FR-300-02, Flow Restr, Female 300 ml/Min, PFR-402Q1-300

Optimize Your Residential RO System with the FR-300-02 Flow Restrictor for Consistent Water Flow

The FR-300-02 Flow Restrictor is designed to precisely control water flow rates in residential reverse osmosis (RO) systems, ensuring optimal filtration performance. Unlike generic flow restrictors, this female 300 ml/min unit from Water Softener Plus offers reliable, stable flow regulation that protects your RO membrane and improves overall system efficiency. Built specifically for residential RO components, it addresses common issues like fluctuating pressure and inefficient water use.

Key Benefits

• Maintains consistent flow rate to maximize RO membrane lifespan and filtration quality
• Prevents overpressure that can damage system components or reduce efficiency
• Easy female threaded connection simplifies installation and replacement
• Compact design fits seamlessly within most residential RO setups without adding bulk
• Durable materials resist corrosion and wear, ensuring long-term reliability
• Helps conserve water by controlling output precisely, reducing waste

How It Works

The FR-300-02 flow restrictor regulates the volume of water passing through the reverse osmosis system by limiting flow to 300 ml per minute. Installed on the drain side of the RO membrane, it creates back pressure that forces water through the membrane at the correct rate. This controlled flow ensures efficient separation of contaminants while preventing excessive water waste.

By stabilizing flow, this component helps maintain optimal pressure balance within the residential RO system, safeguarding the membrane and other components from stress caused by irregular water movement.

What to Expect

Once installed, you will notice your RO system operating with steady water flow and improved efficiency within minutes. The immediate effect is a reduction in water waste and more consistent purified water output. Over the first days and weeks, the flow restrictor will help your system maintain stable performance, reducing the need for frequent adjustments or membrane replacements.

Long-term, the FR-300-02 requires minimal maintenance, as its durable construction resists clogging and wear. Periodic checks during routine system service will ensure it continues to regulate flow effectively, contributing to the longevity and reliability of your water treatment setup.

What’s Inside

• Precision Orifice Valve – Controls flow rate accurately to 300 ml/min, ensuring system balance
• Female Threaded Housing – Provides secure, leak-resistant connection compatible with standard residential RO tubing
• Corrosion-Resistant Polymer Body – Enhances durability against water exposure and system chemicals
• Compact Design – Minimizes space requirements within the RO system assembly

How to Use

1. Turn off the water supply to your RO system before installation.
2. Locate the drain line where the flow restrictor will be installed—typically between the RO membrane and drain tubing.
3. Unscrew the existing flow restrictor if replacing, or cut the tubing at the appropriate location for new installation.
4. Attach the FR-300-02 flow restrictor using its female threaded connection, ensuring a snug fit to prevent leaks.
5. Reconnect the tubing securely to the flow restrictor’s outlet.
6. Turn the water supply back on and check for leaks or irregular flow.
7. Monitor system operation for a few minutes to confirm steady water flow and performance.
