Dialyzers are filter units used to wash the blood of people with chronic kidney disease. B. Braun Avitum Saxonia GmbH is one of the world's largest manufacturers of these medical products. Compressed air plays a special role in assembly: hardly any machine runs without it. In order to ensure high availability of this medium despite increasing demand for compressed air, the manufacturer has now supplemented the three existing water-injected screw compressors of the LENTO 46 series from ALMiG with a further unit of this series. Special features: energy-efficiently generated oil- and germ-free compressed air.
