Donaldson Debuts R66 Inlet Barrier Filter
The Donaldson inlet barrier filter system will be available as an option from Robinson on new orders or as a retrofit.

Donaldson Aerospace and Defense has received FAA certification for the first inlet barrier filter (IBF) for the Robinson R66 to provide added protection for engines operating in dusty environments, the industry filtration specialist announced. The filter, designed for year-round usage, will be available as a factory option on new helicopters for $6,500, or as a retrofit to existing R66s. The installation includes a pre-flight sight gauge to observe how dirty the IBF is. Service interval for the oil-media unit is 300 hours or annually, depending on operating conditions.
