• Ideal for Reverse Osmosis guard and post filtration.
• Complimentary to UV systems.
• High levels of Chlorine and organics removal.
• Lead and other heavy metal reduction.
• At the heart of every Doulton and British Berkefeld ceramic filter is the Sterasyl silver impregnated ceramic microfilter.
• The incorporation of silver locked within the ceramic structure inhibits the growth of bacteria giving the ceramics self-sterilizing properties and removes the need for boiling of the filter to remove or kill the impurities within the ceramic pores.
• The Doulton range of ceramic filter elements starts with the Sterasyl and with added core medias can become a three stage filter in one eliminating the need for expensive 4 and 5 stage systems.
• Doulton ceramics do not remove the beneficial minerals from the water ensuring the filtered water is enjoyable to drink and yet safe from harmful impurities.
• Doulton ceramic filters are manufactured to a diameter of 2 inchs/50mm with a 1/4 inch BSP threaded mount.
• They have the highly consistent and controlled pore structure necessary to remove a wide range of water borne contaminants over the life of the filter.
• All genuine Doulton ceramic filters are manufactured in accordance with ISO 9001:2000 quality assurance procedures which ensures highly consistant product quality with full batch traceability in operation.
• The Doulton Ultracarb is a three stage cartridge combining the highly efficient filtration properties of ceramic with the enhanced water treatment properties of activated carbon and the heavy metal reduction capabilities of ion exchange media.
• Three filtration stages within a single cartridge.
• The first stage consists of Doulton Sterasyl ceramic which provides genuine sub micron filtration.
• The cartridge reduces fine particulate matter bacteria cysts and turbidity.
• The incorporation of silver locked within the ceramic structure gives enhanced bacteriostatic and self sterilising properties.
• Second Stage: An inner core of activated carbon block removes chlorine and organic compounds.
• Third Stage: Ion exchange resin reduces Lead and other heavy metals.
• Chlorine Reduction: Volume capacity at >97%: 8000 liters (2000 gallons).
• Lead Reduction: Volume capacity at >98% removal efficiency: 8000 liters (2000 gallons).
• Working temperature range: 5-38 degrees C; Working pH range: 5.5-9.5; Minimum/Maximum working pressure: 125 psi.
