DONALDSON FILTRATION SYSTEMS PROTECT AIRCRAFT FLYING IN MIDDLE EAST'S DEMANDING ENVIRONMENTS FROM DIRT, DUST AND SALT

DUBAI, United Arab Emirates – NOVEMBER 18, 2013 – Donaldson Aerospace & Defense’s Inlet Barrier Filters and other advanced filtration systems, reinforced by its expert customer support network, help aircraft throughout the Middle East perform critical missions reliably and safely in the region’s hot, dusty and salty conditions.

Donaldson Aerospace & Defense, a division of Donaldson Company, Inc. (NYSE: DCI), will be showcasing its systems and capabilities Nov. 17-21 during the Dubai Airshow at Dubai World Central (DWC) in Jebel Ali, Dubai, UAE. These will include the Inlet Barrier Filter (IBF) system for the AgustaWestland AW139 that is used by government and commercial operators in the Middle East. Donaldson IBFs also protect engines on Bell, MD and Sikorsky helicopters flown by numerous operators in the region.

The IBFs protect engines from microscopic dust and dirt while allowing flight crews to fly to Basic Inlet-equivalent performance and Category A operations levels. In addition, recent salt-water spray tests have demonstrated that Donaldson IBFs under extreme conditions can block nearly all airborne salts from entering an operating engine, further reducing maintenance costs and performance degradation.

“The Middle East presents some of the most challenging operating conditions in the world,” said Eric Erickson, General Manager at Donaldson Aerospace & Defense in St. Louis. “The experiences of our customers here demonstrate the ability of Donaldson’s advanced filtration technology and our customer support network to overcome those challenges and help their aircraft perform critical missions while reducing their costs of ownership.”

At the Dubai Air Show, Donaldson will be exhibiting with Global Aviation Services at Booth No. 2654. Under their new strategic alliance, Bahrain-based Global Aviation Services sells and supports Donaldson filtration solutions for aircraft as well as military ground vehicles in key Middle Eastern markets.
