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.

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.
