The conveying or processing of hazardous, toxic or particularly valuable substances requires an extremely leak-tight ventilation system. The very high leak-tightness, especially with gases, is only possible with the perfect interaction of several components, such as the shaft and housing seal. Precision – high-quality material – top engineering are the key words here.
