were taken from further away, outside of the blast room. The difference in noise is even more obvious when you move further away.
Using the True Cost Abrasive Blasting Formula, we calculated the amount of abrasive used per square metre by each nozzle.
|Nozzle||Consumption Rate||Abrasive Purchase Cost Delivered||Abrasive Disposal Cost||Labor and Equipment Cost||Production Rate||Blasting Costs|
|#7 Ultra Tuff||.48 t/hr||$695/t||$50/t||$150/hr||55 m2/hr||$9.23 per m2|
|SnakeBite Strike||.48 t/hr||$695/t||$50/t||$150/hr||88 m2/hr||$5.77 per m2|
|Nozzle||#7 Ultra Tuff||SnakeBite Strike|
|Consumption Rate||.48 t/hr||.48 t/hr|
|Abrasive Purchase Cost||$695/t||$695/t|
|Abrasive Disposal Cost||$50/t||$50/t|
|Labor and Equipment Cost||
$9.23 per m2
$5.77 per m2
Our estimates show that the SnakeBite Strike is not only quieter than the #7 Ultra but it’s high productivity results in 37% less abrasive used per square metre. Over 1000 square metres, that is $3,460 back in your pocket! Almost covering the cost of the initial investment.
Blasting speed increased by 51% which is more than a day’s extra blasting each week.
Sound level was almost halved, which improved the surrounding environment for nearby workers and prevented disrupting workflows. While the SnakeBite Strike was in action, the noise was significantly reduced and a normal conversation (80dBA) could happen during blasting.
The SnakeBite Strike achieves over 50% more production than high performance #8 nozzles. The only #10 nozzle in the market that can be used for hand-held blasting for extended periods of time.
The SnakeBite Strike reduces noise generated by up to 16 dBA – that’s equivalent to up to 75% quieter than standard nozzles, and the typical high pitched screech is now gone.
Reduce the risk of operator and bystander hearing related injuries and increase your ability to comply with workplace noise regulations.
SnakeBite Strike is the highest productivity hand-held blast nozzle on the market. Reduce your overall blasting time on projects while increasing your profits.
The unique design of nozzle and silencer reduces operator fatigue by up to 45%. Operators can better maneuver the nozzle and will be less fatigued over the shift.
Until now, when companies needed a high production nozzle to blast acres of steel – they relied on a #8 hyper nozzle. This was the largest nozzle a man could handle for 4-6 hours on any given day.
Some contractors don’t even realize #10 nozzles are an option… and that’s because a #10 exerts far too much thrust for practical, daily blasting. That is… Until now.
The same design technology that reduces both the noise and thrust on our SnakeBite XQ… also makes the Snakebite Strike – the world’s most effortless #10 blast nozzle.
The only caveat is you need to have enough air. Your compressor needs to supply at least 750 cfm per Strike nozzle.
But 54%? Really?
Well to start, here are some simple measurements comparing a single pass of a Snakebite #10 with various other nozzles, including a #8 Hyper.
|Nozzle Size||Single Pass Pattern Height Through Paint||Single Pass Pattern Height Through Flash Rust|
|#6||1.5″ / 3.8cm||2″ / 5.08cm|
|#7||1.75″ / 4.45cm||2.25″ / 5.715cm|
|#8 Hyper||2″ / 5.08cm||2.5″ / 6.35cm|
|#10||2.25″ / 5.715cm||3.0-3.25″ / 7.62-8.255cm|
|#10 Snakebite Strike||2.5″ / 6.35cm||3.25-3.5″ / 8.255-8.89cm|
Productivity of the Flex is comparable with standard nozzles (same size, pressure, media) and the XQ is up to 25% more productive than standard nozzles of the same size. The reduced nozzle kick-back thrust – up to 45% – can actually increase productivity by reducing operator fatigue and enabling a high rate of productivity to continue throughout the shift…. and the #10 Strike (due to the larger orifice size) can increase hand-held blasting productivity up to 54%.
Adjusting these factors will have an effect on dB reduction.
