FWPS Series Spun Polypropylene Cartridges | Engineered for High Capacity, Low Pressure Drop, Long Service Life

The FWPS Series from Franklin Water uses a unique three‑layer, melt‑blown polypropylene construction: largest fibres on the surface, finest fibres inside, with no chemical binders or glues. This structure provides high contaminant‐holding capacity, low pressure drop, and excellent filtration of suspended solids and particulates. Constructed from 100% polypropylene (PP) for broad chemical resistance—and certified to NSF 42 and FDA CFR Title 21 the cartridges won’t add taste, colour, or odour to your water. These filters are field proven and ideal for tradespeople working in municipal, construction, utilities and industrial sectors, and are built for tough jobs where consistent water quality and long filter life matter.

Key Features: High Capacity Filtration, Maximum Compatibility

Three‑layer melt‑blown fibre structure for high contaminant loading and long service life.
100% polypropylene media: chemical resistant, bacteria‑resistant, and free from adhesives/binders.
Compatible with potable and process water, food & beverage, RO pre‑ and post‑filtration, chemical processing.
Certified to NSF 42 and meets FDA CFR Title 21 requirements.
Long lifecycle, low pressure drop, nominal ΔP replacement at 1.5 bar (22 psi) means reduced maintenance.
