*1: ANR is the value at 20°C, atmospheric pressure and relative humidity 65%.
*2: Indicates the air flow capacity converted by the compressor intake condition (at 32°C, atmospheric pressure, relative humidity 75%).
*3: The operating range does not guarantee use at rated air flow capacity.
*4: Select the model while referring to "Model Selection" in the manufacturer's catalog.
*5: Products without option R do not come with a circuit breaker. Purchase an earth leakage breaker separately.
*6: These are characteristic values under rated conditions and are not guaranteed. Do not use these as thermal setting values, etc.
*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.

Humid, hot air coming into the air dryer is cooled down by a cooler re-heater (heat exchanger). Water condensed at this time will be drained out automatically by the auto drain. Air separated from the water is heated by a cooler re-heater (heat exchanger) to obtain the dried air, which goes through to the outlet side.
