Donaldson Endurance™ Air Filters for heavy duty applications

Donaldson Endurance™ air filters deliver cost-saving benefits:

• Longer Engine Life
• Longer Filter Life
• Ideal for Extended Maintenance Intervals
• Double Mileage Guarantee

Donaldson EnduranceT Air Filters with exclusive nanofiber technology offer longer engine life, longer filter life, initial efficiency up to 99.99 percent and five times more capacity.

The nanofiber technology causes submicron contaminants to be held on the surface layer of smaller fibers. This filtration characteristic is only possible with this new type of air filtration technology. In on-highway applications, where the contaminant is primarily submicron in size, Donaldson Endurance filters cause less restriction than conventional filters with cellulose media. The smaller interfiber spaces of nanofiber technology have a higher efficiency and capture more contaminant.
