Overview
Whatever your rotorcraft, protecting your engine is essential to avoid costly damage and downtime. For decades, helicopter owners and operators have turned to Donaldson for superior engine protection, specifically IBF filters that use oiled media. We know every application is different, which is why we also offer a growing range of dry-media IBFs — giving you choices that can be tailored to flying conditions and maintenance practices.
Features
Oiled Media: Proven Performance
Oiled media filters have been the workhorse of inlet barrier filtration for more than 30 years. Donaldson was an early pioneer of oiled media use in commercial and military IBF applications, and it continues to be our primary media solution. Our oiled-media IBF offer low pressure drop and high-efficiency capture of a variety of contaminants encountered by rotorcraft air intake systems.
Dry Media: The Confidence to Fly Dry
It makes sense to choose your filtration the same way you choose your aircraft — by application and environment. That’s why Donaldson offers a range of certified dry-media inlet barrier filters, and it’s why we continue to develop and certify more.
A side-by-side comparison confirms that Donaldson IBF with dry media are measurably better than competitive dry-media offerings. Our dry media is more effective, efficient, durable and advanced than others in the market, directly contributing to meaningful reductions in maintenance requirements.
