Product Overview
Pall HFU660GF020H Ultipleat adopts the 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 60-inch long filter cartridge with 20μm absolute filtration rating, it is widely adopted in seawater desalination, power plant water treatment and municipal water supply projects. Adopting this long-sized cartridge helps reduce the total quantity of filter cartridges and lowers the overall investment of filter vessels. However, high procurement cost and long import lead times of genuine Pall HFU660GF020H bring budget pressure and project delay risks to plant operators and engineering contractors. Our factory manufactures fully interchangeable replacement cartridges, achieving equivalent filtration indicators with competitive pricing and faster delivery cycle.
Core specifications of HFU660GF020H: 6 inch outer diameter, 60 inch nominal length, 20μm filtration rating, GF resin bonded glass fiber media, H standard sealing structure. End caps, drainage support layers and outer protective wrap are manufactured from reinforced polypropylene. All components adopt thermal fusion molding without glue, effectively avoiding fiber shedding and secondary pollution to process water. Glass fiber media features stable pore structure, excellent temperature resistance and consistent particle interception efficiency compared with PP media. The maximum continuous operating temperature reaches 121°C, maximum allowable differential pressure up to 3.4 bar, suitable for long-term 24/7 continuous industrial operation.
Every batch of HFU660GF020H 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, reduces RO membrane fouling risks and provides reliable protection for downstream membrane modules, water pumps and precision regulating valves.
Filtration Working Principle
Pall HFU660GF020H Ultipleat 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 flows outward through multi-layer gradient pleated media. Coarse sediment and large flocs are trapped on inner pleated layers, while fine particles and colloids that easily cause membrane contamination are deeply intercepted by outer precision glass fiber 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 clean pipeline contamination. 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 H-type sealing standards; no housing modification required to cut maintenance downtime.
Stable 20μm Absolute Filtration Grade:
Resin-bonded glass fiber media maintains fixed pore structure, delivers steady particle removal efficiency, perfectly suited for medium-coarse security filtration with high temperature working conditions.
Ultra-Large Dirt Holding Capacity:
60-inch extended structure provides larger filtration area, slows differential pressure growth and extends service intervals.
Cost & Supply Advantage:
Direct factory supply removes intermediate links and offers shorter lead times compared with imported genuine HFU660GF020H 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 high-temperature process liquid purification
Industrial raw water pretreatment
Industrial wastewater reuse advanced filtration
Large municipal water treatment projects
FAQ
Q1: Can aftermarket HFU660GF020H be directly installed into original Pall Ultipleat filter housings?
A1: Yes. All critical dimensions and H-type 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 HFU660GF020H represent?
A2: HFU = Ultipleat High Flow series; 660 = 6 inch OD, 60 inch length; GF = resin bonded glass fiber media; 020 = 20 micron rating; H = standard H sealing configuration.
Q3: What differential pressure value signals filter replacement?
A3: The inlet-outlet differential pressure acts 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 HFU660GF020H filter cartridge be backwashed and reused?
A4: It belongs to disposable pleated filter consumables. Fine colloids and micro-particles penetrate deep into media pores. Conventional backwashing cannot fully recover initial filtration efficiency, so timely replacement is recommended.
Q5: Are alternative micron ratings and seal styles available for HFU660 GF series?
A5: Yes. We supply HFU660 GF media cartridges with 1μm,4.5μm,6μm,10μm,20μm ratings, and optional H, H13, J, EPDM, Viton seals. Please offer the exact part number for accurate quotation.
