RO Flow Restrictor 300ml – 1500ml

Flow Restrictors are required for all reverse osmosis systems. The flow restrictor must be properly sized to the RO membrane capacity. Flow restrictors create pressure throughout the reverse osmosis membrane element and maintain a desired ratio of reject flow (waste water) and product (RO) flow.

It is recommended that you replace the flow restrictor each time you replace your reverse osmosis membrane to keep your system operating at peak efficiency. The number on the flow restrictor indicates the flow rate, in millilitres per minute. The flow restrictor should match your reverse osmosis membrane’s production rate.
