Overview
Help protect your aircraft lubrication systems from contamination to keep critical components running smoothly with Donaldson lube oil filters. We offer a broad range of custom oil filters and assemblies for all your commercial aircraft and rotorcraft engine and gearbox needs.
With more than 100 years of filtration innovation, we have the capabilities and experience to develop, qualify and certify aircraft oil filters and assemblies.
Features
Whether you’re an engine manufacturer or a rotorcraft airframe manufacturer, we can create the custom oil filters and assemblies you’re looking for. We offer filtration systems for main engines, auxiliary power units and gearboxes and only use media (typically cellulose-based or fiberglass-based) that has been qualified to perform in aerospace applications.
Custom Solutions for Lubrication Systems
Contamination in aircraft lube oil systems comes primarily from combustion byproducts and heat. Large turbofan engines typically have a one- or two-filter lubrication system. A two-filter system normally has a main lube filter and a scavenge filter, both of which are usually low-pressure filter cartridges fitted into a simple housing or a manifold integrated into the engine.
We develop custom solutions for your application (unless an engine is applied in multiple applications). With extensive experience in finishing castings from other companies, as well as casting our own low-pressure lube systems, we can develop an engine lubrication system specifically for your needs.
APU Filtration
Commercial aircraft and rotorcraft both have auxiliary power units (APU) that run secondary systems when the aircraft main engine isn’t on. In addition to developing lube manifolds, Donaldson offers PMA replacement parts (in some regions) for both commercial aircraft and rotorcraft APU applications.
Filter Out Internal Gearbox Contamination
Gearboxes are generally closed or sealed systems, so contamination typically comes from internal wear. Some gearboxes may be vented to compensate for atmospheric changes, and these vents can also introduce contamination. Help prevent contaminants from affecting gearbox function with our custom lube filtration manifolds for commercial aircraft as well as will fit PMAs for rotorcraft.
