Product Overview
High Flow Filter Cartridge performance standards in the R series are stated by beta ratio rather than nominal rating, and the R-series high flow cartridge sits inside Water Filter Element as the external-inlet internal-outlet variant. Water enters from outside the pleat pack and exits through the inner core, trapping contaminant on the outer face; internal PP support skeleton withstands 0.245 MPa differential pressure, and beta value exceeds 1000. OD 171 mm (6.75 in), ID 71.5 mm, 40 / 60 inch lengths, nylon end cap, Buna-N seal, max 82 ℃.

Salt Water And Boiler Condensate Scenario
On coastal RO intake and salt-water service, external-inlet flow keeps salt precipitate on the outer pleat face where it is visible at change-out, and the beta 1000 high flow element gives a quantifiable efficiency statement for boiler condensate: each particle larger than rated size has a 1000:1 retention ratio. In cosmetic and medical processing water systems, the same rating supports quality documentation, while photographic and RO pre-filtration duties use 1 to 10 μm grades. Because multiple cartridges share one housing, flow can be scaled for start-up or continuous operation, and the High Flow Filter Cartridge page lists matched housing dimensions.
Product Advantages
External inlet internal outlet geometry keeps captured contaminant on the outside face, making loading easy to inspect during vessel opening. Beta above 1000 gives a verifiable retention figure that nominal micron ratings cannot provide. The nylon end cap resists repeated handling and the Buna-N seal fits common high-flow housings. The 0.38 MPa / 21 ℃ differential rating and 2.4 Bar change-out point let operators schedule replacement on measured pressure drop rather than guesswork.
Manufacturer And Factory Strength
Our R-series production line tests each cartridge for seal seating and differential pressure before packing, and rating documentation follows multi-pass logic. The R family complements K and M series on the same platform, so a plant standardizes spares. Engineering support for coastal intake and condensate loops is available when you contact our engineering team; cross-brand housing matching references the replacement imported filter element programme.
FAQ
Q1: What does beta value above 1000 mean practically?
A1: At the rated particle size, over 1000 of every 1001 particles entering are retained; it is a measurable efficiency claim, unlike a nominal micron label.
Q2: Why external inlet instead of inside-out flow?
A1: Contaminant settles on the outer face for easy inspection and dust loading; it also suits high-flow coastal and condensate duties.
Q3: Is R series resistant to salt water corrosion?
A1: PP media and nylon end cap handle salt-water particle duty; confirm seal and housing material for continuous chloride exposure.
Q4: What differential pressure triggers change-out?
A1: Recommended change-out at 2.4 Bar @20 ℃; the working rating is 0.38 MPa @21 ℃ and 0.15 MPa @82 ℃.
Q5: Can it serve as final RO membrane protection?
A1: Yes as pre-RO polish element; choose 1 to 5 μm grade and verify SDI improvement after installation.
