Flow Restrictors Inline for RO

Hydronix Flow Restrictors
Hydronix IFR Series Flow Restrictors for Reverse Osmosis
Hydronix IFR-Series flow restrictors are designed to control the wastewater ratio in reverse osmosis (RO) systems. They ensure the RO membrane is properly rinsed by maintaining a specific flow rate to the drain, which is critical for membrane longevity and system efficiency.
The IFR series typically features 1/4" quick-connect fittings for tool-free installation. Choosing the correct model depends on your RO membrane's production capacity, measured in Gallons Per Day (GPD).
Selection & Installation Tips:
  • Matching: Always match the restrictor's flow rate to your membrane's GPD rating to maintain a proper "brine-to-product" ratio (typically around 3:1 or 4:1).
  • Maintenance: Flow restrictors can clog over time due to mineral buildup. It is widely recommended to replace the restrictor every time you replace your RO membrane to prevent premature membrane failure.
  • Orientation: These are inline components; ensure they are installed in the correct flow direction on the waste/drain line.
