Vontron 1812 50 GPD RO Membrane – Compact 1.8″×12″
The Vontron 1812 50 GPD RO Membrane is a compact, high-quality reverse osmosis element sized 1.8″ diameter × 12″ length (designated “1812”), specifically engineered for residential or small point-of-use systems. It delivers approximately 50 gallons per day (GPD) under standard test conditions, with a stable salt rejection of around 97%. Designed for low-salinity sources such as municipal tap water or shallow wells, this membrane is ideal when space is limited but water purity remains essential.
Key Features
- Compact 1.8″ × 12″ (1812 format) — perfect for tight installations.
- Rated output: ~50 GPD (~190 L/day) under test conditions.
- Salt rejection: ~97% stable; minimum ~96% under standard conditions.
- Low-pressure design enabling integration into cost-sensitive or smaller systems.
- Suitable for residential uses: under-sink, countertop, small lab or office water purification.

Why Choose the Vontron 1812 50 GPD RO Membrane?
Opting for the Vontron 1812 50 GPD RO Membrane means choosing a space-saving, high-efficiency RO element that delivers meaningful purification in a compact format. Because it’s designed for low-salinity feed water and works at modest pressure, it’s ideal for residential installations where footprint and cost matter. The strong rejection rate ensures water quality without needing oversized systems.
Installation & Maintenance Tips
- Pre-treat feed water: ensure SDI ≤ 5 and free chlorine < 0.1 ppm to protect membrane life.
- On first use, flush the new membrane per manufacturer guidelines; discard early permeate.
- Monitor the permeate flow and salt rejection; if performance drops significantly, check for fouling, scaling or damage.
- Maintain temperature, pressure, and pH within specified limits to prolong membrane lifespan.
- If the membrane will be unused for some time, store it wet or in an approved preservative solution.
