Donaldson Company, the worldwide manufacturer of filtration systems and parts, recently released more than 50 Donaldson Endurance air filter sizes that are now available for off-road applications. Manufactured using Donaldson’s advanced Ultra-Web nanofibre technology, these air filters are described as “the best choice for off-road applications as they help reduce maintenance costs and increase equipment uptime.” Donaldson Endurance air filters protect engines and help them last longer by providing better initial and overall efficiency compared to conventional cellulose media.The company states that off-road customers will see several advantages including ultra-long filter life. With the use of ultra-web nanofibre technology, submicron contaminants load on the surface of the filter media instead of dispersing throughout the depth of the filter where there is less area for air to flow. This high dust-holding capacity promotes longer filter life. Other advantages include ultra-high efficiency and ultra-engine protection – Donaldson Endurance air filters reach 99.97% efficiency quicker than conventional cellulose filters and have an overall efficiency up to 99.99%. As a result, Ultra-Web filters for off-road equipment provide improved engine protection and can deliver increased power and lower life cycle costs, according to Donaldson.
