Orion Absorption Air Dryer has 2 bulbs containing silica gel or other absorbents with the principle of dehumidifying alternately, one bulb dehumidifies, the other regenerates. This type of air dryer has the disadvantage of compressed air loss from 10% to 20% (used to dry the desiccant in the regeneration process). Dew point temperature is achieved from -40 to -70℃ PDP. Therefore, the compressed air will be almost completely dry. Absorption dryers are used for factories that require high air quality such as food, pharmaceuticals, dairy, nanotechnology, etc.
