FilmTec Thin Film Reverse Osmosis Filter Membranes

FilmTec Thin Film Composite Membranes are common replacements for a wide variety of Reverse Osmosis Systems. Spiral wound, thin film composite membranes offer better rejection of dissolved solids, can operate at lower pressures and produce more water faster than other types of membrane construction. Rejection rates of 99% are standard.

Available in Tap Water (Treated water supply), Chlorine filters should be used prior to the membrane for increased life. Contact us for options.

Extra Low (XLE) and Low Energy (LE) membranes can operate at lower input pressures than standard membranes.

Membrane performance is greatly affected by water temperature. Flow rates shown are based on 77° F. input water temperature. Example: (50° F. input temperature can reduce flow rates as much as 40%). Higher input temperatures will increase flow. Production rates are based on a 24 hour day.

All membranes are rated to 113° F. Rated to 600 PSI. Sizes are either 2-1/2" or 4" O.D. x length

*Low Energy Membranes.
