AMSOIL® Introduces Donaldson Endurance™ Oil and Air Filters with Nanofiber Technology

AMSOIL INC.® of Superior, WI now represents the Donaldson Endurance™ lube and air filters with nanofiber technology. Donaldson filters are specially designed for GVW Class 6, 7 and 8 over-the-road commercial vehicles including vans, beverage trucks, school buses, box trucks, tow trucks, city transports, fuel trucks, cement mixers, heavy construction cabs, refrigerated vans, and more.

This unique nanofiber technology traps sub micron containment below 1 micron in size (a human hair is 50-80 microns in diameter). Donaldson Endurance air filters utilize a sub micron, ultra-fine web that captures these fine contaminants at a very high efficiency level. Donaldson Endurance air filters from AMSOIL® provide the following cost saving benefits:

• Longer engine life
• Longer filter life
• Extends maintenance intervals
• Twice the distance guarantee

Donaldson Endurance lube filters are made with premium advanced synthetic media that incorporates sub micron fibers in size, shape and fiber diameter. The Donaldson Endurance lube filters from AMSOIL® provide the following cost saving benefits:

• Extended service life
• Superior engine protection
• Improved lubricant flow
• Improved cold starts
• Reduced operating costs

Donaldson Endurance™ Oil Filters

Product Code: ELF

The controlled media manufacturing process allows Donaldson Endurance™ oil filters to deliver both higher dirt holding capacity at the same pressure differential and higher efficiency compared to conventional cellulose filters. The synthetic media also has better durability with usage.

Throughout the service life of a cellulose filter, hot oil will degrade the resins that bind the media. The synthetic media technology uses a wire screen backing pleated with the media, resulting in superior strength.

Donaldson Endurance™ oil filters offer extended service intervals, greater engine protection to prolong engine and equipment life, improved lubricant flow, improved cold start performance and lower operating costs.

Donaldson Endurance™ Oil Filters With Nanofiber vs. Conventional Cellulose
Small, consistent synthetic fibers trap smaller particles and hold more contaminants, resulting in lower restriction.		Cellulose fibers are inconsistent in size and shape, allowing more contaminants to pass through, resulting in higher restriction and lower capacity.

Donaldson Endurance™ Air Filters

Product Code: EAF

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.

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.
