This NSF 42 Certified filtration system is designed for

  • supply pressures up to commercial ring main pressures of 125 psiG
  • high volume water usage locations
  • removing Chlorine from treated drinking water supplies
  • examples: food & beverage production, large schools, campgrounds, Marae's, Shopping Centres, small housing developments


  • NSF 42: Chlorine Reduction; 1,000,000 litres @ 113 Lpm


  • 4 x 20" Jumbo filter cartridges
  • Cartridges: Melt Blown then 3 x Carbon
  • All filter heads fitted with glycerine filled gauges to indicate 'plugging'
  • Performance: 1st sumps 1 micron meltblown protects the following Carbon cartridges granules from becoming coated with suspended solids (silt / mud). 2nd sumps carbon then removes a significant amount of the chlorine, with 3rd & 4th sumps carbon cartridges removing the 'remainder' of chlorine. Residual Chlorine at 1,000,000 liters still an amazingly low 0.5 mg/L, a reduction from the test loading of 2.0 mg/L. The NSF Pass concentration must be 1.0 mg/L or lower.
