EVAC
EVAC vacuum collection systems include water-saving vacuum toilets, vacuum generation units and vacuum collection units. Vacuum generation units collect wastewater and condensate water by vacuum pumping it into a sewage treatment plant or collection tank. The latter are used to collect black water, which is waste from toilets and urinals, and gray water, which is waste from sources like washbasins, sinks, and showers. Vacuum collection units are also used in conjunction with freezer and refrigeration equipment to collect condensate water.
