Construction Principle (Air/Refrigerant Circuit) IDFA22E, IDFA37E, IDFA55E, IDFA75E Humid, hot air coming into the air dryer will be cooled down by a cooler re-heater (heat exchanger). Water condensed at this time will be removed from the air by auto drain and drained out automatically. Air separated from the water will be heated by a cooler re-heater (heat exchanger) to obtain the dried air, which goes through to the outlet side. Auto drain Body Replacement Parts Model Auto drain replacement part no. Note 8) AD48 IDFA22E IDFA37E IDFA55E IDFA75E Note 8) The part number for the auto drain components without including the body part. Body part replacement is impossible. Refrigerated air dryer Auto drain Symbol Note 1) Air flow capacity under the standard condition (ANR) [atmospheric pressure at 20°C, relative humidity at 65%] Note 2) Air flow capacity converted by the compressor intake condition [atmospheric pressure at 32°C, relative humidity at 75%]. Note 3) The operation range does not guarantee the use with normal air flow capacity. Note 4) When operating conditions are different from the rated specifications, please select a model in accordance with the Model Selection (Page 71). Note 5) Product other than the option R is not equipped with an earth leakage breaker. Please purchase an appropriate earth leakage breaker separately. Note 6) These values are reference values under rated conditions, and are not guaranteed. Do not use these values for the thermal set values, etc. Note 7) When a short-term interruption of the power supply (including momentary interruption) occurs in this equipment, the restarting of normal operations may require some time or may be impossible due to the operation of protective devices even after the supply of power returns.
