Axtron 400 GPD RO Plant (Single Filmtec Membrane) – Complete 5 Stage Reverse Osmosis System
The Axtron 400 GPD RO Plant is a complete, ready-to-install 5-stage reverse osmosis system, built around a single genuine Filmtec 400 GPD membrane and a single Axtron 400 GPD Grand Forest booster pump — simpler than a multi-membrane, multi-pump setup, without sacrificing output. Produces up to 60 litres of purified water per hour.
What's Included in Axtron 400 GPD RO Plant
- 3x 20-Inch RO Slim Grey Housings (1-Inch): Reinforced polypropylene, mounted on a shared frame.

- Stage 2 – Axtron Gold Slim PPF 5 Micron Cartridge: Second-pass sediment removal, extending total sediment capacity before the membrane.
- Stage 3 – Axtron CTO Slim 20 Inch Cartridge: NSF certified carbon block filter, removes chlorine before it can damage the membrane.
- Stage 4 – FilmTec 400 GPD RO Membrane: Genuine DuPont FilmTec membrane, up to 99.6% salt rejection, fits standard 3012/3013 membrane housing.
- Stage 5 – Axtron Post Carbon T33 Cartridge: Final taste and odor polishing after the membrane.
- Axtron 400 GPD Grand Forest Booster Pump: 24V DC motor, boosts feed pressure to the membrane.
- Complete Fitting Kit: Pipe and fittings, housing key, chrome faucet, connection pipe, and power adapter.
How the 5 Stages Work Together
Raw water first passes through two sediment stages in sequence (Stages 1 & 2), removing dust, rust, and silt while extending total sediment capacity before reaching the membrane. Stage 3, the CTO carbon block, removes chlorine — critical because chlorine damages RO membranes over time. The Grand Forest booster pump then raises water pressure to the level the membrane needs, and Stage 4, the FilmTec 400 GPD membrane, removes up to 99.6% of dissolved salts, heavy metals, and other contaminants. Finally, Stage 5, the post carbon cartridge, polishes the water's taste and odor immediately before it reaches your faucet.
About the Pressure Ratings — Two Different Numbers, Not a Contradiction
The FilmTec 400 GPD membrane carries a maximum structural pressure rating of 600 PSI — but that's a ceiling the membrane can withstand, not the pressure your system actually runs at. The included Grand Forest booster pump operates up to 130 PSI, which is what actually drives water through the membrane in this system. The 600 PSI figure tells you the membrane has plenty of headroom; the 130 PSI figure tells you what the system delivers.
Real Output: 400 GPD Rating vs. Practical Litres Per Hour
"400 GPD" is the membrane's nameplate rating under standard test conditions, not a guaranteed 24-hour output figure. In practical use with the included booster pump, this system produces up to 120 litres per hour while actively running, typically filling a storage tank rather than running continuously.
Why Choose This Axtron 400 GPD RO Plant System
- Genuine Filmtec Membrane: DuPont FilmTec technology, not a generic membrane — 99.6% salt rejection.
- Simpler Than Multi-Membrane Setups: One membrane, one pump — fewer components to maintain and replace compared to a 4-membrane, 2-pump configuration.
- Double Sediment Protection: Two sediment stages ahead of the carbon and membrane stages mean less fouling and longer component life.
- Complete, Ready-to-Install Kit: Frame, all cartridges, membrane, booster pump, faucet, and fittings — nothing separate to source.
- Built for Pakistani Water Conditions: Double sediment filtration handles the heavier particulate loads common in tanker-supplied or borewell water.
Where This Axtron 400 GPD RO Plant Fits
- Homes and Offices Needing Higher RO Output: 60L/hour practical output suits larger households, small offices, and light commercial use.
- Hospitals, Schools, Labs, and Similar Institutions: The FilmTec membrane is rated for exactly these semi-commercial applications.
- Tanker or Borewell Water: Double sediment pre-filtration handles the heavier particulate loads common in these sources.
- Customers Who Prefer Fewer Moving Parts: A single membrane and single pump is simpler to maintain than a multi-membrane, multi-pump system.

Frequently Asked Questions
Q1: How is this different from your other 400 GPD RO plant?
Your existing "2 Pumps 4 Membranes" plant uses four generic 100 GPD membranes and two pumps. This system uses a single genuine Filmtec 400 GPD membrane and a single Grand Forest booster pump — a simpler configuration with a name-brand membrane.
Q2: What does "400 GPD" mean, and does this system really produce that much?
400 GPD is the membrane's nameplate rating under standard lab test conditions, not a guaranteed 24-hour output figure. In practical use with the included booster pump, this system produces up to 60 litres per hour while actively running.
Q3: Why does the membrane say 600 PSI but the pump only goes up to 130 PSI?
600 PSI is the membrane's maximum structural rating — how much pressure it can safely withstand. The pump's 130 PSI is what actually drives the system. There's no contradiction; the membrane simply has more pressure tolerance than the system uses.
Q4: What's included in this RO plant?
The complete frame with 3 housings, two sediment cartridges, one carbon block cartridge, a FilmTec 400 GPD membrane, a post carbon cartridge, an Axtron 400 GPD Grand Forest booster pump, plus faucet, pipes, fittings, and housing key.
Q5: Is the membrane a genuine Filmtec membrane?
Yes — FilmTec membranes are manufactured by DuPont, USA.
Q6: How long does the membrane last?
18–24 months with proper pre-filtration and maintenance.
Q7: Is this suitable for tanker or borewell water?
Yes — the double sediment pre-filtration stage is well suited to the higher particulate loads common in tanker-supplied or borewell water.
Q8: Is delivery available across Pakistan?
Yes, Axtron Pakistan offers nationwide delivery, including Karachi, Lahore, Islamabad, Rawalpindi, Faisalabad, and Multan.
