Clean, drip-free, and odorless: Roediger's vacuum units reliably extract wastewater without forming aerosol clouds. Thus, the highest hygiene requirements are successfully met in sensitive environments such as hospitals and in confined spaces, e.g., on ships. Toilets, showers, and washbasins can be easily connected to the system. But the extraction pistols for emptying the wastewater tanks of train operators have also proven their worth and enable efficient and fast disposal.
