The Modular Sand Media Filter is an advanced filtration system, designed from the ground up, especially for media filtration, to provide the ultimate Sand Media Filter. Each Modular Filter Tank is capable of flowing between 15 and 25 gallons per minute depending on the mesh of the sand, coarse or fine sand media. Each Modular Sand Media Filter Tank is self contained with a flush valve. The flush valve can be operated manually or automatically. Automatic Flushing is operated by a Two Wire Back Flush Controller (96 station tanks), thereby keeping the number of wires leaving the controller to the entire Modular Filter System to only two wires. Each Modular Sand Media Filter tank is equipped with a Receiver and Solenoid.
