50 gpd (gallon per day) Black Max TFC (thin film composite) Residential Reverse Osmosis Membrane by Waterite.

Fits all Waterite Vectapure and WR series Reverse Osmosis systems and most standard residential membrane housings.

If your system already used a 50 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 50 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 reaplce this vlave when replacing your membrane.

The matching flow control valve to this 50 gpd rated membrane is a 350ml flow restrictor part # FR350EZ
