DONALDSON FUEL FILTRATION SYSTEM SELECTED FOR NEW MARENCO SWISSHELICOPTER SKYE SH09

PARIS, France – JUNE 17, 2013 – Donaldson Aerospace & Defense, a division of Donaldson Company, Inc. (NYSE: DCI), has been selected by Marenco Swisshelicopter Ltd. to provide the fuel filtration system for its new, advanced-technology SKYe SH09 helicopter. 
The SKYe SH09 is an example of the next generation of light, single-engine helicopters and is designed to perform missions, including medical evacuation and other critical tasks, under the most extreme temperature and altitude conditions. The 5,500-pound (2.5-metric-ton), eight-seat helicopter incorporates an all-composite fuselage; a bearing-free, five-bladed rotor system; a SAGEM glass cockpit, and the newest electronically controlled, 1021-shaft-horsepower (760-kilowatt) turbine engine – the Honeywell HTS900-2. A product of Donaldson’s advanced filtration expertise, the fuel filtration system will protect that engine’s performance.

“Donaldson has long been committed to developing and applying the most advanced filtration technology for the protection of helicopter crews and passengers under the toughest conditions in the world,” said Pierre Habran, Director Aerospace & Defense at Donaldson Europe. “We are proud to share that commitment with Marenco and to support them in this exciting new project.”

For nearly a century, Donaldson has been developing and manufacturing lightweight, compact, advanced filtration solutions. Its products meet or exceed original equipment manufacturers’ specifications and international quality requirements and keep flight-critical aircraft components running efficiently and effectively. Customers count on Donaldson’s comprehensive product line to help them maintain mission readiness. With its proprietary technology and unmatched reputation for quality, service and reliability, Donaldson leads the way in meeting the unique filtration requirements of aerospace and defense customers worldwide.

Niederurnen, Switzerland-based Marenco Swisshelicopter was founded in 2007 for the direct purpose of developing, building and commercializing new concepts of light turbine helicopters. The company has started intensive component testing and plans to start SKYe SH09 flight tests soon, with the goal of introducing the new helicopter to service in 2015 after achieving certification by the European Aviation Safety Agency and the U.S. Federal Aviation Administration to the latest airworthiness and safety standards.
