Do you have water in your compressed air system?

This situation is almost everywhere, but it can have serious consequences for your compressed air system and the quality of your final product. Causes of water in compressed air systems When air is compressed, condensation occurs. 

The following factors determine the amount of water: 

Inlet conditions 

Ambient air quality 


Warm, humid air has a higher moisture content, which means more water is removed from the compressor. The higher the pressure of the compressed air, the less water there is and the easier it is to dry. Think of a water-soaked sponge; the more you squeeze it, the less water it contains.

Why should I add an air dryer to my compressed air system?

Many tools and equipment powered by compressed air are not water or moisture resistant. Many processes that use compressed air are processing products that are not water or moisture resistant. Free water inherent in the compressed cycle often forms in the compressed air circuit.

Untreated compressed air contains solid, liquid and gaseous contaminants that pose a significant risk because it can damage your air system and the final product. Moisture is one of the main components of untreated air and can cause problems such as 

Water in compressed air systems usually causes corrosion, which can lead to rust in the compressed air system. These rust particles will be released and transported through the compressed air system. Corrosion in air or pneumatic instruments gives incorrect measurements, resulting in interruption or shutdown of the system process. 

The cause of wear inside the compressed air lines, leading to holes and thus air leakage, leading to pressure drop. Means loss of effort and money. 

This can lead to damage or failure of compressed air tools and can result in contamination of the processed product. Free water or moisture in the compressed air system can sustain the growth of bacteria, or moisture can be absorbed by the processed product, leading to quality deviations and product spoilage. For example, it may adversely affect the color, adhesion and surface finish of paints applied with compressed air. This can lead to rejection of your product and affect your profitability. 

In cold weather, water can freeze in the control lines, which can cause the controls to malfunction.

How does an air dryer work?

Air dryers remove moisture from the air.

Each drying system - adsorption dryers, freeze dryers and membrane dryers - uses its own technology.

The measured value of the dried compressed air after treatment is called the "dew point". The lower the dew point temperature, the lower the water vapor content of the air. The dew point is the actual temperature at which condensation begins. For example, if the dew point is -40 C°, this means that condensation will only start when the compressed air temperature drops to -40 C°.
