  • TW30-1812-50HR replaces TW30-1812-50 which has been disonctinued by the manufacturer.  TW30-1812-50HR offers higher rejection (99%)  than the retired TW30-1812-150 (98%).
  • BW60-1812-75 replaces TW30-1812-75, offering higher rejection as well as longer life in high hardness applications.
  • TW30-1812-100HR replaces TW30-1812-100 which has been disonctinued by the manufacturer.  TW30-1812-100HR offers higher rejection (98% min)  than the retired TW30-1812-100.
  • TW30-3012-500 uses 3″x12″ membrane housing (part number PV3012C) and does not fit standard residential housings.
  • Permeate flow and salt rejection based on the following test conditions: 250 ppm softened tap water, 77°F (25°C), 15% recovery and the specified applied pressure.
  • Minimum salt rejection is 96.0% (BW60-1812-75 minimum is 97.0%)
  • Permeate flows for individual elements may vary +/-20%.
  • Product specifications may vary slightly as improvements are implemented.
  • For ease of installation, element O-rings have been pre-lubricated with glycerin.
