Compressor Filtration

On-road or off-road, in all kinds of operating environments, Donaldson air filtration technology protects engines, delivers longer filter life and gives you the confidence that come with using the industry leader. Donaldson has pioneered the development of nearly every major advancement in heavy-duty engine air filtration since 1915. We set the standard for filtration performance.


Air / Oil Separators

Air / Oil SeparatorsDevelopment and customized design of air/oil filtration systems improves compressor performance. A new laboratory helps us to continually improve our technology.

Air / Oil Separators

Our full range of traditional wrapped and pleated media separators deliver high filtration efficiency and longer life, plus boast greater energy efficiency too.

Media Technology for Air/Oil Separation

Donaldson Formix™, our newest air/oil separator technology is a true depth media that delivers improved performance in less space. Lower restriction results in lower energy usage.


Air Filtration

We’ve got a rich history of air filtration and we’ve incorporated that knowledge into our compressor products. We’ve utilized advanced filtration technologies to keep our product on the cutting edge. Donaldson can provide you the most advanced intake systems and filtration media technologies for your compressors.

Air Cleaners / Housings

Air FiltrationDonaldson recommends the use of our housings with RadialSeal sealing technology for compressors. Our FPG style housings are ideal because they’re reliable, durable, plastic and easy to service. Many air cleaners are stock product, but custom design support is also available

Unique Air Filtration Technologies

Air FiltrationDonaldson has two air filtration media technologies that offer performance and overall size benefits. If you’re looking for higher efficiency, Donaldson Ultra-Web nanofiber technology may be a solution or if you’re looking for a smaller size with your existing filtration performance, Donaldson PowerCore™ filtration technology may be the answer.

Replacement Air Filters

Air FiltrationClean, unrestricted airflow is critical for optimal compressor operation. Higher airflow reduces energy use. Donaldson delivers increased contaminant protection, reducing engine damage. Replacement compressor products are available through compressor dealers or Donaldson distributors. Donaldson offers a full line of air filters in all shapes, sizes and styles.

Liquid Filtration

Today’s compressors last longer and operate in more severe conditions than ever. These improvements demand lube and fuel filters with heavy-duty design characteristics and optimum performance.

Lube Filters

Lube FiltersDonaldson can design and manufacture lube housings and filters for compressor systems. We have over 26 types of cellulose and Synteq™ (synthetic) media that deliver an array of filtration performance.

Exhaust and Emissions

Exhaust and EmissionsIf you have stringent standards for emissions and noise levels, Donaldson has the analytical tools and engineering expertise to help meet your performance requirements. Look to us for help!


System Design

Donaldson develops and designs unique filtration systems that help you achieve superior compressor performance. Donaldson has the unique ability to offer total system design including separator systems, separators, air intake, lube filtration and exhaust. Our new compressor testing facility enables engineers to easy access to a numerous design and analytical tools.

Separator Systems

Separator SystemsWhen your pressure vessel and separator are designed together, your separator system will deliver optimum performance. Combine our design expertise with Formix™ media technology and Donaldson will be able to help you reduce the overall size of your separation system.
