  • Geo Ozone Manifold

    Geo Ozone Manifold

    Geo Ozone Manifold

    We have designed this manifold to connect the OZ618 or OZ818 to our UMC410OZ.  All connections picture are ozone resistant.  This manifold allows you to isolate the reactor for cleaning so you may change out carbon from the UMC periodically.  It also allows you to create some back pressure in the ozone reactor to maintain a 3 psi in the chamber and drain the units for maintenance.

  • GEO Reactor NR612, Nitrate reactor

    GEO Reactor NR612, Nitrate reactor

    GEO Reactor NR612, Nitrate reactor

    • Nitrate reactors and calcium reactor share much of the same build, the main differences being the construction of the manifold and lid along with filter pads to separate the media.
    • Any size calcium reactor listed can be fabricated to use the LSM sulfur media and the prices are the same as the comparable calcium reactor.
    • Reactors are sized according to chamber size; the first number being the diameter of the tube and the the second set of numbers being the height.
    • Pictured is our NR612 nitrate reactor. The chamber is 6″ in diameter and 12″ tall, the pump used for this model is the Sicce Syncra 1.5
    • The NR612 are in stock. Other sizes are custom orders and may take up to 2 weeks to ship.
