How to Size Air Treatment

Posted by IR Compressed Air on 6/11/2014
There are different classes of air quality that are dependent upon the particle size, moisture, and oil content in the air. A chart of the different classes of air and an example on how to determine the ISO class can be seen below. When sizing air treatment equipment, consider the quality of air the customer desires. 

Air Quality Class
Particle Size (Micron)Pressure Dew Point (°F) Oil Content (PPM)
10.1-94°F0.01
21-40°F0.1
35-4°F1
415-38°F5
540-45°F25
660-50°F40

Example: 
• 1 Micron Particulate 
• 38° F Pressure Dew Point (moisture Content) 
• 0.1 PPM Oil Concentration 
The ISO Class for this air quality is “2-4-2” 

When selecting a dryer, size for the worst case to insure proper equipment performance under all conditions. The critical variables to consider when sizing air treatment equipment are: 
• Flow Rate (Max)
• Inlet Air Pressure (Min) 
• Inlet Air Temperature (Max)
• Ambient Air Temperature (Min and Max) 
• Process Water Temperature (Min and Max)
• Elevation (Max) 
• Location (Indoors vs. Outdoors)
