Pall HFU Series Large Flow Water Filter Element is the flagship Ultipleat coreless wide-diameter pleated filtration series launched by Pall Corporation, covering full-size industrial high-flow water treatment specifications. It is widely applied in seawater desalination, power plant water supply, petrochemical process water and large-scale RO security filtration systems. Our aftermarket Pall HFU Series Large Flow Water Filter Element fully duplicates the original crescent pleat structure, single open-end integrated handle and multi-type sealing standards, realizing 100% drop-in replacement for genuine Pall filter housings without equipment modification. Supported by gradient polypropylene and microglass media options, the HFU series features ultra-high flow rate, hierarchical gradient filtration and super-large dirt holding capacity. Most EPC contractors and industrial end-users adopt matched combinations of HFU640UY700H13W coarse filtration cartridge and HFU660UY045H13 precision filter element to build stable and efficient multi-stage industrial water treatment systems.

Product Overview
Pall HFU Series Large Flow Water Filter Element represents the advanced high-capacity filtration technology of Pall Ultipleat platform. Different from traditional small-diameter multi-cartridge combination filtration, the HFU series adopts a 6-inch wide-diameter core-free design with optimized crescent pleat arrangement, which dramatically increases the effective filtration area. A single HFU large flow element can replace multiple conventional small cartridges, effectively reducing the number of filter elements, filter housing volume and overall system operation costs for large-flow working conditions.
The complete HFU series product line covers 20/40/60 inch standard lengths, with filtration precision ranging from 1μm to 100μm, fully covering coarse filtration, medium filtration and fine security filtration demands in industrial water treatment. Two mainstream industrial-grade filter media are optional: UY gradient polypropylene media for universal aqueous and mild chemical fluid filtration, and GF microglass media for high-precision fine particle interception and strict membrane protection scenarios.
All HFU series elements adopt full thermal fusion integrated molding process without adhesive bonding, eliminating fiber shedding and secondary fluid contamination. Multiple sealing configurations including H, H13, J, EPDM and Viton are available to adapt to different temperature and chemical resistance requirements. The series supports a maximum continuous operating temperature of 82°C and a maximum differential pressure of 3.4 bar, adapting to 24/7 long-term heavy-duty industrial operation.
Genuine Pall HFU series elements have stable performance but suffer from high procurement costs and long import delivery cycles. Our factory-produced replacement HFU series large flow filter elements pass strict dimensional calibration, bubble point efficiency testing and pressure tightness inspection, ensuring completely consistent interchangeability and operational performance with original products, providing cost-effective and fast-supply replacement solutions for global industrial users.
Filtration Working Principle
All Pall HFU Series Large Flow Water Filter Elements follow the standard inside-out gradient filtration principle. Driven by system operating pressure, raw water enters the inner cavity of the coreless filter element and penetrates outward layer by layer through multi-layer gradient pleated media.
The unique gradient structural design realizes hierarchical impurity interception: large suspended solids, sediment and flocs are trapped by the inner coarse pleated layer, while tiny colloids, fine particles and organic pollutants that easily cause membrane fouling are deeply intercepted by the outer high-precision media layer. The optimized crescent pleats eliminate fluid dead zones, reduce flow resistance, and maintain stable high-flow output throughout the service cycle. All intercepted pollutants are locked inside the filter element, avoiding secondary leakage and clean water pollution during replacement.
When the system inlet and outlet differential pressure rises to 25–35 PSID, the filter media reaches the dirt holding saturation limit. Timely replacement is required to restore the system’s rated high flow and filtration accuracy.
Core Competitive Advantages
Full Series Interchangeability:
Covers all mainstream HFU models and specifications, perfectly matching original size, handle structure and multi-type sealing standards, plug-and-play without housing modification.
Ultra-High Flow & Large Dirt Holding Capacity:
Wide-diameter crescent pleated design expands filtration area greatly, reduces cartridge usage, slows pressure difference rise and extends service life.
Dual Professional Media Customization:
Gradient PP media for universal industrial water treatment; microglass media for high-precision filtration and critical membrane protection working conditions.
Glue-Free Thermal Fusion Process:
Integral thermal fusion molding avoids fiber shedding and adhesive contamination, ensuring pure fluid filtration and long-term stable operation.
Cost & Delivery Advantages:
Factory direct sales eliminate intermediate links, with sufficient stock of conventional models and much shorter lead time than imported genuine elements.
Main Application Scenarios

Food, beverage and pharmaceutical process water filtration
Industrial wastewater reuse and municipal large-scale water treatment projects
FAQ
Q1: Are your replacement Pall HFU series elements fully compatible with original Pall filter housings?
A1: Yes. All structural dimensions, interface positions and sealing parameters are strictly benchmarked against original standards, supporting direct plug-and-play installation with zero modification.
Q2: How to select the right media and precision for HFU series filter elements?
A2: For conventional raw water pretreatment, choose gradient polypropylene media with 20–70μm precision for coarse filtration; for RO front-end precision security filtration, select microglass media or high-precision PP media with 1–10μm to protect membrane elements.
Q3: What is the standard replacement cycle for HFU large flow filter elements?
A3: The core judgment index is system differential pressure. Replace timely when the pressure difference reaches 25–35 PSID. High-turbidity raw water working conditions require shorter replacement intervals.
Q4: Can Pall HFU series filter elements be reused after cleaning?
A4: HFU series belongs to disposable depth pleated filter elements. Fine colloids and micro-impurities will penetrate into the media pores, and conventional backwashing cannot restore the original filtration efficiency, so replacement is recommended.
Q5: Can you provide customized HFU series filter specifications?
A5: Yes. We support customized length, micron rating, sealing type and special material configuration. Please provide working conditions and original part number for professional targeted matching and quotation.
