Refrigerated Air Dryers Series IDF/IDU Standard/High Temperature Air Inlet Type Protect Pneumatic Equipment from Moisture! An air dryer removes the vapor from the moist compressed air delivered by the compressor, and prevents it from causing the pneumatic equipment to fail. Effects of moisture on equipment Malfunctioning of valves and actuators caused by dripping grease Decomposition of auto drain caused by rusting inside pipes Generation of water droplets Increased up to the Air flow capacity Power consumption Coefficient of destruction for ozone is zero. Note) Except IDF370B Improved corrosion resistance with the use of stainless steel, plate type heat exchanger
