Coming off a year of record sales for its industry-leading series of inlet barrier filters (IBF), Donaldson Aerospace & Defense is publicly debuting its IBF for the Leonardo AW169 this week at Heli-Expo 2024.

Donaldson launched its IBF line—which provides engine protection for helicopter operations, particularly those operating in harsh conditions—in 2001. Since then, the company noted that rotorcraft equipped with its IBFs demonstrate reduced engine maintenance costs, more consistent flight operations, and extended time-on-wing.

According to the manufacturer, its recent IBF sales have benefitted from increasing demand in helicopters used for defense and aeromedical missions.

“The success of our IBFs is a testament to our ongoing commitment to our helicopter OEM customers—listening to them and continually adding new products to support the industry,” explained Tom Newman, the company’s rotorcraft business director.

In addition to its lineup of legacy IBFs on display at its Heli-Expo booth, Donaldson is also showing off its new inducer vent filtration system for the Bell 407.
