INTRODUCTION

The stainless steel filter materials are made of high-quality stainless steel materials, such as 304 and 316 stainless steel. Through precise pleating processes, the main body of the filter cartridge with numerous folds is formed, which greatly increases the filtration area. The support net provides stable support for the filter materials, ensuring that they will not be easily deformed when subjected to fluid pressure and guaranteeing the stable progress of the filtration process. The end caps usually adopt metal materials that match stainless steel well and are connected by welding and other firm connection methods to achieve good sealing effects and facilitate connection and installation with various filtration devices. Thanks to their sturdy and durable characteristics and excellent filtration performance, these filter cartridges are widely used in the filtration systems of many industries with high requirements for filtration precision and stability, and there are diverse specifications available for selection according to needs.

WORKING PRINCIPLE

Stainless steel pleated filter cartridges achieve the filtration function based on the principle of physical interception. When fluids (liquids or gases) containing impurities flow through the filter cartridges, driven by the pressure difference, the fluids enter the interior of the cartridges. Since the filter materials have a large number of fine and evenly distributed pores after being pleated, impurity particles with particle sizes larger than these pore sizes cannot pass through smoothly and will be intercepted on the surface of the filter materials. Meanwhile, substances with particle sizes smaller than the pore sizes, such as water molecules and small gas molecules, can pass through the filter cartridges along the pores, thus separating the impurities in the fluids and achieving the purpose of fluid purification. Moreover, their large filtration area makes the filtration process more efficient, enabling them to handle a large amount of fluid in a short time and meet the filtration needs of different scales.

PRODUCT FEATURES

l High Filtration Precision: By precisely controlling the pore size of the filter materials and the pleating process, high-precision filtration from the micron level to the sub-micron level can be achieved. It can effectively intercept tiny particles, suspended substances, bacteria and other impurities, and is especially suitable for industries with strict requirements for fluid purity, such as the preparation of ultrapure water in the electronics industry and sterilization filtration in the pharmaceutical industry.

l High Strength and Durability: Made of stainless steel materials, it has excellent mechanical strength and can withstand relatively high working pressures without being easily damaged or deformed. Even in complex and harsh working condition environments, such as those with high temperature, high pressure, and strong corrosive fluid environments, it can still work stably for a long time, has a long service life, and reduces the costs and operational burdens caused by frequent replacement of filter cartridges.

l Good Chemical Stability: Stainless steel itself has good tolerance to a variety of chemical substances. Whether it is acidic, alkaline or organic solvent fluids with different chemical properties, it can carry out normal filtration work, has a wide range of applications, and can be applied to the filtration needs of multiple industries under different chemical environments, such as the chemical industry, food and beverage industry, and environmental protection industry.

l Strong Dirt-Holding Capacity: The pleated structure of the filter materials enables it to have a large filtration area within a limited space. This not only improves the filtration efficiency but also means that it can accommodate more impurities, has excellent dirt-holding capacity, can maintain good filtration effects for a long time, and further reduces the use cost.

l Easy to Clean and Reusable: The characteristics of stainless steel materials determine that it is easy to clean. When the filter cartridges are clogged after a period of use, impurities on the surface of the filter materials can be removed by appropriate cleaning methods, such as chemical cleaning and ultrasonic cleaning, to restore their filtration performance and achieve multiple reuses, improving the economy of the filter cartridges.

APPLICATION FIELDS

l Pharmaceutical Industry: The pharmaceutical production process has extremely high requirements for the purity of water, air, etc. Stainless steel pleated filter cartridges play an important role in the filtration of water used for drug preparation, the pretreatment of injection water, and the filtration of air in clean workshops. They can accurately remove bacteria, particles in water and dust in the air, ensuring that they meet the strict requirements of the Good Manufacturing Practice (GMP) for pharmaceutical production, safeguarding drug quality and medical safety.

l Electronics Industry: In processes such as electronic chip manufacturing and liquid crystal panel production, the purity requirements for water and gas in the production environment are extremely strict. Stainless steel pleated filter cartridges, relying on their high filtration precision and excellent stability, can intercept tiny particles, organic substances and other impurities in water and particles in gas, providing ultrapure water and a clean gas environment for the electronics industry, avoiding adverse effects of impurities on the performance of electronic components, and ensuring the high quality and stability of electronic products.

l Chemical Industry: Chemical production involves numerous complex chemical reactions and fluid treatments. Stainless steel pleated filter cartridges can be used for the filtration of various chemical raw materials, intermediates and finished products to remove solid impurities, suspended substances, etc., ensuring the smooth progress of reactions and the quality of products. Meanwhile, their chemical stability enables them to adapt to the filtration needs under different chemical environments such as different acid-base levels and organic solvents, helping to achieve efficient and stable chemical production.

l Food and Beverage Industry: In processes such as raw water filtration in beverage production, purification of water used for ingredients, and filtration of cleaning water in food processing, stainless steel pleated filter cartridges are indispensable. They can effectively remove impurities in water that may affect taste, quality and hygiene and safety, ensuring that the produced food and beverage products meet relevant hygiene standards and taste requirements, maintaining the brand image of enterprises and safeguarding the health of consumers.

l Environmental Protection Field: Stainless steel pleated filter cartridges also play an important role in sewage treatment and waste gas treatment. For example, in sewage treatment, they can perform fine filtration on preliminarily treated sewage to further remove tiny pollutants in water and improve water quality. In waste gas treatment, they can filter particulate matter in waste gas to reduce pollution to the atmospheric environment and contribute to environmental protection.

SUMMARY

Stainless steel pleated filter cartridges, with their unique structures, reliable filtration principles, numerous excellent characteristics, and reasonable technical parameters, have demonstrated irreplaceable value in many key fields such as the pharmaceutical industry, electronics industry, chemical industry, food and beverage industry, and environmental protection industry. They are like the sturdy guardians in the filtration field, quietly contributing to ensuring the purity of fluids required by various industries, improving product quality, and promoting the sustainable development of various industries. With the continuous progress of science and technology, it is believed that stainless steel pleated filter cartridges will continue to make breakthroughs in aspects such as improving filtration precision, optimizing performance, and expanding applications, further meeting the increasingly diverse filtration needs of society and becoming one of the core supporting equipment for creating a high-quality production and living environment.
