  • Removes chloramines with the optional Catalytic Carbon upgrade
  • Much longer life and higher flow rates than carbon filter cartridges.
  • Carbon media lasts for 4 to 6 years or longer depending on water chemistry and usages.
  • Unlike carbon cartridges which can trap sediment and dirt, these systems automatically backwash out trapped sediment, alleviating pressure drop.
  • Carbon media easy and inexpensive to change out.
  • High-tech Ceramic Disc Valve: the moving parts of the 7500 series control valve feature super hard ceramic and graphite meshing surfaces for exacting tolerances, eliminating the need for O-rings or gaskets.
  • Easily programmable, multiple sequence set-up features, regeneration modes and interlocking capabilities.
  • Backwashes automatically based on time (days of the week) .
  • More efficient backwashes that use less water and require backwashing less frequently
  • Corrosion Proof: Resistant to sand, caustics, and acids.
  • Automatic recall after power outage and maximum day regeneration functions
  • Resists Abrasion: Patented ceramic discs are corrosion and abrasion resistant for superior durability and longevity.
  • Exceptional High Flow Rate with noticeable noise reduction during regeneration.


  • 7500-Rev2.5 Ceramic Disc Control valve with 110V - 230V 50/60 Hz. power supply.  Uses less than 20 watts of power.
  • certified filter tank
  • 1" NPT Pipe size: 1" in - out - drain fittings, easy to adapt to 3/4" pipe if needed.
  • Filter Media ( certified high grade activated carbon, filter gravel)
  • Bypass valve with 1" pipe connectors (can be adapted to 3/4" pipe size)

Advanced Features:

  • Very long lasting. Ceramic disc valve lasts years longer than standard piston type control valves and backwash over 150,000 cycles.
  • certified, one piece, seamless poly filter tank for long life
  • All activated carbon filter backwash systems include filter media, filter gravel, tank, & backwash control valve
  • High activity granular activated carbon is manufactured by steam activation from select coconut shell charcoal.
  • Removes low molecular weight organic compounds and their chlorinated by-products such as chloroform and other trihalomethanes (THM's).
  • Removes chloramines with the optional Catalytic Carbon upgrade
  • Iodine Rating: minimum 1000 mg/g

For Larger Sizes 1.5 Cf And Up: Higher Flow Rates Are Possible If Contact Time Is Not An Issue.  

For Example, To Remove Chlorine Tastes And Odors On City Water, 5 To 8 Gallons Per Minute Per Cubic Foot Of Carbon Works Fine Depending On Chlorine Levels. 

However, If You Are Trying To Remove A Particular Chemical Such As PFOS Or Benzene, Lower Flow Rates With Longer Contact Time Are Recommended.  Add KDF Cubes To Extend Life Of Carbon And Achieve Higher Flow Rates
