DNA Test & Results
The DNA Flow and Dyno Tests.
We test every single filter. Satisfaction guarantied.
The DNA Air Flow Tests
For the air flow tests, we use the most advanced flow bench available today.
The ROTRONICS FlowScan, is a totally computerized flow bench that measures:
- Mass of the air,
- Flow of the air,
- Temperature of the air,
- Absolute air pressure,
- Differential air pressure,
- Speed of the air at various points (Pitot tubes),
- Absolute humidity of the air.
The complete procedure is automated and computer controlled, eliminating human errors.
The DNA Dyno Tests
For the Dyno Tests, we use the industry standard Dynojet chassis dyno equipped with eddy current load control, Dynojet 250LC. Our dyno cell is equipped with a variable flow air cooling system, designed to precisely simulate real world conditions.
The DNA High Performance Air Filter in action
It is a dirty job, but somebody has to do it!" Find out how a DNA High Performance Filter works to protect your engine efficiently, without compromising performance!
Human "technology" inspiration!
The "technology" that our DNA filter uses to clean the air is surprisingly common to all of us. It is part of our body; we use it constantly to stay alive! It is part of the Human respiratory system that filters the air we inhale! Tiny moistened hairs called cilia protect the nasal passageways and other parts of the respiratory tract, filtering out dust and other particles that enter the nose with the breathed air. The DNA filtering cotton media is exactly that, millions of tiny fibers that are oiled!
The "hairy hybrid" as we call it, is a genius combination of cotton fibers per square millimeter. The Tex & Thread, of this unique cotton, is a result of intensive research, by DNA's development engineers. The "hairy hybrid" impregnated with DNA's special filter oil, is transformed into the remarkable DNA media that provides very high filtering efficiency and extremely high flow rates.
Trap "enemies" by static charge!
We designed the DNA Filter to acquire a positive static charge as the air passes through the pleated and oiled filter media. The weak static charge will very efficiently "pull" on the oiled cotton fibers, the debris and dust that are in the air; remember in science class at school, the pen rubbed against wool that can attract small bits of paper, experiment? This is exactly what happens, as the air flows through the filter, debris even as small as 5 microns will change course and stick onto the fibers, regardless if the "holes" between the fibers can be as large as 150 microns! The first layer of debris on the fibers will then absorb some oil, get statically charged and become part of the filtering media! And guess what, it will start attracting new debris assisting the cotton media in its filtration chore!Finally debris will continue building up on the surface of the filter, as air passes through, until it is totally covered (see photos below).
Extreme testing environment.
Our filters have being successfully tested even in the harshest environments during the DAKAR Rally! Through Argentina up to the Andes, and down to the Atacama Desert in Chile. The dreadful "Fesh-Fesh" (Guadal) fine powder desert sand of the Atacama Desert, was succesfully kept out of the race engines, outperforming the foam filters!
So the myth is busted, the DNA filters can successfully be used in any environment, on and off the road, in the desert or the outback, DNA will be there to protect you.
Here comes increased torque & power.
The DNA filter will also smoothen out the air flow stream, as it passes through the filter, reducing turbulence and sending smooth clean & fresh air towards the engine intake, increasing torque and power. Additionally to the high air flow, smooth and unified air flow is very important. This explains why we see a decrease in the power output when testing a bike or car on the dyno "without" a filter as the circulation of the air in the air box is disturbed and the result is turbulence and low power output.
FAQs About DNA Air Filters
Does the DNA filter provide the same level of protection as the OEM filter?
Yes and even better, the DNA filters have a filtering efficiency of minimum 98% (ISO 5011 test). Good quality OEM paper filters are from 97% to 99% and the foam filters are from 92% to 97%.
What is filtering efficiency?
Filtering efficiency is the amount of "dirt" the filter can maintain (stop) and protect the engine efficiently. For example, the DNA Filter for every 100 grams of dirt that it will receive, it will "trap" 98-99 grams, and this applies even to fine dirt as small as 5 microns.
What is ISO 5011 filtering efficiency test?
The percentage of dust that the filter retains during a laboratory test, following the ISO 5011 protocol.
How does DNA measure the airflow and why is this data useful for me, the end user?
DNA uses the most advanced computerized ROTRONICS flowbench available today. The complete procedure is computer controlled/automated, to avoid human error. Additionally, wa always test the DNA filters back to back, the same day and time, with the stock OEM filters and publish the results. Reading our data, you can immediately see the differences in air flow, between the 2 filters and what to expect by using the DNA filters.
Other performance filters manufacturers, claim air flow data much higher than DNA for the same model, is it possible? I also tried to find the stock OEM filter flow data from them to compare.Can i use the DNA Data?
It was brought to our attention, so we purchased the filters and tested them back to back at the same set pressure, with our DNA and the stock OEM filters. Well guess what, the data claimed were false, nothing to do with the reality! Of course the flow was higher than the stock but much lower compared to the DNA! No wonder they never compare it with the stock, as they can't claim 300% (!) increase in air flow over the stock OEM filter. Only data measured back to back the same time are comparable, don't forget we are measuring air! This is why we always publish the stock OEM data.
Can I change my OEM filter with a DNA without changing fueling?
In cases the air flow of the DNA Filter is extremely high we include with the filter special instructions.
I have heard that only the foam filters are good for Off-Road use not the cotton ones. Can I use the DNA filter for Off-Road use?
DNA has developed a unique filtering media that is perfect for off-road use. During the toughest rally in the world, DAKAR 2011 in Argentina - Chile, one of the factory Aprilia 450 Rally bikes, was racing with DNA filter. The results were very impressive compared to the rest of the team's bikes racing with foam filters. Every evening when the bikes were serviced, compared back to back the DNA filter and the foam filters, absolutely no dust had passed through and the engine was like new! Not to mention that one filter was enough for each day, compared to 2 or 3 foam filters per day the other bikes had to use. So this myth is busted!
Can I use the DNA filter un-oiled? Must I always apply oil after cleaning it?
No, you must never use the DNA filter un-oiled. The oil is a crucial part of the filtering media. You must always apply the Special DNA filter oil, not just any oil, after servicing the filter.
Absolutely no, DNA uses very special thixotropic polyurethane that will not leak in the filtering media reducing the active filtering area, when we produce our round filters. Concerning the panel filters, we will allow a controlled 3 to 5 mm leak, that is nothing compared to the uneven 10 to 15 mm leak that our competitors have.
I have a race bike. Do I need to use a filter and if yes why DNA?
Race bikes must be kept always in top condition, especially the engine. Debris and flying bugs found at the track, plus rubber from the bikes' tires in front, can seriously damage the engine. DNA will provide the maximum air flow and at the same time maximum protection. We do not compromise filtering efficiency in order to increase flow; we increase air flow using our revolutionary FCd design, maintaining the 4 layer reliable DNA filtering media. If you want the highest air flow and filtering efficiency of 98% for your race engine, then your only choice is DNA.
The DNA FCd design is an innovation by DNA. It allows the pleated filtering media to follow precisely the air box contour, regardless the complexity of the shape. Using the complete footprint of the air box, we eliminate "dead spots" that rob power and at the same time seriously increase air flow. Using DNA FCd technology, at least 20% and up to 80% more filtration area is common!
How often do I have to clean my DNA filter?
The servicing intervals depend on the environment that the vehicle is used. Once a year or every 15.000 to 30.000 km is suggested, to keep your DNA filter in top condition. An easy way to check if the filter needs cleaning, is to see if the wire mesh that that is on the dirty side, is visible.
If you can see the mesh, you can continue using the filter. If the mesh is totally covered in debris, you must clean the filter.
Can I use gasoline, thinners or compressed air to clean my DNA filter?
Absolutely no! You must treat your DNA filter as delicate textile. How woulld you clean an expensive and delicate garment? First of all read the cleaning instructions, then follow them carefully. Every DNA filter packaging & the DNA service products include detailed cleaning instructions. The procedure is very user friendly.
