Upgrade your home water purification system with the Black Max Thin Film Composite (TFC) membrane, engineered specifically for residential reverse osmosis units. Delivering a robust 75 gallons per day (GPD) of crystal-clear, purified water, this membrane ensures your household enjoys consistently fresh and safe drinking water. Compatible with all Franklin Water Treatment Vectapure Systems and most standard residential membrane housings, it offers a reliable solution to enhance your water quality.
Important: This membrane is not compatible with the newer V360 and NX systems, which require encapsulated membranes. Please check our other listings for membranes designed for those models.
How It Works
The Black Max membrane features an advanced multilayer design, with thin films spirally wrapped around a central tube, maximizing filtration efficiency. As water flows over the membrane surface:
- Pure water molecules seamlessly pass through and collect inside the central tube, providing you with clean, fresh water.
- Minerals, contaminants, and impurities are effectively blocked and directed to the drain, preventing them from entering your water supply.
