Donaldson banking on dry media filtration technology

October 14, 2014  By Carey Fredericks

Oct. 14, 2014, Amsterdam, Ned. - Donaldson Aerospace & Defense is bringing its battle-proven dry media technology to the commercial helicopter market. The company is flight testing its next-generation non-woven dry media on MD 500s equipped with Inlet Barrier Filters (IBFs) and will certify and offer the technology as an option for a range of popular commercial helicopters.

Donaldson’s dry media uses the company’s proprietary nanofiber technology to provide 99 per cent particle separation. It has been battle tested for more than a year on U.S. BLACK HAWK helicopters in Iraq. Donaldson’s nanofiber filtration stops contaminants from reaching the engine while maintaining engine performance.

“By offering dry media to the commercial market, Donaldson is ensuring that operators have a range of quality options,” said Robert Stenberg, Donaldson St. Louis Business Development Director. “We work in partnership with our operators to help them evaluate and choose the solution that is right for them.” For example, dry media is preferred for high tempo operations, while oil-coated is ideal for those flying in more normal, less extreme environments.

And because dry media can be vulnerable to higher pressure drops, Donaldson is applying its highly advanced research and development capabilities to ensure that its commercial product meets exacting standards for OEM quality and performance. “There is no room for compromise,” Stenberg said. “Every operator should have superior engine protection.”

Current and prospective customers can discuss Donaldson’s advanced filtration technologies with company experts at the Donaldson exhibit C11, during the Helitech International Helicopter Expo & Conference, October 14-16, 2014, in Amsterdam.
