Donaldson Endurance™ 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.

Endurance™ air filters deliver cost-saving benefits: |
• Longer Engine Life
• Longer Filter Life
• Ideal for Extended Maintenance Intervals
• Cleanable With Shop Air for Reinstallation
• Double Mileage Guarantee |
| Endurance
Cross Reference |
These air filters also are reusable. When the restriction gauge
indicates replacement, the filter can be removed from the air box and
cleaned with shop air up to five times.
Donaldson Endurance™ air filters are guaranteed to deliver twice the
miles between change intervals over cellulose air filters for on-highway
applications or customers receive a new filter at no charge.

Donaldson Endurance™ Air
Filters With Nanofiber vs. Conventional Cellulose
|
|
Nanofibers
have submicron diameters and small interfiber spaces, which
result in more contaminant being captured on the surface of the
media and lower restriction.
|
Red circles
represent the diameter of a 2 micron and a 5 micron particle.
|
Cellulose
fibers are larger than nanofibers, and have larger spaces
between the fibers, causing contaminant to be held in the depth
of the media and plug the airflow path; resulting in higher
restriction and less capacity.
