Description
STPFA High Flow Water Filter Element
The WIRES STPFA high-flow filter element features a large 6-inch (152.4 mm) diameter pleated design that delivers dramatically greater effective filtration area compared to standard cartridges. This results in higher flow rates, longer service life, and fewer element change-outs — making it a cost-effective choice for high-purity water treatment and industrial liquid filtration applications. The flow direction runs from outside to inside, with the support structure available as either integral polypropylene or polyester mesh.
Key Features
- Large diameter high-flow design: 6-inch outer diameter provides significantly greater filtration area than standard cartridges, enabling high flow rates with low differential pressure.
- Hydrophilic membrane media: No pre-wetting required — the filter element is ready for immediate use, reducing commissioning time and labor costs.
- Integral support core: Polypropylene inner support structure provides high strength, dimensional stability, and long service life even under demanding process conditions.
- Thermal sealed construction: End caps and media are thermally welded to ensure a reliable, leak-free seal without adhesive binders that could contaminate the process fluid.
- Direct housing compatibility: Designed to fit existing standard high-flow filter housings without modification or re-piping.

Cross Reference
The STPFA series is designed as a direct replacement for standard 6-inch high-flow filter cartridges used in RO pretreatment housings. It is interchangeable with cartridges from major manufacturers including 3M (High Flow series), Pall (Ultipleat), Pentair, and other comparable large-diameter housings. Always verify by housing model and required flow rate before ordering. Custom dimensions and end-cap configurations are available on request.
Applications
- RO system pretreatment and reverse osmosis protection
- Seawater desalination pre-filtration
- Ultrapure water filtration for microelectronics and pharmaceutical applications
- Power plant condensate and cooling water filtration
