Hawks Hydro Vessels come in three models: 60, 80 and 135 litres per minute at 180 bar. The units are enclosed within a robust, hot-dipped galvanised steel shell which provides protection for the system and safety for the operators. They are designed to be compact and are shaped for ease of maneuverability over rough terrain as a key consideration. The power-packs can be dragged to where they will be used.
