FW-500 Cooler Reverse Osmosis Membrane

FW-500 Cooler Reverse Osmosis Membrane is a RO Membrane for FW-500 and 2500 series Bottless Water Coolers with a 4 stage RO system. With a guaranteed delivery of 100 gallons per day(gpd), this membrane is suitable for office locations where a high demand of clean drinking water is needed.The membrane works with floor model FW-500-RO and FW-2500RO filtered water coolers.

The RO membrane is the main filter in the Reverse Osmosis system that stops and rejects the majority of water contaminants. In order for the membrane to maintain its performance for city or municipally treated water, it is important to make sure that your carbon pre-filters are of good quality and are not too old otherwise, it may get damaged by chlorinated water.

Reverse Osmosis membranes produce very clean water, close to being distilled. You can test the quality of your RO water via a TDS meter, a device that measures Total Dissolved Solids. A new membrane should reject 95% to 98% of the dissolved solids and other contaminants. As it ages, it will let more and more contaminants through.
