Air dryers are used to lower the dew point temperature of compressed air, further reducing the amount of water vapor remaining in the process airflow. If applied correctly, a compressed air dryer should eliminate the possibility of liquid water forming in any downstream piping. Refrigerated air dryers lower dew point by reducing the actual air temperature to near freezing conditions, causing moisture to condense from the air. Once the water is removed via centrifugal action, the air is reheated to a usable temperature. Desiccant air dryers use the chemical adsorption method of drying and can typically achieve dewpoints as low as -100oF. Coalescing filters collect and extract liquid water and oil. Particulate filters trap unwanted solid contaminants. Adsorbing filters soften odors and polish compressed air. For more details information, please visit http://www.airtek.com
