Product Introduction:
The NF series is the flagship product of Xinghe HF high flow filter cartridge product line, with a core filtration medium of multi-layer nanofiber composite membrane. Through high-density gradient folding technology, the filtration area of a single 60 inch filter element reaches 8.4m ², and with the gradient fiber layer structure, it achieves 2-3 times the pollutant holding capacity and an absolute retention efficiency of ≥ 99% compared to the same level PP series. Specially designed for high cleanliness scenarios such as RO reverse osmosis security filtration, ultrapure water preparation, and biopharmaceuticals.
Application fields:
RO reverse osmosis: RO membrane security filtration (core application), protecting the reverse osmosis membrane and extending the cleaning cycle
◎ Seawater desalination: SWRO system precision pre filtration reduces membrane fouling and blockage rate
◎ Electricity: Supercritical/ultra supercritical boiler feedwater precision treatment
◎ Electronics industry: Ultra pure water (UPW) system pre filtration, chip cleaning water treatment
◎ Pharmaceutical: Pre filtration of water for injection (WFI), fine filtration of raw material solution
Product Features:
Multi layer nanofiber structure: 5-7 layers of nano scale fiber membrane stacking: outer layer intercepts large particles+inner layer nano scale precision interception, gradient utilization of full depth pollutant absorption space.
Ultra high filtration efficiency: The target precision particle retention efficiency is ≥ 99%, far superior to the 95% -98% of traditional PP/GF filters; The retention efficiency for particles with a precision greater than twice the nominal accuracy is ≥ 99.99%.
◎ Super large filtration area: 60 inch single tube 8.4m ², 40 inch 5.6m ², leading in the same level of products.
◎ Ultra large pollutant absorption capacity: The gradient structure efficiently utilizes full depth pollutant absorption, with a pollutant absorption capacity 2-3 times that of the same precision PP series.
◎ Low pressure differential operation: Optimize the flow channel design to reduce the operating pressure differential by 15% -25% compared to the standard PP series at the same flow rate.
◎ Double layer polyester mesh cover: The inner and outer layers are densely protected, and the anti crushing ability is about 40% higher than that of a standard single mesh cover.
◎ Double sealing structure: Optimize the sealing ring section to match the limit groove, eliminating the risk of leakage under high pressure conditions.
Ergonomic handle: quick installation and removal, supports one handed operation, improves maintenance efficiency.
