Small, compact, quiet and easy to install, the CAS 1 Combi-Separator combines air-water separation and amalgam separation. The two-stage system with a cyclone separator and dynamic separation turbine achieves a much higher separation capacity than conventional technology. The amalgam separator is on the same shaft as the air-water separator but not directly connected to it, thus saving the use of a spittoon valve. The ISO standards define the minimum European requirments for amalgam separators. In Germany this is regulated by the extensive construction and test principles of the German Institute for Structural Engineering (DIBT) Berlin. The amalgam centrifuge of the CAS 1 meets these conditions with its proven separation rate of almost 98%. Connecting an additional rinsing unit to the CAS 1 can also prevent deposits and coagulation of blood. Apart from extending the components' service life this also significantly improves the hygienic condition of the overall suction system.
