 
For heavy duty applications
Donaldson Endurance™ oil filters are made with premium advanced
synthetic media technology that results in fibers that have a
controlled size, shape and smaller fiber diameter.
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.

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. |
