HFU620CAS010JUW Core‑Less High‑Flow Pleated Filter Cartridge
Introduction:If you are sourcing HFU620CAS010JUW high flow filter cartridge for industrial RO pre‑treatment and power‑plant water purification, this drop‑in interchange consumable adopts CAS‑series absolute‑rated pleated media with inside‑to‑outside flow path. It effectively captures suspended solids, fine particles and colloidal contaminants, delivering outstanding dirt‑holding capacity and stable high‑flux performance. As critical protective filter element ahead of reverse osmosis membranes, it reduces membrane fouling risk and extends operational service cycles. Its 20‑inch large‑diameter core‑free single open‑end design lowers required cartridge quantity inside filter vessels. As cost‑effective replacement supplied by Chinese manufacturer, it fits heavy‑duty water‑treatment projects across global markets.

Product Overview
HFU620CAS010JUW is 20‑inch core‑free Ultipleat‑style high flow pleated filter cartridge, widely deployed for industrial liquid security filtration. It features 6‑inch large outer diameter, special crescent‑shape pleated structure without inner support core, single open‑end configuration with lifting tab for quick field replacement. CAS‑grade absolute‑efficiency filter media ensures stable 10‑μm particle retention performance. All wetted structural components adopt reinforced polypropylene material, thermal‑fusion welding technology without adhesive bonding to avoid secondary liquid contamination. JUW sealing configuration matches standard high‑flow filter housings. Multiple seal material options including EPDM, Buna‑N and FKM are available to adapt to water‑based fluid, dilute acid and alkaline working conditions. This replacement element can directly swap with original spare parts without equipment modification, popular for power plant condensate water, seawater desalination and petrochemical water treatment systems.
Working Principle
HFU620CAS010JUW high flow filter cartridge applies inside‑to‑outside flow mode for liquid purification. Unfiltered liquid flows into the inner cavity of the filter cartridge first, then passes outward through multi‑layer gradient pleated filter media. Solid impurities are trapped inside the pleated gaps, preventing contaminants from escaping toward downstream side. Unique crescent pleating optimizes available filtration area and slows down surface blockage progress, greatly improving dirt‑loading capability. After full filtration, clean liquid flows out from outer surface of the cartridge. Precision‑matched O‑ring seal eliminates fluid bypass risk, making sure all process liquid passes through filter media to achieve absolute‑rated filtration effect. Built‑in handling tab helps maintenance operators finish element removal and installation rapidly without special tools.
Core Technical Specifications
Core Advantages
Absolute‑rated 10μm filtration:
CAS graded pleated media delivers stable absolute particle retention performance, perfectly meets strict security pre‑filtration requirement for RO and NF membrane systems.
Core‑less crescent pleated design:
Special crescent‑shaped pleating maximizes effective filtration area, enhances dirt‑holding capacity and extends service life; core‑free construction reduces waste disposal cost after use.
Inside‑to‑outside flow path:
Contaminants are fully retained inside filter pleats, avoiding downstream re‑contamination risk; stable performance under long‑time continuous working status.
Drop‑in compatible installation:
Exact dimension and sealing interface match mainstream high‑flow filter housings. No modification is needed during cartridge swap‑out, cutting on‑site maintenance labor cost.
Competitive factory‑direct supply:
Produced by Chinese filter manufacturer. It achieves equivalent filtration performance as imported original spare parts and optimizes total procurement expense for global industrial end‑users and engineering 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
Steel‑plant circulating water filtration
Food & beverage process‑water security filtration
Resin trap filtration for water‑treatment workshops
FAQ
Q1: Does HFU620CAS010JUW fit my existing high‑flow filter housing?
A1: It adopts standard 20‑inch, 6‑inch outer diameter, JUW sealing interface and inside‑to‑outside flow design. Please confirm housing dimension and flow direction requirement, most universal high‑flow vessels support direct installation without retrofitting.
Q2: When shall we replace HFU620CAS010JUW filter cartridge?
A2: It is recommended to carry out replacement when system differential pressure rises up to 2.4 bar (35 PSID). Actual service life is subject to impurity concentration of incoming raw liquid.
Q3: What is the maximum working temperature for HFU620CAS010JUW?
A3: Max continuous operating temperature reaches 79℃. Do not run beyond this temperature limit to prevent pleated media deformation and performance degradation.
Q4: Are other micron grades available for this CAS‑series high‑flow filter?
A4: CAS‑series supports 1 μm,5 μm,10 μm,20 μm absolute‑rated specifications. Custom micron options can be supported for bulk‑order projects.
Q5: What is production lead‑time for bulk HFU620CAS010JUW orders?
A5: For standard‑spec filter cartridges, lead‑time is 7‑15 working days upon deposit confirmation. Customized requirements need extra manufacturing cycle.
