Cuno Aqua-Pure DP290 Dual Port Water Filtration System 56242-01

Aqua-PureŽ Model DP290 DUAL-PORT water filtration system assures consistent
high-quality water for the multiple applications of cold beverages, ice, and coffee
at a combined flow rate to 10 gpm (37.8 lpm). Two separate streams exit the
manifold. Both streams have reduced sediment and chlorine taste and odor. One
stream has scale-inhibition media added from a dedicated cartridge to reduce the
ability of calcium and magnesium to precipitate as hard scale on the evaporator
plates of an ice machine and/or the heating coils of a coffee brewer. The other
stream supplies cold beverage dispensers and includes no added scale inhibitor.

  • DP290 combines chlorine taste and odor reduction with cyst, bacteria and
    sediment reduction, and provides protection from the harmful effects of scale
    for total volumes up to 108,000 gallons (408,823 liters).


  • One system with dual outlet connections simultaneously supplies cold beverage
    dispensers and ice machines/coffee brewers.
  • Up to 10 gpm (37.8 lpm) total flow of water especially treated for consistent
    great-tasting cold beverages, clear and consistent ice, and the perfect cup of
    coffee or tea.
  • Revolutionary IMPACTechnologyT dual-zone media cartridge construction
    combines a membrane in series with premium activated carbon to provide
    unsurpassed throughput and cartridge life.
  • Cartridge Life Warranted*.
  • Certified by NSF to Standard 53 for cyst reduction.
  • NSF Standard 42 and/or FDA CFR-21 compliance provides assurance of safety.
  • The removal of water-borne heterotrophic bacteria by membrane filtration
    as tested by CUNO.
  • Reduced scale build-up on evaporator plates and heating coil from the
    carefully-controlled (forced-orifice) addition of scale inhibitor as tested by CUNO.
  • SQCT - Sanitary Quick Change - encapsulated cartridge design allows for
    fast and easy change-outs with a 1/4 turn while minimizing the possibility
    of leakage and contamination.
  • 3/4" FNPT horizontal inlet and outlet ports allow direct or easily adaptable
    connections to existing plumbing lines.
  • Auxillary inlet gauge port allows optional monitoring of differential water pressure.
  • Exhausted cartridges may be incinerated for environmentally conscious disposal.


  • System includes a single-cartridge manifold with built-in pressure gauge,
    inlet water shutoff valve, outlet check valve, mounting brackets, a single
    cartridge filter, and a dedicated external scale inhibitor cartridge.
  • Auxillary inlet gauge port allows optional monitoring of differential
    water pressure.
  • Inlet and outlet plumbing connections are 3/4" FNPT.
  • Filter cartridge is double o-ring seal type.
  • System maximum operating pressure of 125 psi (862 kPa)
    and operating temperature of 100°F (38°C).
  • Recommended total service flow rate is up to 5.0 gpm (18.9 lpm).
  • Large filter cartridge incorporates carbon block media protected by
    a pleated pre-filter membrane. Second cartridge includes scale-inhibitor
  • System is NSF Standard 42 and/or CFR-21 compliant.
  • Large cartridge body is constructed from high-impact glass-filled
  • Cartridges are sanitary in design, requiring no contact with the
    filter media during cartridge change-out.
  • Filter cartridges require no pre-activation.

Do not use with water that is microbiologically unsafe or of unknown
quality without adequate disinfection before or after the system.
Systems certified for cyst reduction may be used on disinfected water that
may contain filterable cysts. EPA Establishment Number 070595-CT-001.
CUNO Incorporated recommends regularly scheduled maintenance and
replacement of the filter cartridge(s) in order for the product to perform
