The STAUFF Mini Water Vac purifies hydraulic system oil, eliminating water, gas and particulate matter. The device dehydrates and cleans most types of oils such as lubricating, hydraulic, transformer, and switch oils while it neither removes nor alters oil additives. The purified oil satisfies the most stringent quality requirements. The water removal process is based on pure vacuum evaporation inside a vacuum chamber at a maximum temperature of +65 °C / +149 °F. The oil temperature can be set using the integrated heater thermostat. The dehydration and filtering process is fully automatic and is controlled via the PLC.
