      The basic theoretical knowledge of air that everyone who uses an air compressor should understand

      1 What is air? What is normal air?    Answer: The atmosphere around the earth, we are accustomed to call it air.   The air under the specified pressure of 0.1MPa, temperature of 20°C and relative humidity of 36% is normal air. Normal air is different from standard air in temperature and contains moisture. When there is moisture in the air, once the moisture is separated, the air volume will be reduced.
