The humidity of the ambient air is contained in the intake air, because of this the condensate always accumulates during compressing the compressed air in the compressor. The contamination containing dust and dirt particles or aerosols, are then located in the condensate in highly concentrated form . Again and again, the condensate accumulates in the additional compressed air treatment (filtration and drying) procedure. The condensate technology enables this polluted and environmentally harmful waste product to be discharged and treated, as it must not be initiated into the sewer system.
