They are very efficient oil separators having aeration units and with the relevant accessory filters and magnetic separators. Unwanted free oil is very efficiently removed from media such as coolants in machine tools, washing liquids, etc. At the same time the medium is aerated which counteracts anaerobic bacteria growth. The production range includes separators with a flow rate of approx. 70 l/h in stationary as well as in mobile execution up to units with flow rates of 5'000 l/h. All units are suitable for ambient temperature and in reinforced execution for hot applications (max. 80 °C) A range of different suction floats, all with automatic level adjustment, complement the coolant cleaners.
