Product Overview
PALL High Flow Water Filter Cartridge HFU640UY700H13W adopts classic Ultipleat core-free 6-inch wide-diameter pleated design, with inside-out flow direction. Compared with conventional small-diameter filter cartridges, the optimized crescent pleat structure greatly expands effective filtration area. This model is widely selected for large-scale water treatment systems to reduce the total quantity of filter elements and cut equipment investment. However, high cost of genuine HFU640UY700H13W cartridges and long uncertain delivery cycles bring budget pressure and project delay risks to plant operators and engineering contractors. Our factory develops fully interchangeable replacement filter cartridges to provide economical solutions while reaching equivalent filtration technical indicators.
Core specifications of HFU640UY700H13W: outer diameter 6 inch (152.4mm), 40-inch nominal length, 70μm filtration rating, H13 NBR U-cup seal, polypropylene pleated media. Supporting components including end caps, drainage layers and outer wrap all adopt reinforced polypropylene materials, manufactured by thermal fusion without adhesive, effectively avoiding fiber shedding and secondary fluid contamination. The maximum continuous operating temperature reaches 82°C, maximum allowable differential pressure up to 3.4 bar, suitable for long-term 24/7 continuous industrial operation.
Every batch of finished HFU640UY700H13W cartridges undergoes dimensional tolerance inspection, bubble point efficiency testing and pressure tightness verification to guarantee seamless interchangeability. It efficiently intercepts suspended solids, pipeline rust, sediment and coarse colloids, mitigating membrane fouling risks and offering effective protection for downstream RO/NF membrane modules, water pumps and precision regulating valves.
Filtration Working Principle
PALL High Flow Water Filter Cartridge HFU640UY700H13W applies the mature inside-out filtration flow path. Driven by system operating pressure, raw water enters the inner cavity of the coreless filter cartridge and permeates outward through multi-layer gradient pleated media. Coarse sediment and large flocs are trapped on inner pleated layers, while micro-particles and colloids that easily induce membrane pollution are deeply intercepted by outer precision media layers.
Optimized crescent pleat design reduces fluid dead zones and prevents media compression under pressure, maximizing dirt holding capacity. Pollutants remain enclosed inside the cartridge during replacement, avoiding secondary particle leakage and contamination of clean water pipelines. After purification, treated water flows into subsequent separation processes. Operators should replace filter cartridges promptly once inlet-outlet differential pressure rises to 25–35 PSID to restore the system’s rated flow rate.
Core Competitive Advantages
Full Drop-in Interchangeability:
Consistent with original outer dimensions, end cap geometry, lifting handle and H13 U-cup sealing standards; no housing modification required to cut maintenance downtime.
Stable 70μm Filtration Grade:
Gradient polypropylene depth media ensures consistent particle removal performance, ideal for primary pretreatment of raw water.
Outstanding Dirt Holding Capacity:
Enlarged effective filtration surface slows differential pressure growth and extends service intervals.
Cost & Supply Advantage:
Direct factory supply removes intermediate links and delivers shorter lead times compared with imported genuine HFU640UY700H13W cartridges.
Standardized Quality Control:
Complete testing procedures ensure stable performance for large-scale engineering orders.
Main Application Scenarios
Seawater & brackish water desalination RO security pre-filtration
Thermal power plant boiler make-up water and condensate polishing
Petrochemical circulating water and process liquid purification
Industrial raw water pretreatment
Industrial wastewater reuse advanced filtration
Large municipal water treatment projects
FAQ
Q1: Can aftermarket HFU640UY700H13W be directly installed into original Pall Ultipleat filter housings?
A1: Yes. All critical dimensions and H13 sealing structure comply with original design standards. Plug-and-play installation is supported without extra accessories or vessel adjustments.
Q2: What does each section of model HFU640UY700H13W stand for?
A2: HFU=Ultipleat High Flow series; 640=6 inch OD, 40 inch length; UY=polypropylene pleated media; 700=70 micron rating; H13=NBR U-cup seal; W represents customized structural configuration.
Q3: What differential pressure value signals filter replacement?
A3: The inlet-outlet differential pressure serves as the core judging indicator. When pressure difference reaches 25–35 PSID, filter media is heavily clogged. Systems with high influent turbidity require shorter replacement cycles.
Q4: Can HFU640UY700H13W filter cartridge be backwashed and reused?
A4: It belongs to disposable pleated filter consumables. Fine colloids and micro-particles embed deep into media pores. Conventional backwashing cannot fully recover initial filtration efficiency, so timely replacement is advised.
Q5: Can you provide other micron alternatives based on HFU640 series?
A5: Yes, we supply HFU640 series cartridges with 1μm,4.5μm,10μm,20μm,40μm,70μm,100μm ratings, different seal options (H13/J/EPDM). Please confirm exact part number for quotation.
