Compressed Air Dryer Installation
The purpose of a compressed air dryer is to remove water vapor from compressed air. This, in turn, lowers the temperature to which the air can be cooled before water vapor condenses into liquid water and protects pneumatic components from corrosion.

Temperature
-
Some compressed air dryer condensers are cooled by air, others by water. Air-cooled dryers should be installed in well-ventilated areas with a maximum ambient temperature of 100-120 degrees Fahrenheit, so they can exchange heat with their surroundings. Water-cooled dryers can be installed in areas with higher ambient temperatures.
Refrigerated Dryers
-
Refrigerated compressed air dryers should not be installed where compressed air lines run outdoors in freezing temperatures. Similarly, although they are more effective at high air pressures, they should not be installed for applications where the pressure rating of the dryer is likely to be exceeded.
-
Filtering
-
Compressed air dryers remove water vapor, but not liquid water. In order to be effective, they should be installed with a general purpose filter, to remove liquid water and solids, upstream of the dryer itself.
