  1. Individual UF modules can be configured in parallel to provide increased system capacities.
  2. The individual UF module flow ranges depend upon the source water quality and pretreatment. Consult with AMI for specific design flow rates for a specific application.
  3. To avoid mechanical damage, do not subject the membrane to sudden temperature changes (>1°C/min) or water hammer
Fit in a standard filter housing with use of adapters. See “Parts” tab for more information.
