Product Overview
High Flow Filter HFU620GF100H13 adopts classic Ultipleat core-free 6-inch wide diameter pleated design with inside-out flow direction. The optimized crescent pleat structure maximizes effective filtration surface area. As a 20-inch long high flow cartridge with 10μm absolute filtration rating, it is commonly deployed in seawater desalination, power plant water treatment and municipal water supply projects. Adopting this short-length large flow cartridge helps reduce the total quantity of filter cartridges and lowers overall investment of filter vessels. However, high procurement cost and long import lead times of genuine Pall HFU620GF100H13 bring budget pressure and project delay risks to 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 HFU620GF100H13: 6 inch outer diameter, 20 inch nominal length, 10μm absolute filtration rating, GF resin bonded glass fiber media, H13 NBR U-cup seal. End caps, drainage support layers and outer protective wrap are reinforced polypropylene materials. All components adopt thermal fusion molding without adhesive, effectively avoiding fiber shedding and secondary contamination to process water. Glass fiber media features stable pore structure and excellent temperature resistance compared with PP media. The maximum continuous operating temperature reaches 121°C, maximum allowable differential pressure up to 3.4 bar, suitable for 24/7 uninterrupted industrial operation.
Every batch of HFU620GF100H13 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 fine colloids, mitigating RO membrane fouling risks and providing reliable protection for downstream membrane modules, water pumps and precision regulating valves.
Filtration Working Principle
High Flow Filter HFU620GF100H13 follows 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 glass fiber 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 media layers.
Optimized crescent pleat arrangement eliminates 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 H13 U-cup sealing standards; no housing modification required to cut maintenance downtime.
Stable 10μm Absolute Filtration Grade:
Resin-bonded glass fiber media maintains fixed pore structure, delivers steady particle removal efficiency, perfectly suited for medium-precision security filtration and high-temperature working conditions.
Ultra-Large Dirt Holding Capacity:
Scientific crescent pleated layout expands filtration area, slows differential pressure growth and extends service intervals.
Excellent Thermal Stability:
GF glass fiber media withstands higher operating temperature than conventional polypropylene filter cartridges.
Cost & Supply Advantage:
Direct factory supply removes intermediate links and offers shorter lead times compared with imported genuine HFU620GF100H13 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

FAQ
Q1: Can aftermarket HFU620GF100H13 be directly installed into original Pall Ultipleat filter housings?
A1: Yes. All critical dimensions and H13 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 HFU620GF100H13 represent?
A2: HFU = Ultipleat High Flow series; 620 = 6 inch OD, 20 inch length; GF = resin bonded glass fiber media; 100 = 10 micron rating; H13 = NBR U-cup sealing configuration.
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 HFU620GF100H13 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 GF series?
A5: Yes. We supply HFU620 series GF media cartridges with 1μm,4.5μm,6μm,10μm,20μm ratings, and optional H13, J, H1, EPDM, Viton seals. Please provide exact part number for precise quotation.
