Air filter Sprint Filter in polyester P08 for Ducati Diavel 1260 S 19-22

INNOVATIVE

The innovative polyester SPRINT FILTER P08 stands apart from all other special filters in cotton for its increased air permeability along with its more efficient filtration and easy maintenance. INCREASED AIR PERMEABILITY Diagrams clearly demonstrate that air permeability in comparison with that of a common special air filter in cotton is distinctly superior. The increase in air permeability and better performance in comparison with common special filters in cotton is mainly due to two essential elements: the filtering material is made of a structure in polyester and the filter’s folds are higher. These folds are what allow for the highest filtering surface on panel filters (20 mm) and work to the fullest advantage of air permeability and the quality of dirt filtration. Moreover, the total absence of oil to contain dirt allows for increased air entry with equal surface area. Furthermore, when considering that the filtering surface is very wide, an increase in air flow of approximately 25% is obtained in comparison with a cotton filter, working to the fullest advantage of the engine’s performance and the guaranteed protection of increased filtration.

EXTREMELY EFFICIENT FILTRATION

Besides its increased air permeability, SPRINT FILTER P08 ensures extremely efficient filtration: as much as 80 microns, allowing to sieve out 93.13% of 100 micron particles versus the 76.42% of 100 micron particles trapped by cotton filters. This is made possible thanks to the special structure made of 5 micron diameter yarns which are woven together to leave room for a wide surface in which air passes freely. This special structure creates a pattern that measures 80 microns. In comparison with an air filter in cotton soaked in oil to trap impurities, filtration efficiency and air permeability remain steady through time: the air filter in cotton needs periodic oiling and does not guarantee the same filtration efficiency and air permeability as our P08. Moreover, it is to be pointed out that oil permanency on an air filter in cotton during normal use is quite brief, to the disadvantage of engine protection.

EASY MAINTENANCE

Thanks to a structure that is practically indestructible, the SPRINT FILTER 08 air filter can be washed with any detergent, blown dry with an air compressor and immediately remounted without having to purchase additional maintenance kits or waiting for it to dry to then oil it. This is a dry filter and no oil needs to be added. Maintenance is quick and easy (2 minutes after opening the airbox).

TESTS

As clearly shown in these photographs taken using a microscope, the cotton filter is made of extremely coarse yarns while the polyester filter (P08) is made of much finer yarns sized to the micron. Thanks to this special design, polyester fabrics guarantee more efficient filtration and excellent air permeability as all our tests have shown. Nonetheless it is to be pointed out that the results obtained by testing cotton fabrics have not been 100% reproducible and this is due to the weak and yielding texture of the cotton gauze. However the following results are the best results we obtained. As to polyester fabrics, results have always been 100% reproducible and accurate.

AIR PERMEABILITY

Diagram N° l shows fabric air permeability at 20mm of H2O. Polyester shows higher values than cotton: 5,050 liter/m2s versus 4,900 liter/m2s.

FILTRATION EFFICIENCY

Diagram N° 2 shows the filtration efficiency of both fabrics. It is to be pointed out that tests have been carried out using water instead of air. And this gives a remarkable advantage to cotton whose fibers showed a higher degree of filtration efficiency thanks to their swelling. However polyester showed the best results: 93.13% of 100-micron particles have been sieved out versus 76.42% of 100-micron particles trapped by cotton.

These filters are different from original ones, first of all because using a cleaning kit they can be restored, then because let flow an 40% of air more than the original ones. Sometimes they could be more expensive than the original ones, but the initial cost will be optimized by their unlimited lifetime.

FAQ: the SPRINT FILTER is a racing filter? Yes but you can also use in street use.

FAQ: While install a filter do I have to change or modify something on my bike? No, these filters can only get a higher performance to your bike.
