Compressed air treatment is a method that dehumidifies and cleans after it leaves the air compressor. This is done using an air dryer and an additional filter beyond the air filter found in a compressor. Air is always contaminated with solid particles such as dust, sand, soot, salt crystals and water as it leaves the compressor. An effective compressed air treatment system lowers the dew point of the air and takes out the elements that may harm equipment downstream of the compressor and dryer. Remember the higher the ambient temperature is, the higher the ability to hold moisture.
Water contamination can also lead to microbial contamination, corrosion, blocked or frozen valves, cylinders, air motors and tools and premature wear/failure of equipment. Water contamination of compressed air systems can reduce production efficiency and increase manufacturing costs.
Who uses air dryers?
Both refrigerated and desiccant dryers are needed in many industrial applications to produce/protect final products, as well as to protect much of the pneumatic equipment that is used in many industrial facilities. Food/beverage packaging and manufacturing companies use dryers to prevent their actuators and assembly machinery from rusting or collecting moisture in the lines that prevents clean compressed air from flowing. Dryers are also used in textiles to keep fabrics free of moisture and to aid in the texture of produced products. Many electronics manufacturers need high levels of dry air so that humidity will not transfer over to the production of computers, cell phones, televisions, etc. These same industries often use moisture separators, oil-water separators and aftercoolers to further aid in the drying process, as well as removal of contaminants from any compressed air flow. Dust, dirt or other small particles are present in compressed air until they are removed by using filters, separators and mist eliminators.
Air treatment is necessary in almost all compressed air applications. From food manufacturing, to brewing beer, to building electronics, having dry compressed air is a must to prevent product and equipment damage.

Air dryers are used downstream of an air compressor to rid the compressed air of any moisture or humidity before it reaches your application or final product. Using air dryers is imperative in many applications such as the food/beverage industry, electronics manufacturing and spray painting in the automotive industry.
Compressed air will always contain some level of moisture depending on the environment and ambient temperature surrounding the compressor. Using the air while it contains moisture can cause a number of issues for your tools, other equipment and ultimately your business.
