A simple, robust, low maintenance oxygen cone for RAS with a capacity of 115 m3/h. An oxygen cone is used to saturate water with oxygen in closed circuits and recirculating aquaculture system - RAS in order to create aerobic conditions. Oxygen cones differ in several parameters, including the key ones: capacity and type (pressure and non-pressure). The main advantage of OG-115 oxygen cone made of 100% stainless steel is its robust construction. OG-115 oxygen cone is ideal for large-scale companies. Nowadays most of oxygen cones are made of polymer materials and plastic, which can not do with mechanical damages and pressure surges. Stainless steel oxygen cones are free from these disadvantages. When purchasing an oxygen cone, please, pay special attention to its overall and mounting dimensions, as pipelines for its feeding are usually projected and built prior to the oxygen cone installation.
