Basic knowledge about air filters
Abstract: When the piston machine is working, if the inhaled air contains dust and other impurities, it will aggravate the wear of the parts, so it is very important to install an air filter.
When the piston type machinery is working, if the inhaled air contains dust and other impurities, it will aggravate the wear of the parts, so it is very important to install an air filter.
What is the role of the air filter
Although the air filter is a very inconspicuous component in the car device, in the actual use of the car, the air filter has a great influence on the service life of the car, especially in the engine.
On the one hand, if there is no filtering effect of the air filter, the engine will inhale a large amount of air containing dust and particles, causing serious wear of the engine cylinder.
On the other hand, if it is not maintained for a long time during use, the filter element of the air filter will be filled with dust in the air, which will not only reduce the filtering capacity, but also hinder the circulation of air, resulting in mixed air Excessive concentration makes the engine work abnormally.

Classification of air filters
Air filters generally have two types: paper and oil bath. The filtration efficiency of the paper filter element is as high as 99.5%, while the filtration efficiency of the oil bath filter is 95%-96% under normal conditions. At present, paper air filters have a relatively high penetration rate, because they have a series of advantages such as light weight and low cost.

Filter element classification of air filter
The filter element of the air cleaner is divided into two types: dry filter element and wet filter element.
The material of the dry filter element is filter paper or non-woven fabric. In order to increase the air passage area, most of the filter elements are processed with many small folds. When the filter element is slightly fouled, it can be blown off with compressed air. When the filter element is seriously fouled, it should be replaced with a new one in time.
The material of the wet filter element is a sponge-like polyurethane material. When installing it, add some engine oil and knead it by hand to absorb foreign matter in the air. If the filter element is stained, it can be cleaned with cleaning oil, and the filter element should be replaced with a new one if it is excessively stained.

Filtration requirements for air filters
1. High filtration accuracy, able to filter out all larger particles.
2. High filtration efficiency, which can reduce the number of particles passing through the filter.
3. The low pressure difference ensures that the engine has the best air-fuel ratio.
4. Large filtering area, high ash holding capacity and long service life.
5. Small installation space and compact structure.
6. The wet stiffness is high to prevent the filter element from being collapsed.
7. No metal structure, good for environmental protection, reusable, good for storage.
