WM-Series Wall Mount Reverse Osmosis Systems

AMI Wall Mount Reverse Osmosis System

Designed to produce low dissolved solids water from tap or well water, WM-Series wall-mounted RO systems are compact and efficient, making them ideal for space-conscious installations.

These systems use high-efficiency reverse osmosis membranes to deliver reliable water purification. Common applications include carwash spot-free rinse, water stores, whole house systems, laboratories, ice makers, humidification, misting, and more.

Notes and Voltage/ Ordering Information

  • All dimensions and weights are approximate.
  • Capacity Basis: 24 hrs/day
  • Systems rated at: 77°F (25°C) using 1000 ppm sodium chloride solution operating at approx. 175 psi pressure.
  • Minimum feed pressure to RO System: 40 PSI. System capacity changes significantly with water temperature
  • Chlorine must be removed with a carbon filter prior to the RO system, if present in the feed water.
  • Pretreatment for water hardness using a softener or antiscalant injection should be added to avoid scaling the membranes.
  • Feed water turbidity: Less than 1 NTU; Feed water silt density index (SDI): 3 maximum. If exceeded, pretreatment with media filter recommended. All pretreatment equipment and SDI test kits are available from Applied Membranes.

Voltage: Above models indicate recommended voltage codes per model. Available voltages:
• 116 = 120V/1ph/60hz • 215 = 220V/1ph/50hz.
• 216 = 220 or 230V/ 1ph/ 60hz • Three phase not available.
