1.What is an air filter?
Air filter is equivalent to a human mask and is the first “level” for air to enter the engine. The main function is to filter out the sand and some suspended particles and other impurities (sand, dust, colloid, alumina, iron oxide, etc.) in the air that will enter the cylinder, so as to reduce the wear and tear of the cylinder, piston, piston ring, valve and valve seat. Early wear to keep the engine working properly. Also protects the air flow meter and turbo boost.The air filter is the mask of the engine. Its main function is to filter dust and other impurities in the air that is about to enter the cylinder, so as to reduce early wear of the cylinder, piston, piston ring, valve and valve seat, so that the engine can work normally.
2.How does the work?
The air filter element in the air filter is usually made of fiber, foam, carbon and other materials. When the air enters the filter from the intake pipe, the fiber, foam and other materials of the filter will filter out foreign matter and other substances in the air. Impurities and carbon will absorb harmful gases in the air. But if the air filter is used for a long time, its filtration effect will also decrease. In other words, the air filter element is actually a consumable item~
3.Why choose Arrow air filter？https://youtu.be/7M48s2NZ-6w?si=XtNn3mb-pTFX_V_h
Air filter paper used by Arrow is wood pulp fully glued paper. Features: a. High waterproof performance; b. High stiffness performance; c. High filtration precision performance; d. High air permeability performance; e. High dust holding performance. Arrow’s wood pulp fully gummed paper has evenly distributed wood pulp fibers to ensure Its porosity is high, which is generally understood to ensure both optimal air permeability and maximum filtration accuracy.
The following content is a professional introduction:
a. The wood pulp cellulose used in this product consists of block conifer pulp and mercerized pulp. Wood pulp can be divided into softwood pulp and broadleaf pulp. Compared with broadleaf pulp, softleaf pulp has the advantages of high strength and high air permeability. The filter paper produced has high strength, high air permeability and good stiffness.
The block coniferous pulp used in the filter paper used by Arrow has the characteristics of higher bulk, higher porosity, higher dust holding capacity and smaller pore size than the filter paper produced by conventional flake coniferous pulp. The mercerized pulp used in filter paper is a reprocessed product of ordinary coniferous pulp. Its unique high air permeability, high dust holding capacity and other characteristics are far beyond the reach of ordinary pulp, so it is very expensive.
b.The wood pulp cellulose in this product consists of block conifer pulp and mercerized pulp. Softwood pulp, compared to broadleaf pulp, offers higher strength and air permeability. The block conifer pulp used provides higher bulk, porosity, dust holding capacity, and smaller pore size than conventional pulp. The expensive mercerized pulp has exceptional air permeability and dust holding capacity, surpassing ordinary pulp.
5.When should the air filter be replaced?
We usually try to drive on roads with better environmental conditions and avoid sandy roads. Secondly, the air filter needs to be checked and replaced regularly to ensure its filtration effect. If the filter element is aged and damaged, it must be replaced in time. It is generally recommended to replace it every 1 hour of driving and every 10,000 kilometers or about half a year. Finally, we also need to choose the appropriate air filter according to the different use environments of the vehicle.
