Note : Compatibility should be confirmed by exact model, length, end cap type and sealing structure. Send a part number, cartridge photo, or housing photo for final confirmation — any one is usually enough to identify the right match.
Why Switch from OEM Pall Cartridges
- 30–50% cost savings vs genuine Pall replacement cartridges, without compromising filtration performance or service life
- Faster lead time: in-stock items ship within 2-3 days; standard production 10-14 days — vs long OEM lead times
- 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)
- Supply chain reliability: in-house production and scalable capacity vs 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 configurations. Send a housing photo if unsure — usually enough for our engineers to confirm fit.
Technical Construction Detail
The HFM Series uses 100% polypropylene construction with an outside-to-inside 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 HFU640. We recommend confirming with a part number or photo before your first order.
Q: What information do you need to confirm the right replacement?
A: Any of the following is helpful — current cartridge model, cartridge/end cap photo, housing photo, micron rating, application/fluid type, or your current differential pressure or replacement cycle. One or two of these are usually enough.
Q: Can I order a trial sample before switching my full supply chain?
A: Yes. Low MOQ of 1 carton for standard items.
Q: How long does shipping take?
A: In-stock items ship within 2-3 days. Standard production ships within 10-14 days.
Q: Can you customize length, end caps, or micron rating for a non-standard application?
A: Yes — as a direct manufacturer, EcoFiltrone can customize lengths, end-caps, and micron ratings.
