HFU620GF100H13 Pall Ultipleat High Flow Filter Element: Glass‑Fiber Absolute‑Rated Large‑Diameter Pleated Consumable

For Middle‑East EPC contractors, power‑plant operators and water‑treatment integrators, high‑temperature process fluid and strict particle‑removal requirements put forward high standards for security filter consumables. Polypropylene high‑flow cartridges cannot satisfy partial high‑temperature working‑condition requirements, while HFU620GF100H13 Pall filter element fills this gap with glass‑fiber absolute‑rated media, belonging to classic Ultipleat High‑Flow product line.

Traditional small‑size glass‑fiber cartridges need large quantity under high‑flow conditions, bringing bulky housings and heavy maintenance workload. HFU620GF100H13 adopts 6‑inch large‑diameter core‑less pleated structure; single‑element high throughput greatly reduces required cartridge quantity and equipment footprint. Inside‑to‑outside flow traps contaminants inside the element, avoiding secondary pollution during cartridge replacement. Interchangeable aftermarket replacement elements keep consistent dimension, sealing interface and filtration efficiency with OEM parts, helping local projects cut procurement cost and shorten spare‑part lead‑time for continuous‑run production facilities.

Working Principle

HFU620GF100H13 applies inside‑to‑outside flow direction. Raw liquid flows from outer pleated surface inward through multi‑layer resin‑bonded glass‑fiber media. Large‑size sediment, rust and suspended flocs are captured on outer pleat layers; fine solid particles are reliably intercepted by inner absolute‑rated glass‑fiber media, achieving graded depth‑type filtration and maximizing dirt‑holding capacity.

Unique laid‑over crescent pleat geometry optimizes fluid distribution and avoids local media overloading. Core‑less design eliminates internal dead‑zone. Integrated lifting handle facilitates quick disassembly. Buna‑N (H13 code) O‑ring sealing prevents fluid bypass risk. As contaminants accumulate, inlet‑outlet differential pressure rises. Operators should replace filter element when differential pressure reaches recommended value. It is installed upstream of reverse osmosis, heat‑exchanger and precision process equipment, protecting high‑value downstream components from particle abrasion and fouling.

Core Product Performance & Advantages

Absolute‑rated glass‑fiber media with high temperature resistance Resin‑bonded glass‑fiber material realizes 10 μm absolute filtration efficiency, stable particle interception performance, suitable for working conditions up to 121 ℃. It can handle high‑temperature condensate water and hot process fluid scenarios which polypropylene cartridges cannot withstand.

Large‑diameter core‑less high‑flow structure 6‑inch large‑diameter pleated design provides huge filtration area. One HFU620GF100H13 element can replace multiple standard‑size filter cartridges, reducing element quantity, shrinking filter housing size and lowering initial equipment investment for skid‑mounted systems.

High dirt‑holding capacity for extended service interval Multi‑layer gradient glass‑fiber structure holds large contaminant load, slows pressure‑drop rising speed. Longer service cycle reduces cartridge consumption, shutdown frequency and on‑site labor cost for 24‑hour continuous‑run industrial plants.

Inside‑to‑outside flow avoids secondary contamination Contaminants remain inside filter element during operation and replacement. No particle falling‑off into downstream pipeline when taking out clogged cartridge, effectively guarantee filtrate quality stability. Built‑in handle supports fast change‑out without special tools.

Reliable sealing and wide chemical adaptability Buna‑N O‑ring sealing eliminates bypass leakage risk. Glass‑fiber media matches aqueous medium, partial organic solvent, glycol and cooling liquid. Interchangeable replacement elements strictly follow original dimension and sealing interface, realizing direct drop‑in installation without modifying existing housings.

FAQ

Q1: What is the difference between HFU620GF100H13 glass‑fiber element and PP‑type Ultipleat cartridges?

A: GF glass‑fiber version can resist maximum temperature up to 121 ℃, fit for high‑temperature condensate and hot process fluid. PP media max temperature is 82 ℃, mainly for normal‑temperature water treatment. Both adopt core‑less large‑diameter high‑flow structure.

Q2: What does suffix H13 stand for in HFU620GF100H13?

A: H13 represents Buna‑N (NBR) O‑ring sealing material, suitable for water, general oil and partial solvent medium. Select other sealing codes (H, J etc.) for special chemical working‑conditions.

Q3: When shall HFU620GF100H13 filter element be replaced?

A: Replace element when system differential pressure reaches recommended 2.4 bar. Do not run beyond maximum differential pressure, to prevent media damage and particle breakthrough.

Q4: Can HFU620GF100H13 be used for RO security pre‑filtration?

A: Yes, its 10 μm absolute‑rated glass‑fiber media provides reliable security protection for reverse osmosis membranes, widely adopted in desalination and industrial water‑treatment projects.

Q5: Can you provide interchangeable replacement HFU620GF100H13 filter elements for large‑scale Middle‑East projects?

A: Yes. Our interchangeable elements copy original dimension, glass‑fiber media performance and sealing structure. We can provide batch test reports and bulk‑order quotation services for industrial purchasers.
