The Pall HFU640UY100J is part of Pall's Ultipleat High Flow (Profile II) family — large-format pleated elements built for high throughput in a single housing. If you operate this element and are reviewing your filter supply, this guide explains what the part number means and how to source a compatible replacement.
How to read the part number
Pall's HFU high-flow codes follow a consistent logic. Reading HFU6-40-UY-100-J segment by segment:
| Segment | Meaning |
|---|---|
| HFU | High Flow Ultipleat series |
| 6 | Nominal 6-inch diameter class |
| 40 | Nominal 40-inch length |
| UY | Media / construction code |
| 100 | Micron rating indicator |
| J | End-cap / interface configuration |
Understanding the code helps you confirm that a replacement matches on the dimensions and interface that actually determine fit: outer diameter, length and end-cap geometry.
Typical applications
High-flow elements in this class are used where large liquid volumes must be filtered with a small housing footprint — for example in oil & gas processing such as amine (MDEA) treatment, condensate and produced-water filtration. The pleated Profile II geometry maximises surface area, which extends service life between change-outs.
Compatible R+F replacement
R+F FilterElements manufactures a high-flow element engineered to fit the same housings as the Pall HFU640UY100J. The fit is dimensionally verified against the original element's diameter, length and interface. You can review the dedicated part page here: Replacement for HFU640UY100J.
Because the replacement drops into your existing housing, no hardware changes are required — the switch is simply a change of consumable element at the next scheduled service.
