Pall Ultipleat High Flow Water Filter – Interchangeable Aftermarket Industrial Filter Cartridge

Pall Ultipleat High Flow Water Filter is a well-known large-diameter coreless pleated filtration solution manufactured by Pall Corporation, widely used for industrial water pretreatment and RO membrane security filtration. Our interchangeable aftermarket Pall Ultipleat High Flow Water Filter strictly replicates original crescent pleat structure, inside-out flow path, dimensional tolerance and sealing specifications, supporting direct installation in standard Pall filter housings without system modification. With optional polypropylene and glass fiber gradient media, these replacement filters deliver equivalent high flow rate, stable particle removal efficiency and excellent dirt holding capacity, effectively lowering procurement costs for desalination, power generation and petrochemical projects. Many EPC clients configure HFU660GF060H13 glass fiber filter cartridge and HFU640UY045H high flow element to build reliable multi-stage water treatment filtration systems.

Product Overview

Pall Ultipleat High Flow Water Filter adopts a unique coreless large-diameter design, which greatly increases the effective filtration area compared with conventional small-diameter filter cartridges. The original HFU series has become the preferred choice for large-flow industrial water treatment globally. However, high import prices and long delivery cycles bring budget and schedule risks to plant operators and engineering contractors. Our factory produces fully compatible aftermarket replacement cartridges to solve these procurement pain points while maintaining consistent filtration performance.

Our product range covers complete specifications of Pall Ultipleat High Flow Water Filter, including 20-inch, 40-inch and 60-inch lengths. Filtration precision ranges from 1μm to 50μm. Two mainstream media are available: gradient polypropylene media for general water treatment and micro glass fiber media for high-precision fine particle interception. All filter cartridges adopt glue-free thermal fusion molding to avoid adhesive pollution and fiber shedding. Sealing options include Buna-N, EPDM and Viton to adapt to different temperature and mild acid & alkali environments. The maximum continuous working temperature reaches 82°C, and the maximum allowable differential pressure is 3.4 bar, suitable for 24-hour continuous heavy-duty operation.

Each batch of finished products undergoes dimensional inspection, bubble point efficiency test and sealing pressure resistance test to guarantee interchangeability. It effectively removes suspended solids, pipeline rust, sediment and colloidal pollutants to prevent membrane fouling and protect downstream RO/NF membrane elements, pumps and precision valves.

Filtration Working Principle

Pall Ultipleat High Flow Water Filter uses the classic inside-out filtration principle. Driven by system pressure, raw water flows into the inner cavity of the coreless filter cartridge and passes outward through multi-layer gradient pleated media. Coarse impurities such as sediment and large flocs are trapped on the inner coarse filter layer, while tiny particles and colloids that easily cause membrane pollution are deeply intercepted by the outer precision media layer.

The optimized crescent pleating structure reduces fluid dead zones and avoids media extrusion, maximizing dirt holding capacity. Pollutants are locked inside the cartridge during replacement, preventing secondary particle leakage and secondary contamination of clean water pipelines. After purification, the water enters subsequent membrane treatment units. Operators should replace cartridges promptly once inlet-outlet differential pressure rises to 25–35 PSID to restore system rated flow.

Core Competitive Advantages

• Full Drop-in Interchangeability:

• Consistent with original outer diameter, length, end cap, handle and sealing dimensions; no modification required for existing filter housings.

• Two Optional Filter Media:

• Polypropylene media with superior chemical resistance for conventional pretreatment; glass fiber media for high absolute filtration efficiency.

• High Dirt Holding Capacity:

• Larger effective filtration area extends service cycle and reduces overall maintenance frequency.

• Cost & Delivery Advantage:

• Factory direct sales eliminate intermediate links, with sufficient stock for regular models and shorter delivery time than original imports.

• Strict Quality Control:

• Complete testing procedures ensure stable and reliable performance for long-term industrial projects.
