FilmTec 75 GPD Reverse Osmosis Membrane

DuPont is a leader when it comes to water treatment and filtration. Their 75 GPD membrane has a 99% rejection ratio, and most other membranes cannot make that same claim. Along with meeting NSF/ANSI standards the 75 GPD DuPont (formerly Dow Chemical) membrane is hands down the best membrane for our hobby.

Up to 99% rejection Dow membrane* - NSF Certified

Compatible with all 10" RO Membrane Housings. Be sure to change the flow restrictor if you change the flow of your membrane.

Note: Brand new membranes will have a slight coating on them to help preserve the membrane until it is ready for use. It is recommended to discard all water that is produced by the new membrane for the first hour of operation.

DuPont FilmTec 75 GPD Membranes have a 96% - 99% typical stabilized salt rejection rate that can be reproduced through the following conditions:

• Source Water Pressure - 50 PSI / Membrane
• Source Water Temperature - 77°F
• Source Water TDS - 250ppm Softened Tap Water
• Recovery - 15%
• Minimum Salt Rejection - 96%
