How often should desiccant be changed?
once every three years
We recommend that a desiccant be replaced once every three years for open-cycle systems and once every two years for closed-cycle systems. A desiccant may degrade more quickly depending on the environment where it is used. Dew point temperatures offer a good indication for when to replace your desiccant.
How do desiccant dryers work?
How Does a Desiccant Dryer Work? The general working principle of desiccant air dryers is simple: moist air flows over hygroscopic material (desiccant) and is thereby dried. The exchange of water vapor from the moist compressed air into the desiccant causes the desiccant to gradually be saturated with adsorbed water.
When should I replace my air dryer desiccant?
For compressed air dryer applications that only require 0° dew point, a simple moisture indicator that changes in color can be used. Activated Alumina desiccant is typically good for three to five years before it needs to be replaced.
How do you size a desiccant air dryer?
To size the desiccant air dryer to match this compressor, we need to calculate 65% of the total CFM, in this case, 20. The max output is no more than 13 CFM or 65% of the total CFM of 20. The desiccant air dryer only needs to work at 13 CFM to fit the compressor and match the total dry air needed.

How does a desiccant work?
Desiccants are commonly used to keep products dry and stable. Dry desiccants can absorb moisture from air either by physical adsorption or by chemical reaction, and thus reduce the humidity in the headspace of sealed containers. The moisture in silica gel can be removed by drying at a temperature greater than 110°C.
