finecellulose fiberfor general purposes

Donaldson Blue® air filters with Ultra-Web® fine fiber technology protect engines by providing better initial and overall efficiency compared to conventional cellulose media. We invented air filters for heavy-duty diesel engines more than 100 years ago and were the first to develop nanofiber air filter media for diesel engines more than 20 years ago. Today, we continue to innovate with Ultra-Web® HD, built specifically to perform better in heavy-dust environments. Available Media Types Ultra-Web® Fine Fiber Technology Engineered to perform in extreme temperature and humidity conditions, unlike ordinary nanofibers Proven in the real world – used in diesel engines for nearly two decades On-highway trucks are guaranteed to go twice the distance compared to standard cellulose filters Ultra-Web® HD Ultra-fine Fiber Technology Designed specifically for heavy-duty, heavy-dust environments — like mining. Provides greater efficiency than previous generation nanofibers Provides the best protection for high-dust applications Benefits Longer Engine Life - Donaldson Blue® air filters provide better engine protection by allowing much less contaminant to pass through than cellulose air filters Longer Filter Life - Smaller interfiber spaces of Ultra-Web® fine fiber technology hold more submicron contaminant than conventional filters with cellulose media, delivering longer filter life Applications On-road trucks Off-road trucks and equipment
