THANK YOU FOR CHOOSING INDUSTRIALVALET. HAPPY SHOPPING!
Donaldson, the company that invented air filters for heavy-duty diesel engines almost 100 years ago, was also the first to develop nanofiber air filter media for the diesel engine market nearly 20 years ago.
â¢ Engineered to perform in extreme temperature and humidity conditions, unlike ordinary nanofibers
â¢ Proven in the real world – used in diesel engines for nearly two decades
â¢ On-highway trucks are guaranteed to go twice the distance compared to standard cellulose filters
Longer Engine Life
In laboratory and field tests, Donaldson air filters provided better engine protection by allowing much less contaminant to pass through than cellulose air filters. Donaldson air filters also reach an optimal 99.97% efficiency much quicker than conventional cellulose filters – and have an overall ef ciency up to 99.99%! Equipment owners using Donaldson filters with Ultra-Web media experience improved engine protection and power, plus lower overall life-cycle costs.
Longer Filter Life
The smaller interfiber spaces of Ultra-Web® nanofiber technology hold more submicron contaminant than conventional filters with cellulose media. The high dust-holding capacity of submicron particles promotes longer filter life.
