External Flow Control - 900ml/min for 100 gpd

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-900-JG is simple to install - just push the 1/4" tube firmly into the quick connectors.

  • 1/4" QC x 1/4" QC
  • Quick and easy installation
  • RO Membrane Flow Rate: 100 GPD
  • Drain Flow Rate: 900 ml/min
  • Rinse Ratio: approximately 3.4:1 (drain:RO)
