Auckland Peter Legg. Auckland How and Why Does
the Green Filter© Work? Green Filter©s are made from cotton, and are described as being the best use cotton since the invention of Jeans by Levi Strauss. A standard paper filter tends to absorb moisture and dirt rather than hold onto it. With our high humidity in New Zealand there tends to be a paper machet effect produced. A Green Filter© is made from cotton, which has perfect features for air filtration. It is organic, and dries quickly after becoming damp. This allows the filter to breath easily. The 2 layers of woven cotton in the filter are pleated, allowing a 10% -20% increase in surface area for the draw down of air into the engine. The more surface area you have, the more air you can pass through the filter and into your engine to create more power. This pleating also gives the filter element extra strength and rigidity. There are 3 main benefits to using woven cotton.
The layers of cotton are held in place by a strong fine mesh that trap and hold dirt and moisture particles to a size of .050 microns. These dirty particles can easily be seen against the bright Green Filter©, indicating that it is time to clean the filter. Green High Performance Air Filters are a lifetime filter, designed to be oiled. The oil creates a positive [+] magnetic charge with the mesh, which attracts the negatively charged [-] dust particles. The dust and dirt builds around the mesh to form a tunnel. This allows the cotton to remain cleaner for maximum flow. Green High Performance Air Filters are designed with advanced, leading edge rubber moulding technology. The rubber fanges are precisely machined to offer snug, airtight seals, that absorb vibration and are not affected by the harsh conditions of the engine bay. Most other cotton air filters are manufactured by a pressure moulding injection method. This consumes filter surface area, and leads to a reduction in surface area of up to 25%. Green Filter© uses a Four Step manufacturing process that is more expensive and time consuming, but produces a filter with substantially improved airflow. Credentials Green Filter© was developed in Europe in 1995 to design, manufacture and supply premium high performance cotton air filters to the racing and motor sport industry. They have now become Europe’s largest performance air filter manufacturer. After designing filters for these sectors they have since used the exact, same technology for use on our cars, but only after thousands of tests and numerous success on race tracks around the world. Green Filter© have won awards for nearly every type of competition, here are just a few:-
Since 2000 the prestigious EAQF manufacturing Standard was awarded to Green Cotton Air Filter for their consistently high quality manufacturing standard. Green Filter© is now installed in New Zealand by our leading Race and Rally Car preparers. How Do I Order?
