Heli-Expo 2011: Donaldson Delivers 5,000th Inlet Barrier

March 7, 2011, 7:30 AM

Donaldson Aerospace & Defense, a division of Donaldson (Booth No. 4428), has Heli-Expo 2011 as the stage for delivery of its 5,000th inlet barrier filtration system.

The kit, for a Bell 429, will be delivered this month and Donaldson and Bell marked the milestone here at the Donaldson exhibit yesterday with hors d’oeuvres and beverages.

It was in 2006 that Bell Helicopter selected the Donaldson inlet barrier filter to protect the engines of new Bell 429s. Donaldson has also provided inlet barrier filters for the Army’s OH-58D Kiowa Warrior.

The St. Louis-based company’s aerospace filtration systems division has developed 18 such systems that are either military airworthiness release/qualified or FAA commercial certified.
