Low dew-point temperature Pressrue dew-point 2-7 鈩?/p> Working principle The content of water vapor in compressed air is proportional to the temperature: when the pressure is constant, the higher the temperature, the higher the content of water vapor;The lower the temperature, the lower the water vapor content. So the drying effect is achieved by lowering the temperature of the compressed air and removing the condensed liquid water. In simple terms, it means "frozen dehumidification鈥?/p> PD series Performance parameterAir Dryer price website:http://www.dmgmachines.com/air-compressor/air-dryer/
