<\/span><\/div><\/div><\/div>The rotary vane technology allows a technically simple structure of vacuum pumps. A consistently high vacuum level in continuous use is guaranteed by the circulating oil lubrication, perfectly matched materials and the most modern and precise manufacturing techniques. The oil separator format guarantees clean and oil-free exhaust gases thanks to its sophisticated extraction system with integrated oil return. Compared to other technologies and device types, there is another advantage in the low start-up costs.<\/span><\/p>\n<\/div><\/div><\/div><\/div><\/div>The advantages at a glance<\/h3>\n\n- Slats with a very long service life<\/li>\n
