Product Overview
Pall Ultipleat High Flow Element features a distinctive core-free wide-diameter design, greatly boosting effective filtration area compared to conventional small-diameter filter cartridges. The original HFU series has become a mainstream choice for large-flow industrial water treatment globally. However, high cost of genuine elements and lengthy delivery cycles create budget risks and project delays for plant owners and engineering contractors. Our replacement filter elements deliver equivalent filtration performance and serve as a reliable cost-saving solution.
Our product portfolio covers mainstream specifications including 20”, 40” and 60” lengths, with filtration ratings ranging from 1μm to 50μm. Two primary media types are available: gradient polypropylene pleated media for general aqueous applications and micro glass fiber media for high-precision fine particle interception. Thermal fusion technology eliminates adhesive usage to avoid fiber shedding and fluid contamination. Sealing materials including Buna-N, EPDM and Viton are optional to adapt to different temperature and mild chemical service environments. The maximum continuous operating temperature reaches 82°C, with maximum allowable differential pressure up to 3.4 bar, suitable for long-term 24/7 continuous industrial operation.
All finished elements pass dimensional tolerance inspection, bubble point efficiency testing and pressure tightness verification to guarantee reliable interchangeability. It effectively captures suspended solids, pipeline rust, sediment and fine colloids, minimizing membrane fouling and offering effective protection for downstream RO/NF membranes, water pumps and precision regulating valves.
Filtration Working Principle
Pall Ultipleat High Flow Element follows the mature inside-out filtration principle. Driven by system pressure, raw fluid flows into the inner cavity of the coreless filter element and penetrates outward through multi-layer gradient pleated media. Coarse sediment and large flocs are trapped by inner pleated layers, while micro-particles and colloids that easily induce membrane contamination are deeply intercepted by outer precision media layers.
Optimized crescent pleat arrangement reduces fluid dead zones and prevents media deformation under pressure, maximizing dirt holding capacity. Pollutants remain sealed inside the element during replacement, preventing secondary particle leakage and contamination of clean fluid pipelines. After purification, treated fluid flows into subsequent separation processes. Operators should replace filter elements promptly once inlet-outlet differential pressure rises to 25–35 PSID to restore system rated flow capacity.
Core Competitive Advantages
Fully Drop-in Interchangeable: Consistent with original outer dimension, end cap structure, handle and sealing specifications; no housing modification required to cut maintenance downtime.
Optional Dual Filter Media: Polypropylene media with universal chemical compatibility for conventional pretreatment; glass fiber media for high absolute efficiency to satisfy strict membrane protection requirements.
Excellent Dirt Holding Capacity: Enlarged effective filtration surface slows differential pressure growth and extends service cycles.
Economical Procurement Option: Factory direct supply removes intermediate links and delivers shorter lead time compared with imported genuine elements.
Strict Batch Quality Control: Complete testing standards ensure stable performance for large-scale engineering orders.

FAQ
Q1: Can aftermarket Pall Ultipleat High Flow Element be directly installed in original Pall filter housings?
A1: Yes. All key dimensions, interface and O-ring positions comply with original design standards. Plug-and-play installation is supported without extra accessories or vessel adjustments.
Q2: How to select suitable media for Pall Ultipleat High Flow Element?
A2: Polypropylene media is preferred for general raw water treatment with broad chemical tolerance. Glass fiber media achieves higher absolute efficiency and is recommended for projects requiring strict fine particle removal and RO membrane protection.
Q3: What differential pressure value indicates filter replacement?
A3: The inlet-outlet differential pressure acts as the main judging indicator. When pressure difference reaches 25–35 PSID, media is heavily clogged. High-turbidity raw water requires shorter replacement intervals.
Q4: Can Pall Ultipleat High Flow Element be backwashed and reused?
A4: It is a disposable pleated filter consumable. Fine colloids and micro-particles embed deeply into media pores. Conventional backwashing cannot fully recover initial filtration efficiency, so timely replacement is recommended.
Q5: What specifications need to be confirmed before quotation?
A5: Please provide original part number, element length, micron rating, required seal material, operating temperature and working medium. Our technical team will confirm compatibility and provide targeted solutions.
