Diameter: 170 mm
Height: 380 mm

The 2 port head (2PDR) has a single inlet and single outlet. The integral bypass allows approximately 30%* untreated water to pass through, to improve taste, colour and odour, and increase capacity.

  • The new system doesn't mix carbon with the resin, so regeneration becomes possible with positive results for the environment.
  • The carbon is located in the riser tube, which is the best place for polishing the water, giving maximum taste reduction.
  • The vessels use regenerated resin, which has a higher exchange capacity than new resin, so it will give maximum service time.
  • Fitted with 3/4" NRV male fitting on the inlet / outlet.
