Donaldson Aerospace & Defense has received Federal Aviation Administration certification of a new inducer filter technology for Bell Helicopter 407 engines. Donaldson displayed and began taking orders for the Inducer Vent Filter (IVF) during Heli-Expo 2014. The IVF is certified and available for retrofit and for installation on new-production 407s.
The IVF provides protection at the centrifugal compressor bleed slot for the Rolls-Royce M250 engine that powers the Bell 407 – including the latest model, the 407GX. It offers operators of 407s equipped with Donaldson’s Inlet Barrier Filter (IBF) system the added ability to help prevent costly contaminant and foreign object damage of the M250’s compressor, supplementing the substantial protection provided by the IBF system to provide 100% inlet protection. By reducing compressor wear, the IVF will also reduce engine maintenance and inspection costs and extend times between overhauls.
