75 gpd (gallon per day) BlackMax TFC (thin film composite) Residential Reverse Osmosis Membrane by Waterite.

Part # BME1812R75

Fits all Waterite Vectapure and WR series Reverse Osmosis systems and most standard residential membrane housings. The only system this doesnt fit is the new V360 and NX system whichs use encapsulated membranes, see our other listings for those parts.

If your system already used a 75 gpd membrane you can simply replace the membrane but if you are changing the size of the membrane say from a 36 gpd to a 75 gpd rated membrane then you will also need to change the flow control valve to match the new membrane. See our Reverse Osmosis parts section for your flow control valve if needed.

Note: Often the small openings or tubes in a flow control valve can become plugged slowing the pure water production rate, it is advisable to replace this part when replacing your membrane.

The matching flow control valve to this 75 gpd rated membrane is a 500ml flow restrictor part # FR500EZ, one can also use anything in the 400 series to a recomended 550 depending on the water quality coming into the system. Cleaner water/lower tds and you can use the lower range of flow controls, very high tds use the 550...
