HFU620CAS010JUW – Pall Ultipleat High Flow Pleated Filter Cartridge

Product Overview
HFU620CAS010JUW adopts classic Ultipleat core‑free 6‑inch wide‑diameter pleated design with inside‑out flow direction. Optimized crescent pleat structure maximizes effective filtration surface area. As a 20‑inch long high‑flow cartridge with 1μm absolute filtration rating, it is commonly deployed in seawater desalination, power plant condensate polishing, petrochemical circulating water and municipal water supply projects. Adopting this short‑length large‑diameter cartridge helps reduce total filter quantity and lower overall investment for filter vessels. However, high procurement cost and long import lead‑times of genuine Pall HFU620CAS010JUW bring budget pressure and project‑delay risks for plant operators and engineering contractors. Our factory manufactures fully interchangeable replacement cartridges to achieve equivalent filtration indicators with competitive pricing and shorter delivery cycle.
Core specifications of HFU620CAS010JUW: 6 inch outer diameter, 20 inch nominal length, 1μm absolute filtration rating, CAS absolute‑grade polypropylene pleated media, JUW EPDM U‑cup seal. End caps, drainage support layers and outer protective wrap are reinforced polypropylene materials. All components adopt thermal‑fusion molding without adhesive bonding, effectively avoiding fiber shedding and secondary contamination to process water. The maximum continuous operating temperature reaches 82°C, maximum allowable differential pressure up to 3.4 bar, suitable for 24/7 uninterrupted industrial operation.
Every batch of HFU620CAS010JUW cartridges undergoes dimensional tolerance inspection, bubble‑point efficiency testing and pressure‑tightness verification to guarantee seamless interchangeability. It efficiently intercepts fine suspended solids, pipeline rust, sediment and tiny colloids, alleviating RO membrane fouling risks and offering reliable protection for downstream membrane modules, water pumps and precision regulating valves.
Filtration Working Principle
HFU620CAS010JUW follows mature inside‑out gradient 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 polypropylene pleated media. Coarse sediment and large flocs are trapped on inner pleated layers, while fine particles and colloids that easily cause membrane clogging are deeply intercepted by outer precision CAS media layers.
Optimized crescent pleat arrangement minimizes 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 cartridges promptly once inlet‑outlet differential pressure rises to 25‑35 PSID to restore system rated‑flow performance.
Core Competitive Advantages
Full Drop‑in Interchangeability:
Consistent with original outer dimensions, end‑cap geometry, lifting handle and JUW EPDM U‑cup sealing standards; no housing modification required to cut maintenance downtime.
Stable 1μm Absolute Filtration Grade:
CAS absolute polypropylene media delivers steady fine‑particle interception performance, perfectly suited for RO front‑end high‑precision security filtration.
Large Dirt‑Holding Capacity: Scientific crescent‑pleat layout expands filtration area, slows differential‑pressure growth and extends service intervals.
Broad Chemical Compatibility:
All‑polypropylene construction provides good compatibility for most aqueous industrial fluids.
Cost & Supply Advantage:
Direct factory supply removes intermediate links and achieves shorter lead‑times compared with imported genuine HFU620CAS010JUW cartridges.
Strict Batch 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
Electronic industry ultrapure water pretreatment
Industrial wastewater reuse advanced filtration
Large‑scale municipal water treatment projects
FAQ
Q1: Can aftermarket HFU620CAS010JUW be directly installed into original Pall Ultipleat filter housings?
A1: Yes. All critical dimensions and JUW EPDM U‑cup sealing structure comply with original design standards. Plug‑and‑play installation is supported without extra accessories or vessel adjustments.
Q2: What does each segment of model HFU620CAS010JUW stand for?
A2: HFU = Ultipleat High Flow series; 620 = 6 inch OD, 20 inch length; CAS = absolute‑grade polypropylene media; 010 = 1 micron rating; JUW = EPDM U‑cup sealing configuration with customized W version.
Q3: What differential pressure triggers 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 HFU620CAS010JUW 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: Are alternative micron ratings and seal styles available for HFU620 CAS series?
A5: Yes. We supply HFU620‑series CAS media cartridges with 1μm,4.5μm,6μm,10μm,20μm,40μm ratings, and optional J, JU, H13, EPDM, Viton seals. Please provide exact part number for precise quotation.
