Kaeser's Eco-Drain was selected by Plant Engineerign readers as Product of the Year 2000, receiving a bronze medal in the compressed air category. Our coompressed air drains feature a reliable, calibration-free capacitance sensor that accurately measures condensate levels. Therefore, only contaminated condensate is discharged, but not valuable compressed air. The Kaeser Eco- Drain is ideally suited for use on dryers and filters. The robust aluminum housing and superior 3/2 valve technology ensure many years of reliable service even when subjected to harsh condensate.
