Ultipleat High Flow Filters | Pall Large‑Diameter Coreless Pleated Filter Cartridges

Ultipleat High Flow Filters | Pall Large‑Diameter Coreless Pleated Filter Cartridges

Ultipleat High Flow Filters are well‑known coreless single‑open‑end pleated filter cartridges manufactured by Pall, adopting unique crescent‑shaped pleat geometry and inside‑to‑outside flow pattern for heavy‑duty industrial high‑flow water treatment. With 6‑inch large diameter and optional lengths of 20/40/60/80 inch, one single Ultipleat high flow filter can reach up to 500 gpm flow rate, greatly reducing cartridge quantity and housing footprint for RO pre‑filtration, desalination and power‑generation projects. Our aftermarket equivalent Ultipleat High Flow Filters keep full form‑fit‑function compatibility with original Pall filter housings. Many industrial water‑treatment projects combine HFU660CAS010JUW filter cartridge and RTM41HF050E filter element with Ultipleat High Flow Filters to complete multi‑stage purification for chemical, municipal and food‑beverage industries.

Product Overview

Ultipleat High Flow Filters represent Pall’s flagship large‑diameter high‑flow cartridge series. Different from traditional central‑core filter elements, this series applies coreless all‑plastic construction with exclusive crescent‑shaped pleat layout to maximize effective filtration area. Liquid flows from inner pleated layer toward outer housing side, trapping all contaminants inside the filter cartridge, which avoids secondary pollution during element replacement. Available media options include polypropylene HDC® II, Profile® depth media and Ultipor® GF glass fiber media, covering broad micron ratings to satisfy coarse pre‑filtration and fine polishing requirements.

Original Pall Ultipleat High Flow Filters deliver stable performance for global heavy‑duty facilities, yet end‑users frequently face high original‑equipment cost and long international lead‑time. As a professional aftermarket filter manufacturer, our replacement Ultipleat High Flow Filters strictly copy OEM dimension, pleat geometry, sealing interface and particle retention efficiency. Every batch passes bubble‑point test and pressure‑tightness inspection before delivery for worldwide water‑treatment integrators and end‑users.

Core specifications of replacement Ultipleat High Flow Filters: Coreless single open‑end structure; 6‑inch(152.4 mm) outer diameter; available lengths:20/40/60/80 inch; inside‑to‑outside flow direction; media: PP HDC II, Profile, glass fiber; O‑ring choices: Nitrile, EPR, FKM, Silicone; integrated lifting handle for easy replacement; max operating temperature varies with filter media; recommended replacement differential pressure:2.4 bar; fully interchangeable with Pall Ultipleat series filter housings.

Replacement Ultipleat High Flow Filters can directly fit original Pall filter housings without modification. It efficiently captures sediment, suspended solids and colloidal impurities, protecting expensive RO membrane modules and other precision process equipment from particle damage.

Filtration Working Principle

Ultipleat High Flow Filters adopt inside‑to‑outside gradient depth‑surface combined filtration principle. Raw water enters from inner core side and flows outward through multi‑layer crescent‑pleated filter media. Large‑size impurities are trapped in inner‑layer pleats, while fine particles and colloids are intercepted by outer gradient fiber layers. The unique crescent‑shaped pleat design prevents pleat bunching and collapsing under long‑term high‑flow running, maintaining stable low‑pressure‑drop performance. Coreless all‑plastic structure reduces waste volume after use. When inlet‑outlet differential pressure rises to 2.4 bar, the filter reaches dirt‑holding saturation and needs timely replacement to guarantee stable effluent‑water quality.

Core Competitive Advantages

Unique Crescent‑Shaped Pleat Geometry: 

Optimized pleat structure avoids media bunching, maximizes filtration area for high throughput and long service life.

Coreless Large‑Diameter Design: 

6‑inch OD coreless construction, fewer cartridges required, shrink filter housing volume up to 50%, cut installation and maintenance cost.

Inside‑to‑Outside Flow Pattern: 

Contaminants stay inside filter cartridge, prevent secondary contamination during filter‑change‑out procedure.

Rich Media & Micron Options: 

Polypropylene, glass‑fiber media for different chemical compatibility demands, absolute‑rated performance for repeatable filtration results.

Integrated Lifting‑Handle: 

Simple pull‑out operation, reduce direct contact with contaminated filter media during maintenance.

Drop‑in OEM Interchange: 

Strict dimensional tolerance, fully compatible with original Pall Ultipleat filter housings with no modification needed.

Main Application Scenarios

Seawater and brackish water desalination RO security pre‑filtration systems

Power plant boiler make‑up water and condensate large‑volume water‑treatment

Petrochemical process water, injection‑water and industrial circulating‑water purification

Food & beverage production process‑water and bottled‑water pretreatment filtration

Electronics‑semiconductor ultrapure‑water pretreatment high‑flow filtration projects

Large‑scale municipal water‑supply and industrial raw‑water treatment plants

FAQ

Q1: What are Ultipleat High Flow Filters?

A1: Ultipleat High Flow Filters are Pall coreless 6‑inch large‑diameter single‑open‑end pleated cartridges with crescent‑shaped pleats, inside‑to‑outside flow for heavy‑duty high‑flow industrial water‑treatment.

Q2: What flow direction do Ultipleat High Flow Filters adopt?

A2: Inside‑to‑outside flow pattern, raw water flows from inner core outward, all contaminants are trapped inside filter element.

Q3: When should Ultipleat High Flow Filters be replaced?

A3: Replace when inlet‑outlet differential pressure reaches 2.4 bar. High‑turbidity feed‑water will shorten service life accordingly.

Q4: Can Ultipleat High Flow Filters be cleaned and reused?

A4: They belong to disposable depth‑pleated consumables. Fine impurities penetrate deep into filter media, backwashing cannot restore full filtration performance, disposable replacement is recommended.

Q5: What housing fits Ultipleat High Flow Filters?

A5: It matches Pall Ultipleat series filter housings; our aftermarket replacement version can be directly installed without modification.
