Donaldson Aerospace & Defense, a division of Donaldson Company, Inc. (NYSE: DCI) has received a Supplemental Type Certificate (STC) approval from Brazil’s National Civil Aviation Authority (ANAC) for an Inlet Barrier Filter (IBF) system for the AgustaWestland AW109 Power, Grand and Grand New (E/S/SP) helicopters. Donaldson produces the only IBF available for these aircraft. With ANAC certification, South American AW109E/S/SP operators now have the opportunity to realize the proven operating cost reductions and increased operational capabilities an IBF offers.

Donaldson’s AW109E/S/SP Inlet Barrier Filter will be on display in Exhibit 8451 during Heli-Expo 2012, Feb. 12–14 in Dallas, Texas.

Developed as part of Donaldson’s constant efforts to eliminate engine damage for helicopter operators worldwide, the IBF prevents engine damage in adverse and ramp environments alike. IBF-equipped AW109 Power and Grand operators can reduce aircraft operating costs without experiencing performance or drag penalties.

Donaldson Inlet Barrier Filter systems are already in use by AW109 operators worldwide in corporate, air medical and utility missions.

The IBF is a drop-in system with minimal installation impact. Features include 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 competitive alternatives. The IBF does not interfere with the sliding door on either configuration, and the filter design allows for quick removal and service.
