HFU640UY100J Replacement High Flow Filter Cartridge
Introduction:If you are sourcing HFU640UY100J replacement high flow filter cartridge for industrial RO pre-filtration and process water purification, this drop-in interchange element adopts UY-series polypropylene pleated media with 10-micron filtration rating. It delivers ultra-large effective filtration area, outstanding dirt-holding capacity and high single-cartridge flow performance, effectively capturing suspended solids, silt, rust particles and colloidal contaminants. It serves as critical security pre-filter to protect reverse osmosis membrane systems and reduce membrane fouling risk. The special crescent-laid pleat geometry minimizes total cartridge quantity inside filter housings. As cost-effective replacement from Chinese manufacturer, it fits heavy-duty water-treatment projects for global EPC and industrial end-users, fully compatible with Pall Ultipleat HFU series filter vessels.

Product Overview
HFU640UY100J belongs to Ultipleat high flow filter series, 40-inch nominal length, 6-inch (152.4 mm) large outer diameter, core-less single open-end structure, inside-to-outside flow pattern. The filter media is proprietary UY-grade polypropylene pleated material with 10 μm removal rating (Beta 100). End caps and integrated lifting handle adopt glass-fiber reinforced polypropylene material. Standard O-ring seal is EPDM, and optional silicone, Buna-N and FKM seals support various chemical working conditions. Thermal welding connection without adhesive avoids secondary contamination risk. Unique crescent-shaped laid-over pleat structure greatly expands filtration area, achieves high flow rate with fewer cartridges and downsizes filter housing investment. This interchangeable filter cartridge is widely applied in seawater desalination, power plant water system, petrochemical process water, municipal water works and large-scale RO security filtration projects.
Working Principle
HFU640UY100J high flow filter cartridge runs under inside-to-outside flow direction. Raw liquid enters from inner open-end inlet, flows radially outward through multi-layer pleated polypropylene media. Large-size impurities are trapped on inner pleated layers, fine particles are intercepted by depth-filtration effect inside pleated gaps. The special overlapping pleat geometry optimizes particle holding space and slows down pressure-drop rising speed. After full purification, qualified liquid flows out from the outer surface of filter media. Reliable O-ring sealing prevents unfiltered fluid bypass. All intercepted pollutants remain inside the cartridge, convenient for safe replacement and waste disposal. It undertakes security pre-filtration work, greatly lowering impurity load for downstream RO, NF membrane and ion-exchange resin equipment.
Core Technical Specifications
Core Advantages
Core-less unique crescent pleat design:
Without internal support skeleton, special laid-over pleat geometry maximizes filtration area, realizes high flow with fewer filter cartridges, reduces housing quantity and overall project investment cost.
10-micron reliable depth filtration:
UY-grade polypropylene media provides stable particle interception performance, delivers trustworthy pre-treatment protection for reverse osmosis membrane systems.
Excellent chemical compatibility:
Full polypropylene construction features good acid-alkali tolerance, adapts to various industrial water and general process-liquid working conditions. Multiple sealing material options meet diverse corrosive fluid requirements.
Easy-maintenance single open-end structure:
Built-in lifting handle enables quick tool-free replacement; intercepted pollutants stay inside the filter element for safer handling. Thermal-welded structure eliminates adhesive pollution risk.
Economical drop-in replacement solution:
Manufactured by LEFILTER China. It matches original dimension, interface and flow performance, helps global industrial clients and engineering contractors cut spare-part procurement expenditure by 60-70%.
Main Application Scenarios
Reverse osmosis security pre-filtration for seawater desalination plants
Power plant boiler feed-water and condensate-water pretreatment

Large-scale municipal water-supply pretreatment system
Ion-exchange resin protection filtration for water-treatment workshops
Industrial circulating water and wastewater reuse pre-filtration
Compatibility & Cross Reference
FAQ
Q1: Can HFU640UY100J fit my existing Pall filter housing?
A1: Yes. It adopts 40-inch length, 6-inch outer diameter, core-less single open-end inside-to-outside flow structure, fully matching Pall Ultipleat HFU640 series filter vessels. No modification needed.
Q2: When shall I replace HFU640UY100J filter cartridge?
A2: Replace when differential pressure rises to 2.0 bar (29 psid). Actual service life depends on raw-water impurity concentration, typically 3-6 months for normal industrial water pretreatment.
Q3: What is maximum operating temperature for HFU640UY100J?
A3: Max continuous operating temperature reaches 82℃. Long-term service beyond this temperature will cause polypropylene media deformation and degrade filtration efficiency.
Q4: Are other micron grades available for this UY-series?
A4: Yes. Corresponding series provides 2 μm, 4.5 μm, 6 μm, 10 μm, 20 μm, 40 μm, 70 μm. Custom specifications are supported for bulk-order projects.
Q5: What is production lead-time for bulk HFU640UY100J orders?
A5: For standard-spec cartridges, lead-time is 7-15 working days upon deposit confirmation. Customized requirements need extra production cycle.
