Air intake is very important for cars, but how to achieve high filtration while maintaining AG air volume?
To some extent, you can believe in science.
The intuitive feeling of replacing SF high-flow air filter is that when you step on the accelerator deeply, you can clearly hear the sound of sususu.
Breathe smoothly!
Honda Civil Type R FL5SF air filter (HJS head section)
Born in 1952SPRINTFILTER is an excellent brand of high-performance air filter and special air intake products in the world, which is currently used for all kinds of high-performance RV and high-performance motorcycle and similar.WTCR and MOTO GPAir filter brand supplier.
After more than 50 years of service for racing/motorcycle racing, it finally started to be a civilian market.
The power of science and technology is powerful!
The ultimate goal of air intake is to maximize the air intake, but for the sake of engine life, it needs excellent filtration, especially for our civil vehicles that need "long life", so we can’t use the technology of "multi-throat direct injection", which has extremely high air requirements.
High flow rate and high filtration capacity are actually contradictory to each other. What if they are balanced?SprintFilter’s "polyester material"Air filter gives the answer.
Please look at this picture carefully.
Cotton filtration is a common filtration method (although this cotton is a bit rough, the original mask has been filtered by multi-layer gauze, and the essence of ordinary air filtration has not changed).
Air filtration of cotton, because the pores are too large and the pore size is not fixed, needs to rely on multi-layer stacking and weaving to improve the filtration ability, which will lead to poor airflow in some areas or may not be effective filtration.
At the beginning of use, the filtering ability of cotton air filter is low.(Only about 50% of substances in the range of 5~200 μ can be filtered), only when.The filtration capacity will increase to 80% only after the dust and impurities on the air filtration surface become thicker., but it is followed byA sharp drop in pressure.
Simply put, it is impossible to achieve a balance between high filtration and high flow.
The filtration ability of cotton air filter is low in the first half of its service life, but it will be in the rest of its service life.A high air pressure drop is equivalent to a "sharp drop in air intake", which is a troublesome problem for performance cars that need a lot of air intake.
SF’s high-flow air filtration, because of the use of "polyester fiber material", can ensure the unity of filtration network structure, ensure high filtration performance, and ensure less airflow interference-
Single-layer high-density polyester fiber can greatly reduce the turbulent flow easily generated by traditional air filtration in the past, thus ensuring that the air intake system can always operate well.
From this enlarged picture, the pores of polyester fiber are smaller than those of cotton. Under the condition of 10 times magnification, they are still smaller than those of cotton fiber with 5 times magnification, and the pore size is the same.
Ultra-high flow, higher filtration and stable performance.
This is not a random statement, but a research report from the University of Wales in the UK.
The detailed review report is shown in the link.
The research team explored the material structure of different air filters with a microscope, and we intercepted some comparative contents as examples:
The most commonly purchased and reusable, SF P08 air filter:
Monolayer polyester fiber, fixed structure
Fiber thickness: 68 μ m
Pore area: 8,184 μ m
And the edge is very clear, which is also the benefit brought by new material technology.
In the original text, some enlarged pictures of high-flow air filtration of cotton materials of other brands are involved, so we will not make subjective comparison here.
Four layers of cotton fiber, staggered weaving to improve filtration capacity.
Fiber thickness: 100 μ m
Pore area: 118,800μ m.
The edges are not clear enough.
The conclusion is that the pore size of SF P08 is one tenth or even smaller than that of common cotton, so SF can achieve good filtration effect only by using single-layer design.
To sum up:
Use technology to increase horsepower.
World brand, authentic and reliable.
Large air intake and better filtration.
Clean water, simple maintenance
Buy once and use for a long time.
At present, production vehicles are usually equipped with paper filter elements, while performance vehicles use oil-soaked cotton or sponge. The job of the air filter is to ensure good air circulation and prevent a large number of particles from entering the engine.
Therefore, the function of air filtration is to have good filtration and better air intake.
In the past, it was always thought that better air intake meant worse filtration and very troublesome maintenance, but in SF air filtration, because of the use of brand-new materials and technology, it was achieved at the same time-
The air intake is larger.
Better filterability
Maintenance is simpler
# Why is the performance so strong
SF air filter uses polyester fiber.
Compared with the poor flow caused by the multiple overlapping of cotton filter elements, the polyester fiber material of SF air filtration has high permeability and stability and is not affected by folding.
SF air filter has better filtration performance.
The ordinary four-layer oil-soaked cotton filter element made of single-layer polyester film can only filter 76.42%, while the three styles of SF air filter are more efficient:
93.13% of 100 μ particles (P08)
91.8% of 37 μ particles (P037)
95.22% of 100 μ particles (P08F1-85)
The filtration performance of SF air filter is more stable.
The construction progress of SF air filtration with steel mesh can provide stable and equal filtration effect, and the effect will not decrease with time.
Ordinary air filtration has a low filtration capacity in the initial stage (equivalent to 50% of pollutants, ranging from 5 to 200 μ). Only after the powder cake is formed on the surface, the filtration capacity increases to 80% of the above range, but it is followed by a huge pressure drop.
To sum up, cotton filters—
It has low filtration capacity within half of its service life.
However, its pressure drop is very high (gas flow rate is very low) during its remaining service life.
SPRINT FILTER engineers at Trinity St. David’s University in Wales work every day, checking product quality and researching new filtering solutions to meet the requirements of the most important racing department.
What kinds of products does # SF air filter have?
P08 (street car use, road and track)
This is the most inexpensive model. According to different models, you can buy SF high-flow filter elements that need not be replaced for life for hundreds to 1000 yuan, which can be replaced by the original factory, dried after being treated with clean water or neutral cleaning agent.
Compared with ordinary cotton filter element, it has better filtration and greater flow.
P037 (used in rally and dirty environment)
The only air filter with waterproof function in the world can not only ensure the filtering effect, but also be waterproof, and at the same time ensure the ultra-high flow of air intake, which is suitable for some competitions and dirty environments.
P08F1-85 (super high performance, waterproof, racing car, super motorcycle)
It may be the strongest high-flow filter element in the world, which can be used in racing cars, super competitions and street cars. The flow rate is 15,000 liters/m2.s, which is nearly four times that of ordinary filter elements, and it is waterproof and dustproof at the same time.
It is recommended to use all kinds of ultra-high performance cars and motorcycles.
