Reverse Osmosis Flow Restrictors

Reverse osmosis flow restrictors are crucial components in an RO system, serving to regulate the flow of water through the membrane. This creates the backlog of pressure within the membrane housing to force the water through the membrane element.

Flow restrictors contribute to extending the lifespan of RO membranes by preventing excessive water flow, ultimately promoting consistent and reliable water quality over time.

To better control the water flow in your filter system, order high-quality flow restrictors with Finerfilters today. We offer fast, worldwide delivery for your convenience.
