On-road or off-road, you can trust Donaldson air filters to withstand whatever the environment throws their way.  Since 1915, Donaldson has pioneered the development of nearly every major advancement in heavy-duty engine air filtration. Nothing else protects, performs and provides longer life for engines than our industry-leading filters.

Our fuel filters help keep your engines and equipment running smoothly. Today‘s diesel engines need to maintain high performance levels to remain compliant with stringent emissions regulations. Fuel filtration plays a key role, with current high pressure common rail fuel injectors operating at pressures up to 2,000 - 3,100 bar / 30,000 - 45,000 psi. 

We have the right filters, contamination control products and capabilities to protect machinery and components in hundreds of applications – in the factory and on heavy-duty equipment. When you need hydraulic filtration, turn to Donaldson.
