Structural characteristics：

Its appearance resembles the bellows of an accordion, consisting of multiple layers of folded filter paper. The filter paper is usually made of high-quality fiber material with fine pore size. This folding design greatly increases the filtration area, achieving efficient filtration in a limited space. Compared to traditional flat filter paper, the effective filtration area of organ paper filters can be expanded several times under the same volume. The filter paper is usually equipped with sturdy metal or plastic frames on both sides to support the filter paper structure, ensuring that the filter paper can remain flat and not deform under certain pressure, ensuring the stability of the filtering effect.

Working principle：

Based on the principle of deep filtration, when air or liquid containing impurities passes through an accordion paper filter, the impurity particles are intercepted on the surface or in the fiber gaps inside the filter paper due to their larger particle size than the filter paper aperture. Filter paper fibers have a certain electrostatic adsorption capacity, which can capture some small charged particles and further enhance the filtration effect. For air filtration, it can effectively remove small particles such as dust, pollen, smoke, etc; In terms of liquid filtration, such as lubricating oil, fuel, and hydraulic oil filtration systems, impurities such as metal debris, gum, and moisture can be intercepted to ensure the purity of the liquid and maintain the normal operation of the equipment.

application area：

Industrial manufacturing: used in factories such as automobile manufacturing, mechanical processing, and electronic chip production to purify workshop air, prevent dust particles from contaminating products, and ensure product quality. For example, in an automobile engine assembly workshop, if too much dust enters the engine interior, it can cause component wear and affect engine performance and service life. Organ paper filters can provide clean air to ensure production. At the same time, fine filtration of oil is carried out in the equipment lubrication system and hydraulic system to reduce the occurrence rate of equipment failures.

The medical industry: hospital operating rooms, sterile wards, pharmaceutical workshops and other places have extremely high requirements for air quality. Organ paper filters can remove dust particles attached to bacteria and viruses in the air, create a sterile environment, reduce patient risks, and ensure that drug production meets strict quality standards.

Commercial office and home: Installing organ paper filters in the central air conditioning and ventilation systems of office buildings and shopping malls can improve indoor air quality and create a comfortable and healthy working and shopping environment for people; Some household air purifiers also use organ paper filters to efficiently purify indoor air, remove pollutants such as haze and formaldehyde, and care for the respiratory health of family members.

advantage：

High filtration efficiency: With its unique folding structure and fine filter paper material, it has extremely high interception efficiency for small particles, which can meet various precision filtration needs. Some high-quality organ paper filters can achieve a removal rate of over 99% for particles with a diameter of 0.3 microns or even smaller.

Long lifespan: Under normal usage conditions, due to the large dust holding capacity and stable structure of the filter paper, the replacement cycle is longer compared to ordinary filter paper filters, reducing the cost and maintenance workload caused by frequent filter replacement.

Low resistance:

Although the filtration accuracy is high, the reasonable folding design reduces the resistance of airflow or liquid flow passing through, ensuring the filtration effect without causing excessive pressure loss to the system operation, which helps the equipment operate in an energy-saving manner.

Key selection points：

Filtering accuracy: Choose the appropriate aperture filter paper according to the specific application scenario requirements. For example, electronic chip manufacturing requires high accuracy, while general ventilation systems require relatively lower accuracy.

Flow requirements: Consider the flow rate of air or liquid in the system to ensure stable operation of the filter at rated flow without blockage or insufficient flow. When selecting, refer to the flow parameters provided by the filter manufacturer.

Size adaptation:

Based on the size of the installation space, select an organ paper filter with appropriate external dimensions to ensure smooth installation and effective connection with upstream and downstream equipment, achieving system integration.

Material compatibility: When filtering liquids, special attention should be paid to the chemical compatibility between the filter paper and frame materials and the filtered liquid to prevent chemical reactions such as corrosion and dissolution, which may affect the performance and service life of the filter.
