Inlet Barrier Filter for AgustaWestland AW109E/S/SP

March 03, 2011
March 3, 2011, St. Louis, Mo., – Donaldson Aerospace & Defense, a division of Donaldson Company, Inc. (NYSE: DCI), will display its new Inlet Barrier Filter (IBF) system for the AgustaWestland AW109 Power, Grand, Grand New (E/S/SP) helicopters during Heli-Expo 2011 (Exhibit 4428) in Orlando, Fla., March 6-8, 2011.

With this new IBF solution, AW109 Power and Grand operators will enjoy reduced operating costs without expriencing performance or drag penalties. Company officials are working towards U.S. Federal Aviation Administration (FAA) certification this spring and have completed initial company flight testing.

“We are proud to offer a proven barrier filtration solution for this sleek and speedy helicopter,” said Michael Scimone, president of Donaldson’s St. Louis operation. “What we have developed, with the assistance of AgustaWestland, is a drop-in IBF system with minimal installation impact.”

The new IBF system for the AW109 features streamlined conformal filter assemblies on each side, mounted into the existing engine cowl. As with all certified Donaldson IBFs, the system includes an alternate inlet air bypass system, mounted and hidden within the AW109 upper aft fairing. This emergency bypass capability is an important IBF feature, not included with particle separator alternatives. The IBF does not interfere with the sliding door on either configuration, and filter design allows for quick removal and service.

A simple compact cockpit switch, common with existing Donaldson certified systems, allows indication and activation of the bypass system. And, as with all Donaldson IBFs, an integral Filter Maintenance Aid allows for on-condition inspections pre- and post-flight. A new access panel has been added for easy access to the bypass system and maintenance aid so pilots and ground crew may perform quick and simple pre-flight assessments.
