OWS33-RO Reverse Osmosis Office Water System

The OWS33-RO Reverse Osmosis System was designed to provide exceptional tasting water to any water cooler.

The OWS33-RO system reduces nitrates, heavy metals, total dissolved solids, cysts, sediment, chlorine taste
and odor, calcium and magnesium, and more.

The 33 gallon per day* high flux membrane provides higher water output to accommodate small to mid-size
office environments.

The TFC (Thin Film Composite) membrane allows for higher rejection rates than other style membranes, ensur­ing superior water quality.

The combination sediment/carbon prefilter extends the life of the RO membrane while the post filter polishes,
leaving the water idea for consuming.

Optional 2.5 gallon blader tank is available.

For both chlorinated and non-chlorinated water.
