Pall HFU660UY045H13 – Ultipleat High Flow Pleated Filter Cartridge
Pall HFU660UY045H13 belongs to Pall Ultipleat HFU series coreless wide diameter high flow filter cartridge, widely adopted in industrial raw water pretreatment and RO membrane security filtration systems. Our interchangeable aftermarket HFU660UY045H13 strictly follows original crescent pleat layout, single open-end structure, integrated lifting handle and H13 U-cup sealing dimension for direct plug-and-play installation inside standard Pall high flow filter housings without equipment modification. Constructed with gradient polypropylene pleated media, this replacement cartridge delivers stable high flow rate, reliable 4.5μm particle retention and outstanding dirt holding capacity. Many water treatment EPC partners match HFU640UY700H13W filter cartridge and HFU660GF060H13 glass fiber element with HFU660UY045H13 alternatives to build complete multi-stage water purification workflows.

Product Overview
Pall HFU660UY045H13 utilizes the classic Ultipleat core-free 6-inch wide diameter pleated design with inside-out flow direction. The optimized crescent pleat structure greatly expands effective filtration surface area. As a 60-inch long high flow cartridge with 4.5μm accuracy, it is widely selected for large-scale desalination, power plant and municipal water treatment projects to reduce the total quantity of filter cartridges and lower overall investment of filter vessels. However, high cost and long delivery lead time of genuine Pall HFU660UY045H13 bring budget pressure and project delay risks for plant operators and engineering contractors. Our factory produces fully interchangeable replacement cartridges to achieve equivalent filtration performance with more competitive cost and shorter lead time.
Key specifications of HFU660UY045H13: 6 inch outer diameter, 60 inch nominal length, 4.5μm filtration rating, UY gradient polypropylene media, H13 NBR U-cup seal. End caps, support drainage layers and outer protective wrap adopt reinforced polypropylene raw materials, manufactured by thermal fusion 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 HFU660UY045H13 cartridges passes 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, minimizes RO membrane fouling risk and provides reliable protection for downstream membrane modules, water pumps and precision regulating valves.
Filtration Working Principle
Pall HFU660UY045H13 adopts mature inside-out filtration flow path. Driven by system pressure, raw water enters the inner cavity of the coreless filter cartridge and permeates outward through multi-layer gradient pleated media. Large flocs and coarse sediment are trapped on inner pleated layers, while fine particles and colloids that easily cause membrane pollution are deeply intercepted by outer precision media layers.
Optimized crescent pleat arrangement reduces fluid dead zones and prevents media compression under pressure, maximizing dirt holding capacity. Pollutants remain sealed inside the cartridge during replacement, eliminating 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 H13 U-cup sealing standards; no housing modification required to cut maintenance downtime.
Stable 4.5μm Filtration Grade:
Gradient polypropylene depth media delivers consistent particle removal effect, ideal for medium-precision security filtration before RO membranes.
Ultra-Large Dirt Holding Capacity:
60-inch longer structure provides larger filtration area, slows differential pressure growth and extends service intervals.
Cost & Supply Advantage:
Direct factory supply removes intermediate links and achieves shorter lead times compared with imported genuine HFU660UY045H13 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 municipal water treatment projects
FAQ
Q1: Can aftermarket HFU660UY045H13 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 segment of model HFU660UY045H13 mean?
A2: HFU = Ultipleat High Flow series; 660 = 6 inch OD, 60 inch length; UY = gradient polypropylene pleated media; 045 = 4.5 micron rating; H13 = NBR U-cup sealing structure.
Q3: What differential pressure triggers filter replacement?
A3: The inlet-outlet differential pressure is 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 HFU660UY045H13 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 other micron and seal options available for HFU660 series?
A5: Yes. We supply HFU660 series cartridges with 1μm,4.5μm,6μm,10μm,20μm,40μm,70μm ratings, and optional EPDM, Viton seals besides standard H13 NBR. Please provide exact part number for precise quotation.
