Product Description

The introduction of air filter
During the operation of the engine, a large amount of air needs to be sucked in. If the air is not filtered and the suspended dust in the air is sucked into the cylinder, it will accelerate the wear of the piston group and cylinder. Large particles entering between the piston and cylinder can cause serious "cylinder pulling" phenomenon, especially in dry and sandy working environments. The air filter is installed in front of the intake pipe to filter out dust and sand particles in the air, ensuring that sufficient and clean air enters the cylinder.
The commonly used air filter types in engines include inertia oil bath air filters, paper dry air filters, polyurethane filter air filters, and so on. The inertia oil bath air filter has undergone three stages of filtration: inertia filtration, oil bath filtration, and filtration filtration. The latter two types of air filters are mainly filtered through the filter element filtration. Inertia oil bath air filters have the advantages of low intake resistance, adaptability to dusty and sandy working environments, and long service life. They were previously used in various models of cars. However, this type of air filter has low filtration efficiency, high weight, high cost, and inconvenient maintenance, and has gradually been phased out in automotive engines. The filter element of the paper dry air filter is made of resin treated microporous filter paper. The filter paper is porous, loose, folded, and has a certain mechanical strength and water resistance. It has the advantages of high filtration efficiency, simple structure, light weight, low cost, and convenient maintenance. It is the most widely used automotive air filter in the past. The polyurethane filter element of the air filter is made of soft, porous, sponge like polyurethane with strong adsorption capacity. This type of air filter has the advantages of paper dry air filters, but has low mechanical strength and is widely used in car engines. The disadvantage of the latter two types of air filters is their short service life and their unreliable operation in harsh environmental conditions.

Air conditioning filter, commonly known as pollen filter, is used to filter the air entering the interior of the car from the outside to improve the cleanliness of the air. The general filtering substance refers to impurities contained in the air, such as small particles, pollen, bacteria, industrial waste gas, and dust.
The effect of air conditioning filters is to prevent such substances from entering the air conditioning system and damaging the air conditioning system, providing a good air environment for passengers in the car, protecting the physical health of passengers in the car, and also preventing glass fogging.
Air conditioning filters are generally divided into two types: ordinary air conditioning filters and activated carbon series air conditioning filters. Ordinary air conditioning filters are generally made of a specific environmentally friendly filter material that has been processed and folded, and are mostly white single-layer. The activated carbon series air conditioning filter is made of a composite of two non-manufactured fabrics (non-woven fabrics) with small particles of activated carbon sandwiched in the middle, and further processed to produce an air conditioning filter. Car air conditioning filters are usually installed in the lower glass compartment in front of the passenger compartment of the car, and car owners can also replace them according to their own conditions, as their disassembly and operation process is very simple; It can also be replaced by store staff at the sales and maintenance 45 store of one's own car.
Ordinary air conditioning filters can only suppress the entry of dust and particulate matter. The activated carbon series air conditioning filters can utilize the physical properties of particulate activated carbon itself to adsorb other small particles and more harmful substances in the air during a short period of time when the air passes through the blockage. So for comparison, the effectiveness of the activated carbon series air conditioning filters is much better than that of ordinary filters. The replacement time and cycle of the air conditioning filter are generally when the car is driving 8000 to 10000 kilometers, and can also be determined based on the external environment of the driving. If the environment has a high dry and humidity ratio, the climate is dry all year round, and the wind and sand are strong, it should be replaced in advance.
