Blast Nozzle Features Enhanced Noise Reduction

Kennametal Inc. (Pittsburgh, Pa.) recently announced an addition to its portfolio of abrasive blast nozzles for advanced surface preparation: the Blast Ninja. Designed by Oceanit, a Honolulu-based innovation company, the Blast Ninja is said to be a premium nozzle delivering improved productivity and enhanced hearing protection in a military-grade product that is compliant with OSHA guidelines. 

The Blast Ninja reduces air exit velocity while maintaining particle velocity, resulting in a significant reduction in noise production at the source while maintaining blasting production. This proven technology remains Kennametal-manufactured and is now available directly through authorized Kennametal distributors.

The Blast Ninja proprietary technology leverages years of research conducted on jet engine noise reduction and was developed along with the U.S. Air Force Research Laboratory (AFRL) and the U.S. Navy’s Office of Naval Research (ONR). Its patented design also offers enhanced hearing protection. 

• Compared to conventional venturi nozzles (outputting 115dB), the Blast Ninja has up to 17dB quieter noise output. This allows operators for more productive usage time per OSHA guidelines.

• In proper conditions, Blast Ninja can meet OSHA’s noise standard compliance 29 CFR 1910.95 of four hours of exposure.
