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-450-JG is simple to install - just push the 1/4" tube firmly into the quick connectors.

Additional Specifications:
  • 1/4" QC x 1/4" QC
  • Quick and easy installation
  • RO Membrane Flow Rate: 50 GPD
  • Drain Flow Rate: 450 ml/min
  • Rinse Ratio: approximately 3:1 (drain:RO)
NOTE: To optimize the efficiency and performance of the RO system, we recommend the installation of a Permeate Pump.
