HFU640GF200H13 Core‑Free Glass‑Fiber High‑Flow Pleated Filter Cartridge
Introduction:If you are sourcing HFU640GF200H13 high‑flow filter cartridge for heavy‑duty industrial liquid purification and RO security filtration, this drop‑in interchange consumable adopts resin‑bonded glass‑fiber pleated media with core‑free crescent‑pleat structure and inside‑to‑outside flow path. It efficiently captures suspended solids, sediment and coarse colloidal contaminants, delivering outstanding dirt‑holding capacity and ultra‑high single‑cartridge throughput. As key protective component for reverse osmosis and nanofiltration membrane systems, it mitigates membrane fouling risk and extends service cycles. Its 40‑inch large‑diameter single open‑end design cuts down cartridge quantity inside filter vessels. Supplied by Chinese original manufacturer, it provides cost‑effective replacement solution for power, petrochemical and seawater desalination projects globally.

Product Overview
HFU640GF200H13 belongs to heavy‑duty Ultipleat‑style high‑flow filter cartridge series, 40‑inch length, 6‑inch large outer diameter, core‑free crescent‑shape pleated construction, single open‑end configuration with integrated lifting tab for fast on‑site replacement. GF represents resin‑bonded glass‑fiber depth‑filtration media; 200 stands for 20 μm filtration rating; H13 is standard sealing interface. All wetted structural components are reinforced polypropylene, full thermal‑fusion welding without adhesive bonding to avoid secondary fluid contamination. Inside‑to‑outside flow path traps contaminants within pleated gaps, preventing particle re‑release toward downstream. Multiple seal options including EPDM, Buna‑N and FKM are selectable for water‑based fluid, dilute acid and alkaline working‑conditions. This replacement element can directly swap for original spare parts without modifying existing high‑flow filter housings, widely deployed in power‑plant condensate water, seawater desalination, petrochemical process liquid and large municipal water‑supply pretreatment systems.
Working Principle
HFU640GF200H13 high‑flow filter cartridge runs under inside‑to‑outside flow pattern. Un‑filtered process liquid first enters the inner cavity of filter cartridge, then flows radially outwards through multi‑layer gradient glass‑fiber pleated media. Larger solid particles are trapped in inner pleated layers, while fine impurities are captured by depth‑filtration effect inside graded glass‑fiber matrix. Unique crescent‑pleat geometry enlarges effective filtration area, slows down surface clogging and maximizes dirt‑loading capability. After purification, clean liquid flows out from outer surface of pleated media. Precision‑matched H13‑interface O‑ring seal eliminates fluid bypass risk, guaranteeing all process liquid passes through filter media to realize stable 20 μm absolute‑level filtration performance. Built‑in handling tab enables maintenance staff to finish cartridge removal and installation rapidly without special tools.
Core Technical Specifications
Core Advantages
Depth‑type glass‑fiber filtration performance:
Gradient resin‑bonded glass‑fiber media realizes excellent depth holding capacity for solid contaminants, longer service life compared with conventional PP pleated cartridges, reduces replacement frequency and on‑site maintenance workload.
Core‑free crescent‑pleat design:
Special laid‑over crescent pleating maximizes effective filtration area; core‑free construction lowers waste‑disposal cost after cartridge exhaustion, fits large‑flow heavy‑duty working scenarios.
Inside‑to‑outside flow path:
Contaminants are fully locked inside pleated folds, greatly reducing downstream re‑contamination risk, delivering stable filtrate quality under long‑time continuous operation.
Drop‑in compatible installation:
Matches dimension and H13 sealing interface of mainstream high‑flow filter vessels, no housing retrofitting needed for element swap‑out, saves system‑upgrade investment.
Competitive factory‑direct supply:
Manufactured by Chinese filtration factory. It achieves equivalent filtration performance as imported original spare parts and optimizes total procurement expenditure for global end‑users and EPC contractors.
Main Application Scenarios
Reverse osmosis pre‑filtration for industrial water‑treatment and seawater desalination projects
Power‑plant condensate water and boiler feed‑water purification treatment
Petrochemical and fine‑chemical process‑liquid pre‑treatment
Large‑scale municipal water‑supply pretreatment system

Food & beverage process‑water security filtration
Resin trap filtration for water‑treatment workshops
FAQ
Q1: Does HFU640GF200H13 fit my existing high‑flow filter housing?
A1: It adopts standard 40‑inch length, 6‑inch outer diameter, H13 sealing interface and inside‑to‑outside flow design. Please confirm housing dimension and flow‑direction requirement; most universal high‑flow filter vessels support direct installation without modification.
Q2: When should we replace HFU640GF200H13 filter cartridge?
A2: It is recommended to perform cartridge replacement when system differential pressure rises up to 2.4 bar (35 PSID). Actual service life is determined by impurity concentration of incoming raw liquid.
Q3: What is maximum working temperature for HFU640GF200H13?
A3: Max continuous operating temperature reaches 82℃. Do not operate beyond this temperature limit to avoid glass‑fiber media deformation and performance degradation.
Q4: Are other micron grades available for this GF‑series high‑flow filter?
A4: GF‑series glass‑fiber high‑flow cartridges support 1 μm,5 μm,10 μm,20 μm,40 μm,70 μm,100 μm. Custom specifications can be supported under bulk‑order condition.
Q5: What is production lead‑time for bulk HFU640GF200H13 orders?
A5: For standard‑spec filter cartridges, lead‑time is 7‑15 working days after deposit confirmation. Customized items need extra manufacturing cycle.
