Product Overview
Pall Ultipleat Filter adopts an innovative core-free pleated design, which greatly expands effective filtration area compared with traditional small-diameter filter cartridges. The original HFU series has long become a mainstream selection for large-flow industrial water treatment globally. Nevertheless, high price of genuine products and unpredictable long lead times bring budget pressure and project delay risks to plant owners and engineering contractors. Our factory produces fully compatible replacement filter cartridges, offering reliable cost-saving solutions while reaching equivalent filtration standards.
The product lineup covers mainstream specifications: 20-inch, 40-inch and 60-inch lengths, filtration ratings ranging from 1μm to 50μm. Two primary media options are provided: gradient polypropylene pleated media for general aqueous filtration and micro glass fiber media for high-precision fine particle removal. Thermal fusion manufacturing removes adhesive application, effectively preventing fiber shedding and secondary fluid contamination. Sealing materials including Buna-N, EPDM and Viton are optional to adapt to various temperature and mild chemical environments. The maximum continuous operating temperature reaches 82°C, maximum allowable differential pressure up to 3.4 bar, suitable for nonstop 24/7 heavy-duty industrial operation.
All finished filters undergo strict dimensional inspection, bubble point efficiency testing and pressure tightness verification to guarantee seamless interchangeability. It efficiently captures suspended solids, pipeline rust, sediment and fine colloids, alleviating membrane fouling and delivering reliable protection for downstream RO/NF membranes, water pumps and precision regulating valves.
Filtration Working Principle
Pall Ultipleat Filter applies the mature inside-out filtration principle. Driven by system pressure, raw fluid 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 by inner pleated layers, while micro-particles and colloids that easily trigger membrane contamination are deeply intercepted by outer precision media layers.
Optimized crescent pleat arrangement reduces fluid dead zones and avoids media compression under pressure, maximizing dirt holding capacity. Pollutants remain enclosed inside the cartridge during replacement, preventing secondary particle leakage and clean fluid pipeline contamination. After purification, treated fluid flows into subsequent separation processes. Operators should replace cartridges promptly once inlet-outlet differential pressure rises to 25–35 PSID to restore the system’s rated flow rate.
Core Competitive Advantages
100% Drop-in Interchangeability:
Consistent with original outer dimensions, end cap shape, handle and sealing standards; no housing modification required to lower maintenance downtime.
Dual Filter Media Selection:
Polypropylene media with universal chemical resistance for conventional pretreatment; glass fiber media with high absolute efficiency for strict membrane protection requirements.
Strong Dirt Holding Capacity:
Enlarged effective filtration surface slows differential pressure growth and extends service cycles.
Cost-Effective Procurement:
Factory direct supply cuts intermediate costs and realizes shorter delivery cycles compared with imported genuine filters.
Standardized Batch Quality Control:
Complete testing procedures ensure stable performance for large engineering orders.

FAQ
Q1: Can aftermarket Pall Ultipleat Filter be directly installed in original Pall filter housings?
A1: Yes. All critical dimensions and interface structures comply with original design standards. Plug-and-play installation is supported without extra accessories or vessel adjustments.
Q2: How to choose between polypropylene media and glass fiber media for Pall Ultipleat Filter?
A2: Polypropylene media features broad chemical compatibility and suits most regular raw water pretreatment. Glass fiber media delivers higher absolute filtration efficiency, ideal for projects demanding fine particle removal and rigorous RO membrane protection.
Q3: What differential pressure value signals filter replacement?
A3: The inlet-outlet differential pressure serves as the core judgment indicator. When pressure difference reaches 25–35 PSID, filter media is severely clogged. Systems with high influent turbidity need more frequent replacement.
Q4: Can Pall Ultipleat Filter 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: What information needs confirmation before quotation?
A5: Please provide original part number, cartridge length, micron rating, required seal material, operating temperature and working medium. Our technical team will verify compatibility and provide targeted filtration solutions.
