The US Water Systems AR-3 light commercial reverse osmosis system is engineered for applications requiring smaller amounts of RO-quality water with an eye of efficiency of operation.


  • Strong powder-coated steel bracket - Will not rust
  • Ultra low energy RO membrane - Operates at 80 psi to extend life and cut energy costs
  • Robust 1/3 HP Motor and Fluid-O-Tech Pump - Time-proven & low lead
  • 20" Pre-Filter Housing - 5 Micron filter protects the membrane to extend life
  • Flow Meters - Enable monitoring of Concentrate, Permeate, Recycle
  • Pressure Gauges - To totally monitor system functions
  • Stainless Steel Needle Valves - Precise adjustment with zero corrosion
  • Built in Dual TDS Meter - Allows system performance to be constantly available
  • Low-Pressure Shut Off - Protects the pump from running dry
  • Built in the USA - This is not some cheap model from the Far East or Mexico
  • Two-Year Warranty - When used with proper pre-treatment

Test Parameters: *550 TDS Filtered (5 Micron), De-Chlorinated, Municipal Feed Water, 65 psi (4.50 bar) Feed Pressure, 100 psi (6.89 bar) Operating Pressure, 77 Degrees F (25 Degrees C), Recovery as stated, 7.0 pH. Data taken after 60 minutes of operation. Scale prevention measures must be taken to prolong membrane life.

Low temperatures and high feed water TDS levels will significantly affect system's production capabilities. Computer projections should be run for individual applications which do not meet or exceed minimum and maximum operating limits.

NOTE: US Water rates their reverse osmosis systems under industry standards which are tested at 77 degree F, 500 TDS and 60 psi pressure. Production can vary dramatically depending upon water pressure, temperature and TDS (total dissolved solids) levels. US Water does not make these standards - we just adhere to the industry standards when testing and report what the standards require. Every manufacturer uses these standards.
