High-quality automotive air conditioning filter, high-end air conditioning filter OEM 1K1819653A

An air conditioning air filter is a device used to filter out impurities in the air within an air conditioning system, playing a crucial role in ensuring indoor air quality and the normal operation of the air conditioning system.
Structure and Materials
Outer Frame: Commonly made of cardboard, aluminum alloy, galvanized iron, stainless steel, etc. For example, the outer frame of a high - temperature - resistant air filter is made of stainless steel, which can withstand temperatures of 250 - 300℃.
Filter Media: There are various types, such as non - woven fabric, nylon mesh, glass fiber, activated carbon, and ultra - fine glass fiber paper. Non - woven fabric is widely used in 初效 and Medium efficiency filters due to its low cost and good filtering performance. Ultra - fine glass fiber paper is usually used in 高效 filters for its high - efficiency filtering ability.
Classification and Function
(Pre - filter): Suitable for the primary filtration of air conditioning systems, mainly used to filter dust particles larger than 5μm. It has three styles: plate - type, folded - type, and bag - type. It is often used for the pre - filtration of central air conditioning and centralized ventilation systems, large - scale air compressors, and clean air return systems.
(Medium - efficiency filter): Mainly used in central air conditioning and centralized air supply systems to capture dust particles and various suspended substances with a particle size of 1 - 5μm. It can protect the lower - level filters and the system itself. The common structures are bag - type and non - bag - type (including plate - type, partition - type, and combined - type).
(High - efficiency filter): Mainly used in industries such as microelectronics, precision instruments, and healthcare, as well as in various clean rooms and purification equipment for the final - stage air filtration. It can capture fine particles with a particle size of 0.1 - 0.5μm, and the filtration efficiency can reach over 99.999% (at 0.3μm, DOP method).Performance Parameters
Filtration Efficiency: It refers to the ratio of the amount of dust captured by the filter to the original dust content in the air. Different types of filters have different filtration efficiencies. For example, the filtration efficiency of 初效 filters is relatively low, usually in the range of G1 - G4; the filtration efficiency of 中效 filters is 60% - 95% (colorimetry method); and the filtration efficiency of efficient filters is extremely high.
Initial Resistance and Final Resistance: The resistance of a new filter is called the "initial resistance", and the resistance value corresponding to the filter's scrapping is called the "final resistance". Generally, the final resistance of a filter in use is 2 - 4 times the initial resistance.Rated Air Volume: It is the maximum air volume that the filter can pass through, which depends on the size of the filter and the area of the filter media.
Importance of Maintenance
Energy Efficiency: A dirty or clogged air filter can restrict airflow, causing the air conditioning system to consume more electricity to maintain the set temperature. Replacing a dirty filter can increase the system's efficiency by 5 - 15%.
Comfort: A clean filter ensures that the air conditioning system can stably provide comfortable air, while a dirty filter may lead to uneven air supply and reduced cooling or heating effects.
System Reliability: Regularly replacing the filter can reduce the workload of fan motors and other components, thereby extending the service life of the air conditioning system.
