Flowmatic Systems: Engineered Water Filtration for RV & Marine Use

When clean, safe drinking water is a non-negotiable — whether you're hooked up at a campground or dockside on the water — Flowmatic Systems delivers reliable, purpose-built solutions through their well-regarded Flow-Pur product line. Flowmatic Systems Inc. has earned its reputation as a go-to manufacturer of water filters and treatment systems specifically designed for the recreational vehicle and marine industries, where water source quality can vary wildly and compact, dependable filtration is essential.

The Flow-Pur Product Line

Flowmatic's Flow-Pur lineup spans a range of filtration solutions tailored to different use cases and levels of protection. From entry-level inline filters for the weekend camper to multi-stage exterior housing systems for full-time RVers and boaters, there's a Flow-Pur filter built for the job.

• Flow-Pur Economical Exterior In-Line Filter (FP12GE-RV): A straightforward inline filter designed for occasional campers, connecting directly to a fresh water supply hose via standard garden hose fittings — no special tools or complex installation required.
• Flow-Pur Single Exterior Water Filter (POE12GHGACB): A canister-style system that mounts to the exterior of an RV or boat and includes a Carbon Block Cartridge (#8) designed to reduce chlorine, sediment, unpleasant taste, odors, and VOCs at a flow rate of 2.5 GPM.
• Flow-Pur Ultimate Duo Exterior Water Filter (POE12DSA1KDF): A dual-canister setup that pairs a sediment pre-filter with a GAC/KDF cartridge for two-stage filtration. The GAC/KDF filter (#5) actively removes inorganic contaminants before they reach the carbon bed, protecting it from bacterial fouling and extending overall filter life.
• Flow-Pur Inline Filters with Quick Connect: Models like the FP10GKC and FP10GKJ feature quick-connect fittings (including John Guest-compatible connectors) that make cartridge swaps faster and cleaner in tight spaces.

Filter Technology That Goes Beyond Basic Sediment Removal

What sets Flowmatic's Flow-Pur cartridges apart is their use of multiple filtration media suited to real-world water challenges. The GAC/KDF replacement cartridge, for instance, is NSF Certified and uses a granular activated carbon and KDF media combination that not only reduces chlorine, taste, and odors, but also inhibits bacteria growth — a critical feature when a system sits unused between camping trips. Coconut shell carbon block cartridges (such as the WCBCS-975RV) provide dense, channeling-resistant filtration that is effective for both interior and exterior filter systems.

Replacement cartridges are widely available and many Flow-Pur cartridges are designed to interchange with other major brands' #5 and #8 housings, making Flowmatic a practical upgrade path regardless of the existing system on your rig or vessel.
