Overview
Effective hydraulic filtration requires tailored system designs—there is no one-size-fits-all approach. That's where Donaldson excels for you. Whether it’s a simple T-type manifold or a complex, multiple-circuit filter manifold assembly, we have the expertise and certifications to manufacture aircraft hydraulic oil filters and assemblies that meet the needs of your hydraulic system, helping to protect critical components and improve your overall aircraft maintenance experience.
Hydraulic Filters for Multiple Aircraft Applications
To accommodate your system’s filtration requirements, Donaldson offers multiple design options for aircraft hydraulic oil filter assemblies.
We design aircraft hydraulic fluid filters with manifolds to OEM or supplier specifications, and we can produce PMA filters or aftermarket requests from end users. We offer innovative filtration media, component integration and system flexibility for both OEM and aftermarket applications.
Our aerospace hydraulic applications are mostly pressure, return and case drain filters made from aluminum. Depending on the system design, they can be built into either a single manifold or separate stand-alone assemblies. Our larger platforms typically have multifunction manifolds, which are space- and weight-saving and are easy to service.
Custom Features Available for Manifold Assemblies
- Intricate head design
- Multiple filter bowls
- Filter elements
- Bypass valves
- Shut-off valves
- Check valves
- Fluid sampling ports
- Differential pressure indicators that signal end of life
Our manifolds typically include multiple filter elements clustered together so that several functions can be completed in a smaller space with lower weights in mind. For less complex needs, we also offer smaller, single-function filter assemblies and housings.
Hydraulic Filters for Fixed-Wing Aircraft and Rotorcraft
For commercial fixed-wing aircraft, we offer assemblies, manifolds, and replacement filters, plus a selection of replacement filters compatible with many applications and brands. Additionally, we can supply reservoir filling filters with a small assembly to be used when refilling the reservoir during maintenance
We also have the expertise to develop rotorcraft hydraulic filters and assembly systems that are similar to business jet and fixed-wing aircraft applications. This includes filters and assemblies for flight control hydraulics, hydraulic actuators or pistons, and servos or control valves that control direction and flow rate.
