• Filter/Membrane Performance Specifications:
  • Carbon Pre-Filter:
    • Length: 43.2 cm (17.0")
    • Diameter: 7.4 cm (2.9")
    • Flow Rate: 14.2 LPM (3.75 GPM)
    • Average Life: 6-12 months, 37,850 liters (10,000 gal)
  • RO Element:
    • Length: 47.6 cm (18.75")
    • Diameter: 8.0 cm (3.16")
    • Flow Rate: 0.95 LPM (0.25 GPM)
    • Average Life: 2-4 years
  • Carbon Post-Filter:
    • Length: 25.4 cm (10.0")
    • Diameter: 5.1 cm (2.0")
    • Flow Rate: 2.8 LPM (0.75 GPM)
    • Average Life: 6-12 months
• Average Daily Production Rate: Hundreds of liters (compared to 37,9-189 LPD (10-50 GPD) for standard RO systems).
• System Efficiency/Recovery: 22.7% (compared to as little as 5% for standard RO). This efficiency rating is identical to the recovery rating when the system is tested without a storage tank or when a storage tank is bypassed.
• Flow Adjustment Based on TDS: Estimated Flow Change from 750 ppm NaCl/RO = -0.0002 (TDS) + 0.15.
• Outline Dimensions: The PDF provides outline dimensions in inches (mm) visually. See the official PDF for exact tabulated values.
• Performance - Flow Rate Characteristics: Graphs illustrating flow rate characteristics at 50°F, 65°F, and 80°F based on 750 ppm TDS inlet water and driving pressure (psi) are available in the PDF.
