The Anatomy of a DNA High Performance Filter

This is what Power is made of!

A DNA High Performance Filter is a high quality, next generation multilayer cotton gauze,flameproof, oil impregnated air filter.

1. The DNA Cotton

This very special cotton is designed by DNA's R&D engineers for High Performance filtering purposes. The basic media is a non woven surgical cotton gauze with a modified TEX & THREAD, with extremely high strength of break. This unique cotton media, actually is a "hairy hybrid" featuring extremely high air flow rates and excellent filtering efficiency that exceeds 98%.

2. The DNA Wire Mesh

The DNA wire mesh, is a very special material designed by DNA's R&D engineers. Made out of marine grade 5000 series Aluminum, features a unique "wrap & fill" and precisely calculated wire diameter, to have the necessary high tensile strength and elasticity to last a lifetime. Additionaly it is protected against oxidation by a fine layer of epoxy coating. The DNA wire mesh is designed to perfectly support the cotton layers and at the same time not restrict the air flow.

3. The DNA Filtering Media

The DNA Filtering Media consists of 4 layers of DNA cotton, sandwiched between 2 layers of DNA wire mesh, precisely pleated all together. The filter is produced from a very wide selection of media, starting from 8 mm to 50 mm height, with an infinite size of "Pitch". Actually there is an unlimited combination of DNA Filtering Media when designing a new filter. Another important feature of the filtering media is the "Large pleat edge radius". This feature allows the edge to be an active part of the filtering media, instead of a "dead" inactive area as what some competitors have. The result is a unified high air flow of the filter. The only drawback of this design is that the media is very sensitive during production before molding and must be handled with extreme care, increasing the production cost.

4. The DNA Filter Oil

This is an extremely important part of the DNA filter. As soon as the DNA Oil is added to the cotton media, the cotton is "static charged" and transformed into an unbeatable filtering material! To achieve this fantastic result DNA have developed a unique air filter oil formula. The specifications of the DNA Air Filter Oil are as impressive as the filters are. Humidity will not attack the oil, even if the filter is submersed in water. The flow of the filter remains unchanged even under extreme rainy conditions with high humidity. (Many competitors' filters transformed into a "milky mess" when it rains, severely reducing the performance of the engine). The oil has low viscosity, plus very high temperature resistance and stability. It will uniformly spread and stay on the filter regardless the temperature. Additionaly, it is UV resistant and easily soluble to assist cleaning the filter.

5. The DNA PU (elastomer polyurethane)

The DNA PU is a thixotropic material, that we use to manufacture the high quality "frame" of the filter, with unique material specifications. High tensile strength with the necessary hardness for each application, high temperature, fuel and oil resistance, the DNA PU will keep the filtering media in place, it will absorb vibration and will last for a life-time.

6. The DNA EVA (Ethylene Vinyl Acetate polymer) closed cell seals

 Only high quality EVA seals are used. Precisely cut and factory installed (glued) using industrial grade adhesive, guaranty a perfect airtight sealing and trouble free filter installation for the user. The DNA EVA seals and the industrial adhesive are fuel, oil and temperature resistant. Additionally the DNA cleaner will not affect them when the filter is cleaned!

7. The DNA FCd design technology

The DNA FCd design or "Welcome to the Future"! At least 20% and up to 80% more filtration area, using DNA FCd technology is common. The unique revolutionary design, an innovation by DNA, allows the pleated filtering media to follow precisely the air box contour, regardless the complexity of the shape, seriously increasing air flow. Taking advantage of the complete footprint of the air box, DNA eliminate "dead spots" that rob power. If the area is there why not use it!

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 the 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 It's called, 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!

The design of 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.

DNA filters have been 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.
