Donaldson to Certify New Barrier Filters for AgustaWestland, Eurocopter Aircraft in 2010

St. Louis, Mo., Feb. 19, 2010 – Donaldson Aerospace & Defense, a division of Donaldson Company, Inc. (NYSE: DCI), continues its leadership in helicopter engine protection solutions, introducing two important new products. Donaldson Aerospace & Defense is developing Inlet Barrier Filter (IBF) systems for the AgustaWestland AW109 Power and Grand as well as the Eurocopter EC135. Soon, worldwide operators of these aircraft will be able to eliminate the high costs of engine damage and have access to the best engine protection available. Officials anticipate certification in 2010.

The EC135 IBF system features multiple long-life filter assemblies that are internally mounted to the existing EC135 cowlings, resulting in no drag penalties and no potential for environmental harm associated with externally mounted designs. The AW109 IBF will have dual applicability for the Power and Grand, utilizing conformal filters with proven filter media to virtually eliminate debris ingestion. Both new systems feature an integral inlet bypass system that allows mission continuation in the event of filter obstruction. Watch for further updates on these exciting new products.

Operators worldwide know they can turn to Donaldson Aerospace & Defense to protect their aircraft power plant and other vital systems.
