Reverse osmosis flow restrictor for RO systems with 25 or 50 GPD membranes. Made in U.S.A, built-in 1/4″ quick connect fittings, easy to install.
A reverse osmosis flow restrictors is required for all reverse osmosis systems. A reverse osmosis flow restrictor creates back pressure on the membrane to maintain a desired ratio of reject flow (to drain) and permeate (product) flow. Put simply, an RO flow restrictor determines the amount of water that flows to drain. We carry reverse osmosis flow restrictors for 25 and 50 gallons per day (GPD) membranes.
Every reverse osmosis unit has a device called a flow restrictor (also known as a flow control or capillary). A reverse osmosis flow restrictor determines the amount of water that flows to drain. It does so by creating pressure on the membrane in order to achieve a desired ratio of water to drain and product water.
It is recommended that you replace the reverse osmosis flow restrictor each time you replace your reverse osmosis membrane to keep your system operating at peak efficiency.
A reverse osmosis flow restrictor should be sized to fit the membrane’s production rate (gallons per day). Because flow restrictors create back pressure on the membrane, having an incorrect flow restrictor will damage your membrane and/or reduce the product water flow. Flow restrictors are rated by a flow rate expressed as milliliters per minute (ml/min).
An in-line reverse osmosis flow restrictor is easy to install. The RO flow restrictor is inserted into the 1/4″ drain line tubing: push your 1/4″ tubing firmly into the quick connect fittings located on both the inlet and outlet ends of the RO flow restrictor.
