Cuno Aqua-Pure DF290-CL Dual Port Water Filtration System 56236-01

The Aqua-PureŽ DF290-CL Dual-Flow water filtration systems assure consistent
high-quality water for the multiple applications of cold beverages and ice at a
combined flow rate of up to 7.66 gpm (29.1 lpm). Two separate streams exit the
manifold. The first stream (STREAM ONE) supplies cold beverage applications. The
second stream (STREAM TWO) supplies the ice machine.

  • STREAM ONE combines cyst, bacteria, chloramine, chlorine taste and odor, and
    sediment reduction for a total volume up to 30,000 gallons (113,563 liters) at a
    flow rate up to 2.66 gpm (10.2 lpm).
  • STREAM TWO reduces cyst, bacteria, and sediment. The flow rate is up to 5 gpm
    (18.9 lpm), and the life is 30,000 gallons (113,563 liters). Chloramine and/or
    Chlorine are not removed from this stream to preserve their disinfectant
    properties. A scale-inhibition medium


  • 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

    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).

  • 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.
