This Standard Size Reverse Osmosis Membrane fits in a standard membrane housing like the one on the top of the RO unit shown here which can accommodate RO membranes with capacity between 18-50 GPD. Need larger capacity? Please contact directly.

  • 500 mg/L NaCl solution

  • Water temperature: 77°F (25°C),

If you would like to change your membrane to a capacity other than what was originally in your Reverse Osmosis System, you must change the drain flow control by using a drain flow restrictor. The membrane and restrictors are sized together. Please contact us for more information so we can make the best recommendation for your system.
