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. We produce a very wide selection of media, starting from 8 mm to 50 mm height, with an infinite size of "Pitch". Actually we can choose from an unlimited combination of DNA Filtering Media when designing a new filter. Another important feature of our 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 our competitors is. 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 we have developed a unique air filter oil formula. The specifications of our DNA Air Filter Oil are as impressive as our 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. (We have seen 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
We use only high quality EVA seals. 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, we eliminate "dead spots" that rob power. If the area is there why not use it!
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.
