legacy Toray membranes are kept in stock specifically for older industrial systems that require exact matching of original flow specifications. While modern “D-Series” membranes are more efficient, these “Obsolete” models are often necessary for systems with fixed-speed pumps or specific pressure-drop requirements that cannot easily be re-calibrated.

Uses & Applications:

  • Legacy System Repairs: Direct replacement for systems built between 2010–2020.

  • Specific Pump Matching: For systems where modern high-flux membranes might cause pump cavitation.

Benefits:

  • Proven Compatibility: Eliminates the need for system re-engineering.

  • 28-mil Feed Spacer: Features the original wider feed spacer for better handling of high-turbidity water.

Size & Dimensions:

  • Capacity: ~8,000–10,000 GPD

  • Length: 1016 mm (40″)

  • Diameter: 201 mm (8″)

  • Weight: ~15.00 kg

  • Housing: Requires 8040 Industrial Pressure Vessel.
