Miniature Desiccant Air Dryers

MDH-SERIES

Ultra-small desiccant compressed air dryers can be used for low-flow applications or with fractional horsepower air compressors. These units are heatless regenerative desiccant air dryers designed to produce low dew points. Extremely small footprint allows for packaging inside equipment cabinets or at point-of-use.
