The Hydra-Max dechlorination system is a lightweight, easily transported device that provides reliable removal of chlorine from pressurized water flows. The system is constructed of 6061-T6 high strength, aircraft grade aluminum for maximum strength and durability with no electro-mechanical components. The Hydra-Max system is equipped with a 2½" NST coupling for fast and simple connection when flushing fire hydrants. A swivel elbow on the outlet allows operators to conveniently direct water flow exiting the unit, which may contain accumulated sediment or construction debris. By directing the flow, this unique feature provides the operator with safety assurance during each use. An engineered alternative to bulky and ineffective diffusers, the Hydra-Max system combines superior performance with portable convenience and operational ease.
