PES Pleated Filter Cartridges

The filter cartridge features a hydrophilic Polyethersulfone (PES) asymmetric membrane as the filtration media, combined with high-purity PP support and drainage layers.

The advanced asymmetric membrane structure provides high flow rates, low protein adsorption, excellent retention performance, and extended service life.

The filter cartridge housing, center core, and end caps are manufactured using thermal welding technology without any adhesives or surfactants, effectively reducing extractables and ensuring safe and reliable filtration performance.

All cartridges are manufactured in a cleanroom environment and undergo 100% integrity testing to ensure consistent quality, reliable performance, and compliance with demanding filtration requirements.

As membrane filtration technology continues to advance, PES microporous membrane filter cartridges have become a preferred filtration solution across a wide range of industries due to their excellent performance and reliable filtration characteristics. One of the key advantages of PES membrane filtration media is their inherent hydrophilicity and high flow rate. Unlike many other membrane materials, hydrophilic PES membranes can be rapidly wetted by water without requiring extensive pre-wetting. This allows the membrane to quickly establish a uniform filtration layer and provides efficient filtration of aqueous solutions. As a result, PES microporous membrane filter cartridges can deliver high water flow rates while improving overall filtration efficiency.

PES microporous membrane filter cartridges offer excellent chemical compatibility and thermal stability, making them suitable for demanding filtration environments. Within a broad pH range, typically around pH 1–13, PES membranes can maintain stable filtration performance and structural integrity. They also exhibit good resistance to elevated temperatures, with typical operating conditions ranging from 80°C to 120°C or higher, depending on the specific membrane grade and application.

PES membrane filter cartridges combine high mechanical strength, structural stability, and long service life. Their optimized microporous structure and high porosity provide an effective balance between filtration efficiency and mechanical performance. The membrane structure enables the filter cartridge to maintain high flow rates while withstanding pressure differentials and fluctuations in operating conditions. This helps reduce premature filter failure and supports reliable, continuous filtration in demanding industrial applications.

PES membranes have a unique low protein adsorption characteristic, resulting in extremely low loss of protein-based active materials. They are suitable for pharmaceutical processes that require high retention of active ingredients, such as injectables, biopharmaceuticals, and diagnostic reagents.

The O-type sealing design provides reliable sealing performance, effectively preventing leakage and ensuring secure operation under various working conditions.

The interface interface is designed for easy integration with different filtration systems, ensuring convenient installation and compatibility.

The thermal welded construction creates a strong and stable filter structure without the use of adhesives, reducing the risk of contamination and improving reliability.

The optimized pleated structure increases the effective filtration area, enhances dirt-holding capacity, and extends the service life of the filter cartridge.

The multi-layer filtration media combined with support layers provides efficient depth filtration while maintaining structural strength and filtration stability.

The reinforced center core provides internal support, maintains cartridge rigidity, and ensures stable performance during operation.

The sealed end cap design prevents bypass flow, improves sealing performance, and ensures consistent filtration efficiency.

The protective outer shell strengthens the overall structure, protects internal filtration components, and improves mechanical durability.

The upstream support layer protects the filter media from damage caused by pressure fluctuations and ensures reliable filtration performance.

The high-efficiency filtration media provides precise particle retention and effectively removes contaminants from liquids.

The downstream support layer maintains filtration stability, prevents media deformation, and ensures consistent output quality.

The integrated fin handle design allows quick installation and removal, making filter replacement easier and more convenient.
