RO flow restrictor for Home RO System 420 ml

RO flow restrictor for Home RO System 420 ml for 50 GPD RO Membranes Model # PFR402Q-420 Flow restrictors in RO (Reverse Osmosis) systems control the flow rate of wastewater leaving the membrane.  Creates pressure: They slow down the flow of wastewater, which builds up pressure inside the RO membrane housing. Helps filtration: That pressure forces water through the RO membrane, improving filtration. Prevents waste: Without a flow restrictor, water would rush out too fast, reducing efficiency and wasting filtered water. So basically, they balance the system to ensure clean water gets properly filtered without wasting too much. Most common  flow restrictors to pair with your RO Membrane Example Sizes and Flow Rates: 300 mL - 36 Gallons Per Day 420 mL - 50 Gallons Per Day 550 mL - 75 Gallons Per Day 800 mL - 100 Gallons Per Day
