Desiccant is a dehumidifying agent used in compressed air dryers which attracts moisture from the atmosphere. It adsorbs and holds particles of water to itself. When desiccant becomes soiled or broken down over time, it becomes less effective. Inadequate desiccant can increase energy consumption via lower compression efficiency, air leakage, or pressure variability.
