Flow Controls (aka Flow Restrictors) are required for all RO systems and must be properly sized to the membrane capacity, typically 3-4 parts brine (drain water) to 1 part permeate (product water). The FR-650-JG is simple to install - just push the 1/4" tube firmly into the quick connectors.
Specifications:

• 1/4" QC x 1/4" QC
  
• Quick and easy installation
  
• RO Membrane Flow Rate: 75 GPD
  
• Drain Flow Rate: 650 ml/min
  
• Rinse Ratio: approximately 3.2:1 (drain:RO)

NOTE: To optimize the efficiency and performance of the RO system, we recommend the installation of a Permeate Pump.
