Something You Should Know about Air Filter

An air filter is a device that purifies the air. If the dust, sand and various impurities in the air directly enter the engine cylinder and burn, they will accelerate the wear of the engine, thereby reducing the service life of the engine and even causing serious damage to the engine. In short, the air filter protects the engine. As one of leading air filter making machine manufacturers, we will introduce it to you in detail.

The role of the air filter

• Interception: The dust entering the filter medium will hit the medium many times, and it will be stuck when it hits the medium. The dust particles in the air will move with the airflow through inertial motion, random motion or some kind of field force. The particle motion hits other objects, causing the particles to stick to the surface of the fiber;

• Electrostatic effect: Static electricity makes the dust change its trajectory and hit obstacles. Static electricity makes the dust stick more firmly on the medium. Fibers and particles may be charged, resulting in electrostatic effects. The filtering effect of electrostatic filter materials can be significantly improved;

• Filtration material: The air filter is to filter solid substances in the air, such as iron filings or sand particles, etc. The function of the air filter is to separate the liquid water and liquid oil droplets in the compressed air, and filter the air. dust and solid impurities, but cannot remove gaseous water and oil.

How to choose a car air filter?

Paper conventional air filter

Paper air filter is currently the most widely used product, which can filter out dust and debris in the air while ensuring that the engine gets a sufficient amount of air supply during operation.

The paper air filter has a price advantage, and the low development and manufacturing costs also make suppliers more willing to enrich the product line to adapt to more models. However, paper air filters also have certain limitations in certain application environments, one of which is that they are not suitable for commercial vehicles.

In addition, if the air pollution in the vehicle location is serious, the speed of air filter pollution will be accelerated. Paper air filters cannot be cleaned and reused, so they are replaced more frequently in harsh environments, which in turn increases vehicle maintenance costs.

Fiber mesh air filter

The fiber mesh type air filter can be reused after cleaning. Such products can play a greater value in the hands of practical users who can independently complete the air filter disassembly and replacement operations.

The fiber mesh type air filter can be divided into oil-immersed mesh and dry synthetic fiber according to the use environment. The most important feature of this type of product is that it can be cleaned and used repeatedly. Although the price of fiber mesh type air filter is twice that of paper air filter, if the expenses saved by not requiring frequent replacement in subsequent use are counted, this type of air filter has special advantages in terms of cost saving.

But there is a premise to save this money, that is, the owner can disassemble, clean the air filter, and refill the oil-immersed air filter by himself.

Sponge-coated air filter

In the internal combustion engine industry, foam sponges are used to make air filters for micro-engines, used in ATVs and lawn mowers. Car engines rarely use pure sponge air filters, but some car air filters will cover the outermost layer with sponge for additional protection.

The sponge used for engine air filter has undergone special oil soaking treatment, which can absorb dust particles and debris in the air more efficiently. This is just enough to meet the work needs of ATVs, lawnmowers and other equipment. However, the air filter made of sponge has the disadvantage of small airflow, which reduces the power output of the engine. Those driving in wind-sand-prone areas can replace the air filter with a sponge layer, which can better prevent dust and debris from invading the engine interior.
