Double layer polyether sulfone filter cartridge

The F2SD series filter cartridge is made of double-layer hydrophilic polyether sulfone membrane (PES) and PP skeleton. The membrane material is made of imported asymmetric PES membrane and imported non-woven fabric and wire mesh as the support layer, folded together. The large filtration area of up to 1.2 square meters makes the filter cartridge have high pollutant holding capacity. The double-layer membrane design makes it have ultra-high retention efficiency. The filter cartridge has good heat resistance and can withstand multiple steam sterilization. Each filter cartridge passes integrity testing before leaving the factory.

characteristic advantages

• Double layer membrane design provides reliable bacterial retention capability
• Ultra large filtration area, with a long service life
• Wide chemical compatibility makes it suitable for various filtration applications
• Integrity testing provides greater assurance and ultra-low diffusion flow
• Each filter element undergoes integrity testing before leaving the factory, ensuring more reliable sterilization filtration.

Typical Applications

• Sterilization filtration of small injection (SVP)
• Sterilization and filtration of freeze-dried powder injections
• Filtration of traditional Chinese medicine injections
• Filtration of biological products and vaccines
• Purification and filtration of high-purity chemical reagents
• Terminal filtration of semiconductor wet equipment
