The Pentair GRO-50EN features an industry leading Thin Layer Composite (TLC) membrane. This membrane is encapsulated which maximizes the life cycle of the cartridge inside. The flow rate for this membrane is 50 gallons per day (GPD), and is based on nominal performance. Most standard membranes have a 3:1 ratio which means for every 3 gallons of waste water that goes down the drain, you get 1 gallon of RO water. That ratio is only a 25% recovery of good water. What separates this membrane from the competition is the GRO-50EN features 50% recovery which is a 1:1 ratio! That means for every 1 gallon of waste water down the drain you get 1 gallon of RO water. No other membrane in the industry can make that claim!
Specifications:

• Flow Rate: 50 GPD
• Max Pressure: 125 PSI (6.90 bar)
• Max Temperature: 120° F (49° C)
• pH Level: 4 - 11
• Free Chlorine: 0.1 PPM
• Ratio: 1:1

Kit includes:

• 50 GPD Encapsulated TLC membrane
• 1/4" Tubing

Recommendation:

The GRO-50EN does not include a flow control. To get the peek performance from your membrane our Water Experts feel it is critical that you also purchase the a flow control. In order to a obtain 1:1 ratio, we recommend using FRIL86-150-4Q.
Note: This can lead to premature membrane fouling and reduced membrane lifespan.
