Compressed air treatment, also referred to as air preparation, is the process of improving the quality of air that is supplied by the air compressor. Air compressors generate hot and humid pressurized air that may contain water, dirt, oil, and other contaminants. These products filter, cool, dry, and regulate the air to protect downstream components and equipment from damage and to improve performance. They are installed on the supply lines of compressed air systems in a wide variety of industrial applications that require a consistent supply of compressed air.
