1812 50 GPD FilmTec – Compact and Efficient RO Membrane
The 1812 50 GPD FilmTec membrane is perfect for home reverse osmosis systems that need reliable water flow and effective contaminant removal. Because it delivers 50 gallons per day (about 190 litres), it fits most standard 1812 housings. In addition, this membrane works well as both a replacement and an upgrade for residential systems. As a result, you get clean water with minimal maintenance.
Key Features
- Rated Output: 50 GPD (~190 L/day)
- Salt Rejection: Up to 98–99%
- Membrane Type: Spiral-wound thin-film composite (TFC)
- Size: ~298 mm × 44.5 mm (fits standard 1812 housings)
- Feed Water: Tap or pre-treated borehole water
- Compact Design: Ideal for small under-sink RO systems
Furthermore, the membrane’s thin-film composite technology ensures durability and high efficiency.
Operating Limits
To maintain performance:
- Maximum Temperature: 45 °C
- Maximum Pressure: 150 psi
- Maximum Cleaning Pressure: 300 psi
- Free Chlorine Tolerance: < 0.1 ppm (carbon pre-filter recommended)
- pH Range: Continuous 2–11; short-term cleaning 1–13
- Maximum SDI: 5
In addition, following these limits prevents membrane damage and ensures a longer lifespan.
Benefits
The 1812 50 GPD FilmTec membrane provides steady flow and excellent water quality. Moreover, it improves taste and clarity. Therefore, it is ideal for households and small offices. Additionally, installation is simple, and the compact size fits most RO housings. Finally, it protects against common contaminants, giving you peace of mind.
Installation & Maintenance
- Confirm your RO system supports 1812 membranes.
- First, install sediment and carbon pre-filters to protect the membrane.
- Insert the membrane in the correct flow direction.
- Next, flush the system to remove preservatives.
- Monitor TDS and flow; replace the membrane if performance drops.
- Finally, maintain proper pressure, temperature, and low chlorine levels for best results.
Applications
- Home under-sink RO systems
- Small office drinking water units
- Replacement for standard 1812 membrane housings
