On-road or off-road, you can trust Donaldson air filters to withstand whatever the environment throws their way. Since 1915, Donaldson has pioneered 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.

Donaldson offers two primary tiers of air filter products for heavy-duty applications, including:

Donaldson Standard OEM-Grade Air Filters: The Industry Workhorse 

Many leading OEMs ship their mining, construction, agricultural, and transport equipment with Donaldson’s cellulose air filters as factory first fit.    

• Precision-engineered to achieve OEM airflow and restriction requirements.
• Perfect for well-maintained machines operating in manageable dust conditions.
• Proven reliable, consistent performance.
• Performance of basic tasks is cost-effective.

Donaldson Blue® Premium Air Filters: For Hostile Operating Environments

Donaldson Blue® air media are manufactured with a cellulose substrate surface coated with Ultra-Web® fine fibre technology. The clear advantages are field-proven: 

• Superior air cleanliness from installation to element capacity.
• Enhanced fine contaminant performance, maximising engine protection.
• Ultra-Web® surface loads dust rather than loading the cellulose substrate.
• Donaldson Blue® air media provides lower air intake restriction for longer than cellulose 

Donaldson also offers media options specifically designed to perform across a wide range of heavy-duty applications

UL-approved flame-retardant air media suited to environments with combustible dusts or subjected to ember attacks.
