HFU620GF100H13 Pall – Ultipleat High Flow Glass Fiber Filter Cartridge

HFU620GF100H13 Pall – Ultipleat High Flow Glass Fiber Filter Cartridge

HFU620GF100H13 Pall is a coreless wide-diameter glass fiber high flow filter cartridge belonging to Pall Ultipleat HFU series, widely applied in industrial raw water pretreatment, high-temperature process water filtration and RO membrane security filtration systems. Our interchangeable aftermarket HFU620GF100H13 fully replicates the original crescent pleat layout, single open-end structure, integrated lifting handle and H13 U-cup sealing dimensions, supporting direct plug-and-play installation inside standard Pall high flow filter housings without any equipment modification. Adopting resin-bonded glass fiber GF media, this replacement cartridge provides stable ultra-high flow rate, reliable 10μm absolute particle retention rate and excellent dust holding capacity. Most water treatment EPC partners match HFU640GF200H13 filter cartridge and HFU620UY400JU filter element with HFU620GF100H13 to build stable and efficient multi-stage industrial water purification systems.

Product Overview

HFU620GF100H13 Pall features the classic Ultipleat core-free 6-inch wide-diameter crescent pleated design with standard inside-out flow path. Optimized arc pleat structure effectively eliminates fluid dead zones and greatly increases the effective filtration area, enabling single-cartridge high-flow output and significantly reducing the total number of filter cartridges and filter vessel investment. As a 20-inch short-type high-precision glass fiber filter cartridge with 10μm absolute filtration accuracy, it is specially designed for high-temperature and high-precision industrial water treatment scenarios, widely used in seawater desalination, power plant condensate polishing, petrochemical high-temperature process water and municipal water supply projects.

Genuine Pall HFU620GF100H13 cartridges have stable filtering performance but suffer from high procurement costs and long import delivery cycles, which easily cause project progress delays and budget pressure for end users and engineering contractors. Our factory-produced interchangeable HFU620GF100H13 replacement cartridges strictly follow original dimensional standards and technical parameters, with performance fully reaching the original level, providing cost-effective and fast-supply filtering solutions for global industrial water treatment projects.

Core specifications of HFU620GF100H13: 6 inch outer diameter, 20 inch nominal length, 10μm absolute filtration rating, GF resin-bonded glass fiber media, H13 NBR U-cup sealing structure. End caps, support skeleton and outer protective layer are all made of reinforced polypropylene. The whole cartridge adopts full thermal fusion molding process without any adhesive, effectively avoiding fiber shedding and secondary fluid contamination. Compared with conventional PP filter media, glass fiber media has more uniform pore structure, higher filtration efficiency and excellent high-temperature resistance. The maximum continuous operating temperature reaches 121°C, and the maximum allowable differential pressure is up to 3.4 bar, which can adapt to 24/7 long-term continuous industrial heavy-duty operation.

Every batch of HFU620GF100H13 cartridges undergoes strict dimensional tolerance inspection, bubble point efficiency test and pressure tightness test to ensure 100% seamless interchangeability with original equipment. It can efficiently intercept suspended solids, pipeline rust, sediment, fine colloids and tiny impurity particles, effectively reduce RO membrane fouling and scaling risks, and provide reliable precision protection for downstream membrane modules, water pumps and precision regulating valves.

Filtration Working Principle

HFU620GF100H13 Pall follows the mature inside-out gradient depth filtration principle. Driven by system operating pressure, raw water enters the inner cavity of the coreless filter cartridge and penetrates outward layer by layer through multi-layer gradient glass fiber pleated media.

The gradient structural design realizes hierarchical interception: large particles such as sediment and flocs are trapped by the inner coarse pleated layer, while fine colloids and micro-particles that easily cause membrane blockage are deeply intercepted by the outer high-precision glass fiber layer. The unique crescent pleat arrangement prevents media compression under high pressure, maintains stable filtration area and flow rate, and maximizes dirt holding capacity. All intercepted pollutants are locked inside the cartridge, avoiding secondary leakage and clean water pipeline pollution during replacement. When the inlet-outlet differential pressure rises to 25–35 PSID, the filter element reaches the dirt holding saturation limit and needs to be replaced in time to restore the system’s rated flow and filtration accuracy.

FAQ

Q1: Is HFU620GF100H13 fully compatible with original Pall filter housings?

A1: Yes. All structural dimensions, interface positions and H13 sealing specifications are strictly benchmarked against the original factory standards, supporting plug-and-play installation without any modification.

Q2: What is the meaning of each code of HFU620GF100H13?

A2: HFU = Ultipleat High Flow series; 620 = 6 inch OD, 20 inch length; GF = resin bonded glass fiber media; 100 = 10 micron absolute precision; H13 = NBR U-cup sealing structure.

Q3: When is the best replacement time for HFU620GF100H13?

A3: Take system inlet-outlet differential pressure as the standard. Replace in time when the pressure difference reaches 25–35 PSID. High turbidity and high-temperature working conditions require shorter replacement intervals.

Q4: Can the glass fiber HFU620GF100H13 cartridge be cleaned and reused?

A4: It is a disposable depth filter cartridge. Fine impurity particles will penetrate into the deep pores of the glass fiber media. Conventional backwashing cannot restore the original filtration efficiency, so disposable replacement is recommended.

Q5: Are customized specifications available for HFU620 series?

A5: Yes. We support customized micron accuracy, sealing type and special material configuration for HFU620 series. Optional precision: 1μm, 4.5μm, 6μm, 10μm, 20μm; optional seals: H13, J, H, EPDM, Viton. Please provide working conditions for accurate quotation.
