Unnecessary water in compressed air, either in liquid or in vapor, can cause different operational problems for user of compressed air. Our air dryer and air filter is designed to solve this problem. It could be used for a wide range of industrial and commercial applications. During the process of air compression, atmospheric contaminants, including water vapor, are concentrated. This raises the dew point of the compressed air and cause condensation within the pipes as the compressed air cools downstream of the compressor.
