Donaldson Aerospace & Defense has equipped a Scandair Eurocopter AS350B3e and a Summit Air Ambulance AgustaWestland AW109 with inlet barrier filter (IBF) systems. The Swedish utility operator provides aerial applications, including in “very dusty environments while fertilizing, and the indicator still shows good filter performance,” according to owner Fredrik Ulander.
Summit Air Ambulance, based in Idaho, was the first operator to incorporate a Donaldson IBF into an AW109E. The system is also designed to cover the S (Grand) and SP (GrandNew) variants. Summit assisted Donaldson with the initial flight testing and certification of the IBF on the AW109. Larry Bacus, senior vice president of Summit—which conducts high-altitude rescues in Idaho, Nevada and the western U.S.—noted that the IBF “enhances our safety program.”
