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 latest products, the expertise and the tools to design and to supply entire air intake systems up to the nose of the turbine. Our smart solutions protect and give the best long term operating performance to all your rotating equipment, in any environment around the world.

Self-Cleaning Air Systems
Donaldson self-cleaning systems are designed to help turbines and 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. They are often chosen to protect air inlet for turbines and generators in urban, industrial, offshore, marine, and coastal environments. They are virtually 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 silencing solutions to meet the total system designs economics in most challenging site noise limit conditions and airflow resistance requirements. 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 air treatment products to increase your turbomachinery power output and efficiency, in addition these products are compatible with the air intake filters. The financial return on the added capital investment guarantees incredible low 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 nano-fiber media technology, for higher efficiency filtration and lower operational pressure loss, both parameters result in better turbine output. Spider-Web XP is our newest type of nano-fiber media increasing even more your GT performance.

Cartridge Filters Compact Filters

The static compact filters NorrVee and NorrCel are particularly designed for air intake applications for gas turbines and other rotating equipment. The media consists of microfine glass fibres and the filters are available for efficiency levels up to grade F9 per EN779:2012 and up to H13 as per EN 1822:2009.

Pulse Filters Pulse Filters

NorrPak pulse filters are high-efficiency panel filters used in self-cleaning systems. They have a high dust-holding capacity, a long filter life and can be provided with different Donaldson filter media grades to meet up to F9 per EN779:2012 and E11 per EN1822:209.

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 have to operate in any climate and environment. 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.
