Ultimate Performance, Ultimate ProtectionModern fixed-and rotary-wing aircraft components run at higher temperatures and use new fuels and
lubricants that require more advanced liquid filtration technologies. Specifically, modern aviation systems
require pristine fuel and lubrication so that system pumps and injectors can operate effectively, achieve
better combustion, and lower emissions. Donaldson liquid filtration systems protect fluid circuits—such
as hydraulic, coolant, fuel, lube/oil and transmission fluid components—from destructive contaminants.

Donaldson liquid filtration ranges in complexity—from a simple t-type
manifold to a complex, multiple circuit filter manifold assembly—
which may include an intricate head design, multiple filter bowls, filter
elements, bypass valves, shut-off valves, check valves, fluid sampling
ports, and differential pressure indicators. Whatever platform powers your military or commercial
aircraft, custom-designed liquid filtration solutions from Donaldson are lightweight, require minimal
service and help lower the total cost of ownership.
Donaldson fuel filters are manufactured using advanced technology processes.
