Description
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.
