Ecofiltrone HFL series high flow filter cartridge for Pall HFU640 replacement

Pall HFU620 Replacement Filter Cartridge

EcoFiltrone’s HFM Series High Flow Pleated Filter Cartridge is a direct drop-in replacement for the Pall HFU620, matching outer diameter, length, flow direction, micron ratings, and housing compatibility. No modification to your existing Pall-style high flow housing is required.

Send us your current part number (e.g. “Pall HFU620UY100J”) and our engineering team will confirm the equivalent EcoFiltrone model and provide a quote, typically within one business day.

Why Switch from OEM Pall Cartridges

  • 30–50% cost savings compared to purchasing genuine Pall replacement cartridges, without compromising on filtration performance or service life
  • Faster lead time: in-stock items ship within 2-3 days; standard production ships within 10-14 days — versus the long lead times common with OEM big-name brand replacements
  • No housing modification needed: seamless integration into your existing Pall-style high flow housing
  • Low MOQ for trial orders: standard items start at just 1 carton (usually 1 or 4 pieces), so you can validate performance before committing to a full changeover
  • Supply chain reliability: as a specialized manufacturer with in-house production and scalable capacity, EcoFiltrone offers more consistent lead times than sourcing through OEM distribution channels
  •  

Compatible Housings

EcoFiltrone HFM Series cartridges are compatible with standard Pall-style high flow filter housings, including common 400-series and Pall-style housing configurations that accept 20″ cartridges. If you’re unsure whether your current housing will accept the equivalent cartridge, send us a housing photo — in most cases this alone is enough for our engineers to identify the correct fit.

Technical Construction Detail

The HFM Series uses 100% polypropylene construction with an inside-to-outside flow path and a thickened polypropylene center core, allowing it to withstand higher operating differential pressures than standard high flow cartridges — extending service life under fluctuating SWRO or industrial process conditions.

FAQ

Q: Will the EcoFiltrone equivalent fit my existing Pall housing without modification?

A: In nearly all cases, yes. The HFM Series matches the outer diameter, length, and sealing structure of the original Pall HFU620, designed for seamless integration. We recommend confirming with a part number or photo before your first order.

A: Any of the following is helpful — current cartridge model, cartridge or end cap photo, housing photo, micron rating, application/fluid type, or your current differential pressure or replacement cycle. You don’t need to provide everything; one or two of these are usually enough for our team to identify the correct match.

A: Yes. We support trial orders to help you validate the transition smoothly, with a low MOQ of 1 carton for standard items.

A: In-stock items ship within 2-3 days. Standard production ships within 10-14 days.

A: Yes. As a direct manufacturer, EcoFiltrone can customize lengths, end-caps, and micron ratings to suit unique equipment requirements.
