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. Clean fuel helps minimize expensive repairs and unplanned downtime. We offer fuel filtration products to protect your fuel systems – including injectors, pumps and engines.
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.
Donaldson lube filters keep oil clean by capturing contaminants that can cause engine damage. We carry a complete line of oil filters for diesel engines – in both standard life and Donaldson Blue® for extended service intervals.
Today’s modern equipment is designed to meet the highest performance standards. Donaldson air dryers are the right choice to help you operate in a safe manner and to keep your maintenance costs under control.
The sophistication of today's equipment requires higher fuel and fluid cleanliness levels than ever before. Donaldson bulk tank filtration systems help save on costly component replacement, prevent unplanned downtime and even prevent a decrease in fuel efficiency due to injector wear. Our bulk filtration systems reduce your total cost of equipment ownership.
Microscopic irritants like allergens, soot, dust and pollutants can find their way inside truck cabins, which can lower air quality. Donaldson cabin air filters remove irritants before they enter the vehicle cab, keeping the air you breathe cleaner. Durable, dependable and built for the long haul, Donaldson cabin air filters are constructed to the same quality standards as the original filter.
It's estimated that 40 - 50% of engine downtime is due to coolant system failure. And with today's diesel engines, coolant balance is key to keeping your engine running efficiently. Your engine coolant battles rust, scale formation, acidity, foaming, silicate drop-out and debris while it works to transfer heat and maintain the right operating conditions for optimal fuel economy. Our coolant filters allow you to choose the method that suits your maintenance practices and schedules.
For more than 50 years, Donaldson has been a leading supplier of exhaust systems, components and accessories for medium- and heavy-duty diesel powered equipment. Our exhaust system product line includes everything you need for a wide variety of on- and off-road applications.
