Finest nanofiber filter media for powerful engine intake air filtration

 The finest fibers for high performance

Nanofiber filter media from MBRT sets new standards for commercial vehicle air filters. It offers an extremely high dust separation efficiency of up to 99.99% for the separation of particles together with low flow restriction and a long service life.


Combustion air always contains particles which should not be allowed to penetrate the inside of the engine. The application of a highly efficient air filter is therefore essential in order to protect the engine and its components such as the turbocharger or mass air flow sensor against increased wear and defects caused by dirt particles.

MBRT develops nanofiber coated filter media for the highly efficient separation, also amongst others, of fine particles. These filter media from MANN+HUMMEL are characterized by a verifiably higher separation efficiency along with the high dust holding capacity.

A high-tec nanofiber coated filter media from MBRT is the first choice for vehicles which work in environments with a high level of soot or fine dust pollution. Typical application areas here are dusty construction sites, mines and car rallies.


Good particle separation performance along with low flow restriction

MBRT has successfully used nanofiber technology for a number of years in series applications for the commercial vehicles sector. The nanofiber filter media consists of a carrier media and an extremely thin layer of ultra-fine polymer fibers. The fibers with a diameter of less than one micrometer are approximately 200 times smaller than the fiber diameter of the carrier material. This leads to a considerable improvement in particle separation. At the same time nanofibers offer a further advantage: In spite of the high separation efficiency, the flow restriction remains very low. 

A comparison of the nanofiber filter media to the carrier material on its own demonstrates the performance which nanofiber technology offers filters. In the test of filter elements according to ISO 5011, nanofiber filter media retained up to 10 times more dust compared to the carrier material on its own. Standard media made from cellulose enable the separation of 99.9% of the total mass of dust particles in the air.  The closely meshed nanofiber layers allow separation efficiency to rise to 99.99%.
