What are the five major advantages of PES folding filter cartridges?

PES folded filter cartridges are inherently hydrophilic and do not require water immersion before use. They can be directly used for water filtration, which is very convenient. During the filtration process, they are not only easy to install and operate but also highly stable, with minimal risk of drying out. Their hydrophilic nature ensures excellent filtration performance.

PES folded filter cartridges are manufactured through welding, forming a single piece through hot melt welding. This process eliminates the need for adhesives, thus avoiding secondary pollution. Additionally, their low water solubility allows them to extract non-volatile residues and impurities, meeting the FDA's biological safety requirements.

In the biopharmaceutical industry, PES folded filter cartridges are the preferred choice for filtering impurities. This is mainly due to their extremely low protein adsorption, which is a core advantage over other filter cartridges. Their material properties minimize protein adsorption, ensuring very low adsorption of proteins, antibodies, and other biomolecules, effectively guaranteeing the survival rate and collection of target products, making them the preferred filter cartridges in the biopharmaceutical industry and vaccine production.

The structure of PES folded filter cartridges features an asymmetric pore structure, which provides high flow rate and low pressure drop. The folding process increases the filtration area, enhancing the dirt-holding capacity and extending the service life under various operating conditions.

PES folded filter cartridges have extremely high precision, capable of retaining bacteria with a precision of 0.22 microns, meeting the sterilization grade standard. Each cartridge undergoes various tests before leaving the factory, ensuring reliable performance.
