AMI Membranes Product Specifications

Since the presence of free chlorine and other oxidizing agents will cause premature membrane failure, a carbon block filter should be used before this RO membrane element when filtering chlorinated water.
Performance specifications based on 500 ppm tap water, 50 psi (0.35 MPa) applied pressure, 77°F (25°C) feed water temperature, feed water pH 7-8 and 15% recovery. Element permeate flow may vary ± 15%.
*Salt Rejection shown is from internal test data.

 M-T1812A50 Compatibility Information

AMI M-T1812A50 RO is industry-standards style and will fit most RO systems using standard 50 GPD membranes. AMI 50 GPD RO membrane can also be used as direct replacement for the following membrane part numbers.  Note that this list is not complete, as 50 GPD membranes are produced under too many labels to list.  If your model is not listed, check the Membrane Dimensions drawing below against the dimensions of the element you are replacing, or contact us for assistance.

Unsure of your System or Membrane model?
You can use AMI membranes of the same flow in most RO systems by replacing the membrane housing - Available for Purchase Here
