TRUE Thin Film Composite (TFC) Commercial Reverse Osmosis Membrane. This model is rated for 1000 Gallons per Day with a stabilized salt rejection of 98.6%. This will fit a 4 X 21 inch RO Membrane housing such as our Blue Marlin.
Membrane Replacement Tip:
- the Inlet Cap fits very tightly. A rubber mallet may be used to help remove the cap. Carefully strike the Inlet Cap at a 45-degree angle around the circumference repeatedly until you can see the first of the two o-rings. From there, you should be able to remove the cap by hand by rocking the cap up and down.
- to remove the membrane from the housing, a wrench can be used to grip the plastic inlet on the membrane.
