The Suttner ST4000 steam gun has been designed to be used in applications with a medium temperature of up to 200°C, and a max pressure of 20 bar. The especially designed valve housing allows the ST4000 to be used at extremely high flow rates. As well as being resistant to high temperatures, the sealing copolymer is suitable for all liquids based on mineral oil, as well as organic acids, alkaline solutions and seawater. The front entry hose connection allows for minimum heat radiation to penetrate the handle and trigger, and therefore the operator.
