What does the pressure dew point of an air compressor mean?
In the term of air compressor, the pressure dew point is used to describe the moisture content in the air compressor. It refers to the current pressure. The temperature at which water vapour is converted to water. Low pressure dew point means that the amount of water vapor in compressed air is less.
When the moist air is compressed, the water vapor density increases and the temperature rises. When the compressed air cools, the relative humidity increases. When the temperature continues to drop to 100% relative humidity, water droplets are released from the compressed air. The temperature at this point is the pressure dew point of the compressed air".
