Description
Vontron 1812 75 GPD RO Membrane
The Vontron 1812 75 GPD RO Membrane is a high‑efficiency reverse osmosis element built for compact and residential systems. Featuring a 1.8″ diameter × 12″ length (1812 format), it delivers approximately 75 gallons per day (GPD)under standard conditions with a stable salt rejection of around 97%–98%. Lenntech+1
Designed for extra‑low pressure operation, this membrane is well‑suited to homes, offices, and light commercial setups where space is tight but performance is needed.
Key Features
- Compact 1.8″×12″ (1812) size fits smaller housings and tight installations.
- Typical output ~75 GPD (~280 litres/day) under test conditions.
- Stable salt rejection ~97.5% minimum at standard test conditions.
- Operating temperature up to 45 °C and SDI requirement ≤ 5.
- Ideal for low‑salinity feed water (tap or well) and residential RO systems.

Why Choose the Vontron 1812 75 GPD RO Membrane?
If you need an efficient, compact, and high‑quality RO membrane for residential use, the Vontron 1812 75 GPD stands out. Its ultra‑low pressure design helps keep pump and energy requirements down, while its solid salt rejection ensures excellent water quality. With its 1.8″×12″ size, it integrates easily into standard small‑format RO housings—making upgrades, replacements, or new installs both simple and effective.
Installation & Maintenance Tips
-
Always pre‑treat feed water: ensure SDI ≤ 5 and free chlorine < 0.1 ppm.
-
On initial use, flush the membrane as per Vontron guidelines; discard the first tank of permeate.
-
Monitor permeate flow and rejection rate periodically—sharp drops may indicate fouling or damage.
-
Clean and replace when needed; stay within temperature, pressure and pH limits.
-
Store the membrane wet or in the recommended preservative if unused for long periods.
