The Kaeser Eco-Drain Model 31 automatically removes condensate from aftercoolers, filters, dryers, tanks and air lines. Special sensor technology enables the unit to open only when liquid is present, thereby conserving valuable compressed air. Long-life construction and superior diaphragm valve technology ensure worry-free operation and many years of highly reliable service. (For receiver tank applications, we recommend a more aggressive maintenance schedule.)
