Pall High Flow Filter Cartridge Replacement for HFU620–660
For a Pall high flow filter replacement, cross-reference the Ultipleat model to an ECOFILTRONE HFA configuration, then verify the housing interface, seal, media and operating duty before production.
Independent replacement notice: Pall and Ultipleat are used only to identify compatibility targets. ECOFILTRONE is not affiliated with, authorized by or endorsed by Pall Corporation.
HFU Model Cross-Reference
Pall’s official table supports the original model-length relationship. HFA codes that follow are ECOFILTRONE dimensional matching points; models with different suffixes, seals or interfaces are not interchangeable.
| Reference item | Confirmed value | HFA matching point | Before quotation |
|---|---|---|---|
| HFU620 | 20 inches | HFA-20 | Confirm full code, end interface and O-ring |
| HFU640 | 40 inches | HFA-40 | Confirm full code, housing drawing and duty |
| HFU660 | 60 inches | HFA-60 | Confirm full code, installed length and support |
| HFA outside diameter | 154 mm | Shared family drawing value | Check housing clearance and complete interface |
| HFA sealing format | 1 O-ring | Shared format starting point | Confirm dimensions, compression and material |
| Quotation response target | 24 hours | Current ECOFILTRONE term | Submit code, quantity and duty information |
Dimensional Compatibility Evidence: the wrong assumption can create fit risk and delay a 100-piece custom order. Market pages use both 152 mm and nominal six-inch descriptions, while the ECOFILTRONE drawing value is 154 mm.
Compatibility Gate Before Sample or Bulk Production
An interface mismatch can cause a seal failure, an installation delay or the wrong result across a 100-piece order. Matching nominal length is not necessarily matching the complete interface.
- 01Complete original HFU code and suffix
- 02Installed length and outside diameter
- 03End-cap and sealing geometry
- 04O-ring dimensions and compression
- 05Axial support and loading condition
- 06Housing photos or dimensional drawing
Request a detailed compatibility review before a sample or custom bulk release.
Seal geometry is part of fit
The NIST engineering guidance describes an elastomeric seal as a relationship between the O-ring and a groove, and the intended compression. This principle supports checking the sealing interface in its entirety as opposed to considering outside diameter in isolation.
Request a 24-hour quotation review with the original code, housing drawing, or measured element. If the documentation is incomplete, a safer bet is to do a representative sample check before a custom bulk order.
HFA Construction for Industrial Liquid Filtration
Seal and media selection can fail when the duty is guessed, because pressure behavior belongs to the complete ECOFILTRONE element-and-housing configuration. The large diameter HFA filter element, support layers, hardware, seal and micron option must be tied to the actual liquid and filter housing.

Flow pattern
Inside-to-outside flow is the documented HFA direction for the replacement format.
154mm
Outside diameter
This is the ECOFILTRONE drawing value and must be checked with the end interface and housing clearance.

Seal format
EPDM or FKM availability and the precise seal dimensions require confirmation in the quotation.
Specification questions that change the build
- Filter media and support construction
- Micron rating and the required efficiency context
- Liquid chemistry, viscosity and operating temperature
- Target flow rate and clean or terminal differential pressure
- Cleaning chemicals, change-out method and disposal constraints
ISO 3968 notes that viscosity, specific gravity, flow rate, media construction and housing design influence clean-filter differential pressure. A housing-and-element system should therefore be evaluated as an assembly.
Specify Micron Rating with an Efficiency Context
A micron number, in itself, is not a complete performance specification. A common assumption is that the number alone settles the choice, but ISO 16889 Beta context matters because an efficiency gap can leave the downstream process exposed.
Provide the process need
- Contaminant type and expected loading
- Protected equipment or downstream membrane
- Required particle size and removal objective
- Available upstream treatment
Request the product evidence
- Media and filtration rating basis
- Efficiency or Beta information when applicable
- Flow-pressure data for the quoted construction
- Material and dimensional documents available for the order
Donaldson's Beta-rating guidance gives the relationship of particle size and efficiency. Request a specific media and micron review for the application.
Industries We Serve: Application Review for Water and Process Filtration
An Ultipleat High Flow filter replacement may be considered across several liquid-filtration duties, but the application name does not select the final product. Key process constraints are feed condition, required high flow rate, downstream risk and operating envelope.
Water treatment
Industrial water, wastewater reuse, RO and UF pretreatment, seawater desalination and high-purity water preparation.
Process industries
Power generation, oil and gas, petrochemical, chemical processing, food and beverage.
Controlled environments
Pharmaceutical, life sciences and electronics industries require product-specific materials, docs and compliance review.
Escalate the review when the fluid is hazardous, high-value, temperature-sensitive, viscosity-sensitive or connected to a critical downstream process. The wrong choice can expose the downstream application.
ENGINEERING PROTOCOL
Build a Quote-Ready Compatibility File
It is a good practice to separate known facts from unmade decisions in engineering. Send known information and mark unknowns rather than speculating.
01
Identify
Provide manufacturer, full part number, current length and quantity.
02
Measure
Add element dimensions, end geometry, O-ring details and housing information.
03
Define duty
State liquid, temperature, viscosity, flow, pressure and differential-pressure limits.
04
Confirm evidence
List the drawing, material, inspection or filtration-performance documents required.
Compare Total Cost When Operating Consequences Differ
Unit price alone does not reflect labor, disposal, downtime and risk. It is not always the best comparison when technical requirements and ownership consequences differ.
01
Element and logistics
Compare element cost, order quantity, shipping and stock policy, and disposal considerations.
02
Change-out work
Review cartridge count, handling, labor time, cleaning and restart requirements.
03
Operating consequence
Consider pressure-drop behavior, service interval evidence, downtime risk and downstream process impact.
Use a detailed comparison specification here before asking suppliers to price the same defined duty.
No savings claim is made here. The checklist is a procurement framework based on general filtration total-cost factors. The trade-off matters only when site consumption, labor, disposal, pressure, downtime or service-life data differ among the actual alternatives.
CASE STUDY
Representative Sample to Reduce Fit Risk
A sample can be used to check dimensional and installation compatibility before a bulk custom commitment. It does not prove service life across the fleet and it does not replace operating validation tests.
Saudi Arabia supply example
An industrial customer evaluated a 40-inch polypropylene 5-micron sample and then placed a 300-piece shipment order. This example demonstrates a sample-to-order process only; it is not Pall-specific and no comparative performance result is claimed.
- Representative length and interface
- Confirmed media and micron requirement
- Installation check in the actual housing
- Documented buyer acceptance criteria
Request a representative test sample with the intended construction and acceptance checks.

KNOWLEDGE BASE
Frequently Asked Questions
HFA-40 is the starting point for a dimensional analysis of the 40-inch HFU640 reference. ECOFILTRONE still confirms the full original code, end geometry, O-ring dimensions, housing details and operating duty before describing the quoted cartridge as compatible.
It depends on the fluid, temperature, viscosity, contaminant, required efficiency, and existing interface. EPDM, FKM, and the appropriate micron option are confirmed in the quotation for the selected construction.
Yes. A free sample can be available with freight paid by the buyer, and trial orders are accepted; the inquiry should identify the representative model and acceptance checks.
No, diameter and length are only the first filter-cartridge checks, but an industrial replacement review also covers end geometry, the O-ring interface, tolerances and axial support.
Do not blindly take a time frame from a forum or other site. Use the process contaminant load, operating flow, differential-pressure trend, product-quality requirement and the approved change-out limit for the installed system, then compare those operating inputs at each review and reassess the timing whenever feed conditions change instead of treating a previous replacement interval as a fixed rule for every operating cycle.
Send the complete HFU code, quantity, photos or drawing, cartridge dimensions, seal information, media and micron requirement, liquid, temperature, viscosity, flow and differential-pressure conditions. Also state the material, drawing or test documents required with the order.
