The air dryer is a system or piece of equipment that is used to remove moisture present in the air, particularly compressed air. Compressing air packs higher quantities of moisture in a small volume. It is used to suppress the dew point of your compressed air by removing water from it. Compressed air can contain moisture, which, under the right conditions, can reach the dew point temperature and condense into a harmful liquid. The dryer consists of a cylindrical vessel filled with a bundle of hollow, membrane tubes. The air dryer is made for use in the various industries and commercial uses.
