The initial folding air filter is a device used for air filtration, mainly applied in the primary filtration process of air conditioning systems, ventilation systems, etc. Its appearance presents a folding structure, which allows the filter to have a larger filtering area in a limited space, and can more effectively capture dust particles, dust, and various suspended solids in the air. The outer frame materials are diverse, including paper frames, aluminum frames, galvanized iron frames, stainless steel frames, etc., which can be selected according to different usage environments and needs.

Primary folding air filterDesign Features：

Unique folding structure：

The folding design of the initial folding air filter is one of its advantages. Compared with traditional flat filters, the folding structure * * increases the contact area between the filter material and the air, improving the filtration efficiency. At the same time, this structure also allows the filter to reduce volume, facilitate installation and replacement while maintaining high filtration performance.

Durable outer frame design：

The outer frame is an important component of the primary folding air filter, which plays a role in fixing the filter material. Generally, it is made of sturdy waterproof boards or materials with high hardness, such as cardboard frames, aluminum profiles, etc. The diagonal design on the outer frame can provide a larger filtering area and tightly adhere the internal filter material to the outer frame, ensuring the stability and reliability of the filter.

natureExcellent protective net:

In order to protect the filter material from being blown out, primary folding air filters are usually equipped with protective nets such as welded wire mesh or galvanized iron mesh. These protective nets have undergone surface rust prevention treatment, which not only effectively fixes the filter material, but also prevents deformation caused by excessive wind pressure, ensuring that all filter material surfaces can be fully utilized.

Multiple filtration efficiencies to choose from：

According to different filtration requirements, the primary folding air filter offers multiple filtration efficiency levels, such as G1, G2, G3, G4, etc. (compliant with EN779 standard). Users can choose the appropriate filtering efficiency level based on actual application scenarios to achieve better filtering results.

Performance advantages

High air volume and low resistance：

Thanks to its unique folding structure and optimized design, the primary folding air filter has the characteristics of high air volume and low resistance. While ensuring smooth air circulation, it can effectively block impurities in the air and reduce the level of air pollution. Even after prolonged use, the resistance of the filter increases slowly, reducing energy waste caused by excessive filter resistance.

High dust holding capacity：

The filter material of the initial folding air filter adopts special materials and processes, which have a high dust holding capacity. This means that the filter can accommodate more dust and impurities, extending its lifespan, reducing replacement frequency, and lowering usage costs.

Easy to maintain：

The maintenance of the initial folding air filter is very simple and convenient. When the filtration efficiency of the filter decreases or the resistance increases, simply remove it from the equipment, clean or replace it. For paper frame filters, they can be incinerated after use, without pollution, and meet environmental protection requirements.

Primary folding air filterApplication areas:

Central air conditioning and ventilation systemThis is one of the main application areas of primary folding air filters. In central air conditioning and centralized ventilation systems, the primary folding air filter can perform primary filtration on the air entering the system, removing large particles of dust, hair, fibers and other impurities from the air, protecting subsequent medium and high-efficiency filters, and extending the service life of the entire system.

Pre filtration of large air compressorsA large air compressor needs to inhale a large amount of air during operation. If the air contains impurities, it will have a serious impact on the performance and service life of the air compressor. The initial folding air filter can effectively filter impurities in the air, provide clean air for the air compressor, and ensure its normal operation.

Cleanroom and Electronic BuildingIn places with high air quality requirements such as clean rooms and electronic factories, the primary folding air filter serves as the pre filtration defense line of the air purification system, which can remove most impurities in the air and provide a good foundation for subsequent efficient filtration, ensuring that the cleanliness of indoor air meets the requirements.

civil architectureIn the ventilation and air conditioning systems of large civil buildings such as office buildings, shopping malls, hospitals, sports centers, and airports, primary folding air filters have also been widely used. It can provide people with a comfortable and healthy indoor environment while reducing the energy consumption of air conditioning systems.
