INTRODUCTION

The filter membrane, as the core component, is manufactured using advanced techniques to create a large number of evenly distributed micropores, which are the key to achieving precise filtration. The supporting structure firmly stabilizes the filter membrane, enabling it to remain stable when facing fluid pressure and ensuring the smooth progress of the filtration work. The end caps usually adopt plastic materials with good compatibility and excellent sealing properties, facilitating connection with various filtration devices. Its unique pleated structure greatly expands the filtration area, achieving efficient filtration within a limited space. Moreover, it comes in a wide variety of specifications and can be flexibly selected according to specific requirements such as flow rate and precision in different filtration scenarios, and is widely used in the filtration systems of numerous industries.

WORKING PRINCIPLE

PP microporous pleated filter cartridges rely on the physical sieving mechanism to achieve the purpose of filtration. When fluids (liquids or gases) containing impurities flow through the filter cartridges under the action of pressure difference, the fluids enter the interior of the cartridges. Due to the densely distributed micropores on the filter membrane, impurity particles with particle sizes larger than the pore diameters of the micropores will be intercepted on the surface of the filter membrane, while substances with particle sizes smaller than the micropore diameters, such as water molecules and small gas molecules, can smoothly pass through the micropores. In this way, the impurities in the fluids are effectively separated, achieving the purification of the fluids. Moreover, the large area of the filter membrane enables this physical sieving to occur simultaneously over a large range, thus quickly and efficiently completing the filtration process.

PRODUCT FEATURES

l High Filtration Precision: It can precisely control the filtration precision within the range of 1 - 60 µm. Whether it is tiny particles, suspended substances, or various bacteria and other impurities, they can all be effectively intercepted. It performs excellently in scenarios with strict precision requirements, such as the preparation of ultrapure water in the electronics industry and the sterilization filtration in the pharmaceutical industry, effectively ensuring the purity of the filtered fluids.

l Excellent Filtration Efficiency: The filtration efficiency is as high as over 99%, which means that the vast majority of impurities can be effectively removed, greatly improving the purity of the fluids and providing high-quality fluid guarantees for the production processes of various industries, helping to improve product quality.

l Low Filtration Resistance and High Flow Rate: Thanks to its ingenious structural design, the resistance when fluids pass through is small, and at the same time, a relatively large filtration flow rate can be ensured. This ensures that while meeting the filtration requirements, it will not cause excessive pressure loss to the entire fluid delivery system, ensuring the efficient operation of the system.

l Strong Dirt-Holding Capacity and Long Service Life: The fiber diameter and gap can be adjusted flexibly, and the micropores have the characteristic of being smaller on the inner layer and larger on the outer layer. This unique structure not only increases the flow rate but also significantly improves the dirt-holding capacity. It can accommodate impurities for a long time, delay the clogging of the filter cartridges, and effectively extend the service life of the filter cartridges, reducing the costs and operational burdens caused by frequent replacement of filter cartridges.

l High Self-Cleanliness: It has a high degree of self-cleanliness and will not cause additional pollution to water or other fluids during the filtration process, meeting the high-standard requirements of industries with extremely high purity requirements, especially applicable to industries such as food and pharmaceuticals.

l Superior Strength Performance: It has strong strength. Even when the pressure difference between the inlet and outlet exceeds 0.4 MPa, the filter cartridges will not deform. Moreover, when the temperature exceeds 90 °C, the filtration efficiency will still not decrease, enabling it to work stably and reliably under relatively harsh working conditions and adapt to various complex application environments.

l Good Sterilization Tolerance: It can withstand online steam sterilization at 126 °C for 30 minutes. This characteristic enables it to conveniently conduct regular sterilization operations when used in industries with strict hygiene requirements such as pharmaceuticals and food, ensuring that the filtration system remains in a sterile state at all times, safeguarding product quality and usage safety.
