Donaldson designs, manufactures, and markets advanced air inlet filtration systems for gas turbines, generators, and other rotating equipment. Our systems and related air inlet products protect turbines from airborne contaminants in thousands of systems around the world.


Complete Intake Systems
Donaldson has the expertise and the tools to design and to supply entire air intake systems such as to protect the long term operating performance of the machine, with services all over the world
Self Cleaning Air Filters
Donaldson self-cleaning systems are designed to help turbines & generators operate anywhere – in dusty deserts, urban/factory areas, on the coast, in the frosty north. Because they are self-cleaning, they require little maintenance between filter change-outs.
Static Air Filters Static Air Filters
Donaldson static air filtration systems are unique. Often chosen to protect inlet air on turbines and generators in urban, industrial, offshore, marine, and coastal environment, they are maintenance free in the sense that the fine filter elements change-out is matching with the major turbo-machinery overhaul thanks to the extended filtration media area and the enormous dust holding capacity
Inlet Silencers Inlet Silencers
Donaldson provides with innovative solutions to meet the total system designs economics in most challenging site noise limit conditions. The machinery long-term protection remains paramount as well as its operating cost.
This requires specific expert knowledge in this particular turbo-machinery protection field. Donaldson is your total air intake system partner
Inlet Ductings Inlet Ductings
Donaldson owns a long time expertise in the Gas turbine protection field. The mastering of modern computation and visualisation tools allows for designing towards the best operating conditions while insuring strength against steady and even, pumping flow conditions.
The global presence of Donaldson over the globe provides with lowest transportation cost and the best economics for the project.
Inlet Anti-Icing Systems Inlet Anti-Icing Systems
Donaldson supplies a variety of means to inject heat within the air systems either upstream or downstream the air-filters
Air-Inlet Cooling Systems Air-Inlet Cooling Systems
Donaldson supplies power enhancement devices compatible with the air intake filters: evaporative, chillers…
The financial return on the added capital investment guaranties incredible payback periods
Cartridge Filters Cartridge Filters
Whatever brand cartridge-style filter house you have, we have a filter for you. If you didn’t get Donaldson filters originally, try upgrading to Donaldson Spider-Web, our patented nanofiber media technology, for higher efficiency filtration and better turbine output, or Spider-Web XP for extra performance.
Panel Filters Panel Filters
Replacement panel filters to fit a variety of Donaldson and
non-Donaldson air inlet systems.

Pre-Cleaning Filters Pre-Cleaning Filters
Pre-filters -- both wraps and panels -- have the job of extending the life of the primary filter by capturing larger particulate, such as seeds, leaves, airborne fibers, etc. They are made of low-cost, relatively low efficiency materials, and are designed to be changed more often than primary filters -- then thrown away.

Air Inlet Enhancements Inlet Air Enhancements
Gas turbines are not often installed in ideal environments. Your turbine may face challenges from hot weather, cold weather, fog, sand storms, salt-laden air, and/or noise abatement regulations, to name few. Or, perhaps it’s simply time to update & upgrade an old system. Donaldson offers inlet enhancements to help overcome challenges and keep your turbine producing its optimum output for many years.
