About RP-U17
RP-U17 is a twin-housing high-flow pre-filter built around a 10-inch large-diameter cartridge. The main model pairs a PP + carbon + 60 g KDF cartridge with a grooved PP sediment cartridge in a food-grade reinforced PP housing. Flow is ≥45.42 L/min at 0.2 MPa through 1-inch pipes, chlorine removal is ≥50% at 15 L/min with a 2 ±0.3 ppm feed, and the reference service volume is ≥189 tonnes (source test water). Two further pre-filter options are available — see Variants below.
Why buyers choose it
- High flow of ≥45.42 L/min at 0.2 MPa through 1-inch pipes.
- PP + carbon + 60 g KDF cartridge plus grooved PP sediment cartridge, in a food-grade reinforced PP housing.
- Chlorine removal ≥50% at 15 L/min with a 2 ±0.3 ppm feed.
- Reference service volume of ≥189 tonnes (source test water).
Best for
- Whole-house or point-of-entry pre-filtration ahead of an under-sink system.
- Buyers who need a high-flow pre-filter with KDF and sediment cartridges.
- Brands that want a pre-filter family with three options to quote from.
Frequently asked questions
What is the minimum order quantity?
The first order is 200 units per model, and reorders are 500 units.
Can I order a sample before a bulk order?

Which pre-filter variant should I choose?
Quote as RP-U17 and specify the variant: twin-housing KDF pre-filter, folding PP + carbon fibre variant, or grooved PP cotton variant. The folding PP + carbon fibre variant is a two-stage, single-housing pre-filter at 33.3 L/min, 30000 L service volume with a cartridge life of 1–2 years; the grooved PP cotton variant is listed with parameters only and has no standalone product photograph.
