FR-450-02 Flow Restrictor: Optimize Residential RO Systems for Consistent 400 ml/min Water Flow

If you’re looking to maintain precise water flow in your residential reverse osmosis (RO) system, the FR-450-02 Flow Restrictor delivers reliable performance and long-term efficiency. Designed specifically for water softener and filtration setups, this female 400 ml/min flow restrictor ensures optimal pressure balance and system protection. Its durable construction and compatibility with residential RO components make it an essential upgrade for smooth water treatment operations.

Key Benefits

• Maintains consistent 400 ml/min flow rate to enhance RO membrane efficiency
• Prevents system overpressure, protecting filters and membranes from damage
• Easy female connection design simplifies installation and replacement
• Compact and robust construction ensures long-lasting durability in residential setups
• Helps optimize water usage, reducing waste during filtration cycles
• Compatible with a wide range of residential RO components for seamless integration

How It Works

The FR-450-02 flow restrictor controls the water flow rate exiting the RO membrane, maintaining a steady 400 ml/min output. By restricting excessive flow, it balances the system’s pressure and prevents damage to delicate filtration components. This controlled flow also ensures that water has adequate contact time with the membrane, improving purification efficiency and extending membrane life.

Installed inline after the RO membrane, it regulates the reject water flow back to the drain, helping maintain the optimal pressure differential that is critical for effective reverse osmosis operation in residential water softener systems.

What to Expect

Once installed, you’ll immediately notice a steady and controlled water flow that supports consistent system performance. In the first days and weeks, the flow restrictor helps maintain stable pressure and flow rates, ensuring your RO system runs smoothly without fluctuations that could impair filtration.

Over time, the durable design reduces the need for frequent replacements, and regular system maintenance remains straightforward. Its reliable performance contributes to longer membrane life and fewer system interruptions, helping you enjoy clean, softened water with minimal hassle.

What’s Inside

• Polypropylene Housing – Provides chemical resistance and durability for continuous use in water softener systems
• Precision Orifice – Calibrated to maintain exact 400 ml/min flow rate for optimal RO membrane performance
• Female Threaded Connection – Ensures secure, leak-free attachment to standard RO tubing and components
• Internal Flow Channel – Designed to minimize turbulence and pressure loss within the system

How to Use

1. Turn off the water supply and depressurize the RO system before installation.
2. Locate the flow restrictor position downstream of the RO membrane, typically on the reject water line.
3. Remove the old flow restrictor, if applicable, by unscrewing the female connection.
4. Install the FR-450-02 by securely threading it onto the corresponding tubing or fitting; hand-tighten to avoid leaks.
5. Restore water supply and check for leaks or irregular flow; adjust connections as needed.
6. Monitor system performance during initial operation to ensure stable flow and pressure.
