Flow rate 3.6 m³/h / final vacuum 4 mbar abs. - The integrated KNF self-drying system ensures that condensate is quickly removed from the pump heads without the vacuum changing. This significantly shortens the process time and protects the pump heads. - Chemical-resistant and therefore also suitable for use with very aggressive/corrosive gases and vapors Technical data Application rotary evaporation, distillation, vacuum oven, vacuum concentrator Flow rate (m³/h) at atm. Pressure 3.6 Ultimate vacuum (mbar abs.) 4 Operating pressure (bar) 1 Hose connections (mm) ID12 Permissible media and ambient temperature +5 ... +40 °C Weight (kg) 14.8 Dimensions W x H x D (mm) 291 x 278 x 331 Material Pump head PTFE Membrane PTFE-coated Valves FFPMMeer tonenMinder tonen
