The atmosphere sucked by the compressor is known as a gas mixture that always contains water vapor. However, the ability of air to absorb water will vary. It mainly depends on the temperature. If the temperature increases, the ability to absorb water vapor will also increase.
Water will condense only when the compressed air has to be re-cooled as necessary. This condensate is then separated in a downstream cyclone or compressed air tank. However, after that, the compressed air was still 100% saturated with water vapor. With further cooling, a large amount of condensate will still be generated in the pipe network and at the point of use. Without additional compressed air drying, breakdowns, production interruptions, and expensive maintenance and repair work are inevitable.
