Additional information on the Blast Ninja family of nozzles

Blast Ninja is a next-generation abrasive blasting nozzle that significantly reduces noise exposure at the source.

The Blast Ninja abrasive blasting nozzle is a revolutionary design, engineered to reduce blasting noise levels by up to 17dB.  The proprietary technology leverages years of aero-acoustic research conducted for jet engine noise reduction and was created in partnership with the U.S. Department of Defense.

Blast Ninja’s design reduces nozzle air exit velocity while maintaining particle velocity – reducing noise at the source while maintaining blasting coverage. Oceanit has performed many rounds of lab analysis, field trials, and rigorous testing in various blasting environments to arrive at the final Blast Ninja product.

OSHA Compliance

OSHA has implemented noise exposure limits for the worker’s health and safety. Exposure to high levels of noise can lead to: hearing loss, tinnitus (ringing in the ear), stress, anxiety, high blood pressure, gastrointestinal problems, and chronic fatigue.

At 115dB, the average volume of abrasive blasting operations, OSHA regulations allow for just 15 minutes of exposure. Down time creates excess costs associated with an idle asset. Per OSHA requirements, better hearing protection does not reduce worker noise exposure. Only by reducing sound at its source will a worker experience non-hazardous noise.

Blast Ninja meets OSHA’s noise standard compliance (29 CFR 1910.95) of four hours of exposure, meaning that operators are protected, and productive work time is improved.

The reduction in employee exposure to hazardous noise to below the OSHA 8-Hour Time Weighted Average alleviates employer’s need to modify employees’ current practices, reduces the likelihood of injury in the case of PPE failure, and ensures that personnel in adjacent “safe zones” are guaranteed to be safe from exposure.

Blast Ninja increases worker productivity

The OSHA noise standard (29 CFR 1910.95), a worker’s permissible noise exposure limit (PEL) is a time-weighted average (TWA) of 90 dBA for 8 hours. The standard also uses a 5 dBA exchange rate; so for every 5 dBA TWA increase in noise permissible exposure time is cut in half. The use of Blast Ninja nozzles increases production where OSHA time-weighted-average exposures rules limit operator exposure, reducing down time and excess costs associated with an asset.

Lowers air velocity, not particle velocity.

  • Durable, heavy-duty tungsten carbide construction
  • Expected nozzle life with expendable abrasives is up to 500 hours
  • Strip rate equal to, or better than standard nozzles
  • Reduction in hazardous noise exposure by 17 dB(A)
  • Greatly reduced incidence of operator hearing damage
  • Reduced OSHA noise citations

Blast Ninja nozzles set the new standard in performance, worker safety, and productivity.

Oceanit’s Blast Ninja system works by reducing the blast nozzle exit velocity while maintaining blast particle velocity. The particle velocity is of abrasives in typical blasting systems is only 30% of the air velocity due to the short acceleration distance available at this velocity. Particle velocity, which is important to productivity, is maintained through an innovative design.
