What is the function of an air dryer?

• To remove excess moisture so as to bring air humidity and dew point to reasonable levels.

• To increase excess moisture so as to bring air humidity and dew point to reasonable levels.

• To remove excess moisture so as to bring air humidity and point to reasonable levels.

• To increase excess moisture so as to bring air humidity and point to reasonable levels.

In a bulk air system, what is usually required to remove excess moisture?

• Aftercooler only

• Aftercooler and separator unit

• Aftercooler, separator unit and air dryer.

What is dew point?

• Dew point is the temperature at which your compressed air is not fully saturated, causing air not to be able to hold any more water vapor, causing the vapor to condense.

• Dew point is the temperature at which your compressed air becomes fully saturated, where air can hold more water vapor, causing the vapor not to condense.

• Dew point is the temperature at which your compressed air becomes fully saturated, where air can’t hold any more water vapor, causing the vapor to condense.

• Dew point is the temperature at which your compressed air becomes fully unsaturated, where air can hold more water vapor, causing the vapor not to condense.
