  • Environmental Control Systems (ECS)

Donaldson provides clean air solutions for crew and cabin environments.DonaldsonBanner1
We provide both chemical and particulate filtration for these critical

Our High Efficiency Particulate Air (HEPA) filters meet or exceed the OEM
specifications for aerosol particulate removal. Donaldson HEPA filters
and traps dust, lint, pollen, smoke, bacteria, viruses, spores and other

Our chemical filters allow us to remove chemical irritants that can be
found on aircraft. Donaldson’s latest advancement is our Air Purification
System™ (APS) technology. This filter combines a HEPA filter and
gaseous purification system.


  • Electronic Equipment Filtration

Electronic Equipment (EE) compartment filters are designed to remove
lint and bother particles from the avionics equipment cooling systems.
Contamination causes higher operating temperatures, which can lead
to premature equipment failure.

  • Air Drying Systems
  • Avionics Cooling
  • In-Flight Entertainment Systems (IFE)




  • Donaldson Rain Repellent™

Rain Repellent provides better visibility during rainy condition. Rain
Repellent is CFC free.


  • Pneumatic Systems Filtration

From commercial jets to single engine planes, our engineers work
closely with the aviation industry to design pneumatic system filters that
operate at the highest efficiencies. We have filters for lavatory, potable
water and other compressor systems.


  • Engine Liquid Filtration

When your liquid filters are right, you know you’ve got peak engine and equipment performance. Today’s equipment is built to more stringent specifications and finer tolerances. Donaldson delivers innovative designs, a complete product line, and performance that meets or exceeds OEM specifications. We offer an extensive line of liquid filtration for main engine
and Auxiliary Power Units (APU). We design T-type filters and manifold that include indicators, valves and sampling ports for coolant, fuel, lube oil and transmission systems.


  • Fuel Filtration

Fuel systems, pumps, and injectors require cleaner fuel to achieve betterDonaldsonBanner2
combustion and lower emissions. That’s why the latest advances in filter
media can make the difference between power and efficiency.
