AIR DRYERS • Function: The function of air dryers is to remove all water vapour/moisture from the air leaving the compressor. • As we know, the atmospheric air contains moisture to a varying amount depending on the prevailing atmospheric conditions. Even after compression in the compressor, the air contains the same amount of moisture. This moisture should be removed before the air is fed into any pneumatic system components. Thus air dryers are placed at suitable points in the pressure air line to safeguard the pneumatic components from the corrosive effects of moisture. • The three main types of air dryers used to remove the moisture in the compressed air are: 1. Refrigerated dryer, 2. Deliquescent dryer, and 3. Absorption dryer. The construction and operation of a typical deliquescent-type dryer is illustrated in Fig.11.14. It uses a chemical agent called a dessicant. As shown in Fig.11.14, the moisture air enters at one end, passes through the chemical agent, and passes out at the other end. The chemical agent absorbs water vapour/moisture and slowly dissolves it as a liquid. The liquid is collected at the bottom of the unit where it can be drained.1. What are Air Dryers ?
