1.3 Basic
Compressed air contains contaminants such as water, oil and particles. Impurities need to be removed
or their concentration reduced to an acceptable level according to the requirements of the application.
The ISO 8573-1 standard specifies the purity / quality of the air for contaminants. The humidity (water
vapor content) can be expressed in terms of Pressure Dew Point (PDP). Dew point is the temperature
at which the air is 100% saturated with moisture. When the air temperature falls below the dew point,
moisture condenses. Reduction of moisture content to the point of dew point +3°C can be achieved by
refrigeration air dryers.
1.4. Refrigeration air dryers
Refrigeration air dryers are the best choice in all standard applications, where pressure dew point 3 °C
suffices. Examples of such applications are process air in the processing industry (pneumatic
equipment, wood industry, paint shop, chemical industry, pharmacy, etc.).
1.5 Proper use
