High Performance System Helps Prevent Engine Damage

Aerospace Filtration Systems has received an STC from the FAA for an Inlet Barrier Filter (IBF) system for the AgustaWestland AW139. This new IBF prevents engine damage in adverse and ramp environments alike.

Donaldson's Aerospace and Defense Group, Aerospace Filtration's parent company, partnered with AgustaWestland to ensure the system addressed the AW139's operational requirements. After successful joint development of the IBF for the AW119 series, Donaldson's engineering department worked closely with AgustaWestland's technical team to refine the AW139 IBF design.

"Listening to our customers' needs and providing second-to-none customer support is critical to our team," commented Mike Scimone, President of AFS. "Responding to operators and AgustaWestland priorities, we came up with a plan to provide an expedited and superior engine protection solution."

The new AW139 IBF system features low profile conformal fore and aft fairings with dual filter assemblies mounted on the existing engine doors, creating a sealed intake plenum. As with all certified Donaldson IBF's, the AW139 system includes an alternate inlet air bypass system. This emergency bypass capability is an important IBF feature and is absent in most traditional sand filters and particle separators. A simple compact cockpit switch allows indication and activation of the bypass system. An integral Filter Maintenance Aid also allows for on-condition inspections pre- and post-flight to assist in mission planning and visual inspection of filter condition.
