Product Overview
Pall Ultipleat High Flow Filter adopts innovative coreless pleated construction, greatly expanding effective filtration area compared to conventional small diameter filter cartridges. Original HFU series elements have long been the preferred selection for large-scale industrial liquid purification worldwide. Nevertheless, high original purchasing cost and extended delivery lead times bring obvious budget pressure and project scheduling risks for end users. Our factory-developed replacement filter cartridges provide a reliable economical alternative while meeting the same filtration benchmarks as genuine Pall components.
The product range covers mainstream specifications: 20”, 40” and 60” lengths, filtration ratings ranging from 1μm to 50μm. Two primary media choices are offered: gradient polypropylene media for general aqueous filtration and micro glass fiber media for high-precision fine particle capture. Thermal fusion manufacturing eliminates glue contamination and fiber shedding risks. Sealing materials including Buna-N, EPDM and Viton are optional to accommodate varying temperatures and mild chemical environments. Maximum continuous operating temperature reaches 82°C, with a maximum allowable differential pressure of 3.4 bar, suitable for nonstop 24/7 industrial operation.
All finished filter cartridges undergo strict dimensional verification, bubble point efficiency testing and pressure tightness inspection to guarantee seamless interchangeability. The filter efficiently traps suspended solids, pipeline rust, sediment and fine colloids, effectively mitigating membrane fouling and protecting downstream RO/NF membranes, pumps and precision control valves.
Filtration Working Principle
Pall Ultipleat High Flow Filter adopts the proven inside-out filtration flow path. Driven by system operating pressure, raw liquid enters the inner cavity of the coreless filter cartridge and permeates outward through multi-layer gradient pleated media. Large flocs and coarse sediment are retained by inner pleated layers, while micro-particles and colloids that easily cause membrane contamination are deeply intercepted by outer precision media layers.
The optimized crescent pleat layout minimizes fluid dead zones and prevents media compression, maximizing dirt holding capacity. During cartridge replacement, pollutants remain enclosed inside the element, avoiding secondary particle leakage and clean fluid contamination. After purification, treated water flows into subsequent separation processes. Operators are advised to replace cartridges promptly once inlet-outlet differential pressure climbs to 25–35 PSID to recover the designed rated flow rate.
Core Competitive Advantages
100% Drop-in Compatibility:
Matches original outer size, end cap geometry, handle and O-ring positions; no housing retrofitting required to cut maintenance downtime.
Two Professional Media Options:
Polypropylene media for universal water treatment; glass fiber media for high absolute efficiency and strict membrane protection demands.
Enhanced Dirt Holding Capacity:
Enlarged effective filtration surface slows differential pressure rise and extends service intervals.
Cost-Effective Sourcing Option:
Direct factory supply removes intermediate costs and provides shorter lead times compared with imported original filters.
Standardized Batch Testing:
Consistent quality control ensures stable performance for large engineering orders and long-term plant operation.
Main Application Scenarios

FAQ
Q1: Can aftermarket Pall Ultipleat High Flow Filter be fitted directly into original Pall filter housings?
A1: Yes. All critical dimensions and interface structures follow original specifications. Direct plug-and-play installation is available without extra accessories or housing adjustments.
Q2: When should users select glass fiber media instead of PP media?
A2: Glass fiber media delivers higher absolute filtration efficiency for fine particle removal. It is recommended for critical applications where thorough RO membrane protection is required. Polypropylene media features superior broad chemical resistance for general raw water filtration.
Q3: What is the standard trigger point for filter replacement?
A3: Differential pressure between inlet and outlet serves as the key indicator. When pressure difference reaches 25–35 PSID, the filter media is heavily clogged. Systems with high influent turbidity require more frequent replacement.
Q4: Is the Pall Ultipleat High Flow Filter reusable after backwashing?
A4: This series belongs to disposable pleated filter consumables. Fine colloids and micro-particles embed deep into media pores. Regular backwashing cannot restore original filtration efficiency, so timely replacement is recommended.
Q5: What information is needed to confirm model matching and quotation?
A5: Please provide original part number, cartridge length, micron rating, seal material, operating temperature and fluid medium. Our technical team will verify compatibility and offer targeted filtration solutions.
