Refrigerated Air Dryers
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
Decomposition of auto drain
caused by rusting inside pipes
Generation of water droplets
Malfunctioning of valves and
actuators caused by dripping grease

Refrigerated Air Dryers Series IDF/IDU
Compressed air contains moisture (water vapor, droplets), oil, debris and other foreign
matter. Filters and mist separators can be used to remove droplets, oil, debris, and so on,
but a dryer is necessary to remove water vapor.

∗Shows standard combinations. The suffix numbers of the model indicate port size,power supply, etc.
Refer to “How to Order” on pages 5, 9, 12, 15 and 18 for details on dryers and refer to “SMC Best Pneumatics” for other equipment.
∗The symbol “—” in the table indicates that no such equipment exists.
∗The figures for air flow capacity corresponding to air compressor output are provided for reference only.
∗The below table applies to the air pressure dew point 50°F (10°C) [at 100psi (0.7 MPa)]. In cases where other dew points are needed, refer to pages 3 and 4

The corrected air flow capacity, which considers the user’soperating conditions, is required for selecting air
dryer. Select using the following procedures.
IDF Selection Example IDU Selection Example
Read the correction
factors.
Obtain the correction factors A to
D suitable for your operating
condition from the table on the
next page.
2
Calculate the corrected
air flow capacity.
Obtain the corrected air flow
capacity from the following formula.
Corrected air flow capacity =
Air flow rate V(Correction
factor A x B x C x D)
Corrected air flow capacity = 0.3 m3/min V(0.82 x
0.96 x 1 x 0.88) = 0.43 m3/min
Corrected air flow capacity = 0.4 m3/min V(0.95 x
0.93 x 1 x 0.88) = 0.51 m3/min
4
Select the model.
Select the model with air flow capacity
which exceeds the corrected air flow
capacity from the specification table.
(For air flow capacity, refer to the data
E on page 4.)
According to the corrected air flow capacity of 0.43
m3/min, the
IDF4E will be selected which air flow
capacity is 0.52 m3/min at 50 Hz.
According to the corrected air flow capacity of 0.51
m3/min, the
IDU4E will be selected which air flow
capacity is 0.57 m3/min at 60 Hz.
5
Options Refer to pages 21 through to 25. Refer to pages 21 through to 25.
Refer to pages 5, 9 and 12.
Refer to pages 26 through to 36.
Refer to pages 15 and 18.
6
Finalize the model
number.
7
Select the optional
accessories.
8
Check the coefficient. Correction factor = 0.82 x 0.96 x 1 x 0.88 = 0.69
Max. coefficient value is 1.5 Correction factor is 1.5
when the calculation result is 1.5 or greater.
Correction factor = 0.95 x 0.93 x 1 x 0.88 = 0.78
Max. coefficient value is 1.5 Correction factor is 1.5
when the calculation result is 1.5 or greater.

JIS Symbol
Humid, hot air coming into the air dryer will be cooled down by a cooler (heat exchanger). Water condensed at this time will be removed from the air by a drain separator (auto
drain) and drained out automatically. Air separated from the water will be heated by a re-heater (heat exchanger) to obtain the dried air, which goes through to the outlet side.
Note 1) Air flowcapacity under the standard condition (ANR) [atmospheric pressure 68°F (20°C), relative humidity 65%]
Note 2) Air flow capacity converted by the compressor intake condition [atmospheric pressure 89.6°F (32°C)]
Note 3) Select the air dryer model according to “Model Selection” (page 3, 4) for models beyond the rated specifications.
Note 4) When selecting a power supply voltage, refer to “How to Order” on page 5.
Note 5) Install a circuit breaker with a sensitivity current 30 mA.

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 an
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.

High temperature humid air from the air compessor
passes through the air re-heater qand is pre-cooled
by dehumified cool air. Then, it is cooled to the
specified temperature by the air cooler wusing the
evaporation heat of refrigerant.
At this time, the oil mist and moisture generated by
condensation are automatically exhausted by the auto
drain e. The cooled and dehumidified air goes back
to the air re-heater qand heat is exchanged with hot
air that flows into the air re-heater. It is supplied as dry
warm air without “sweating” in the piping system.

Note 1) Air flow capacity under the standard condition (ANR) [atmospheric pressure 68°F (20°C), relative humidity 65%]
Note 2) Air flow capacity converted by the compressor intake condition [atmospheric pressure 89.6°F (32°C)]
Note 3) Select the air dryer model according to “Model Selection” (page 3, 4) for models beyond the rated specifications.
Note 4) When selecting a power supply voltage, refer to “How to Order” on page 15.
Note 5) For the IDU8E or larger models, cooling with the aftercooler helps save energy.
Note 6) Install a circuit breaker with a sensitivity current 30 mA.
Note 7) The part number for the auto drain components only without including the body part.
Body part replacement is not possible.

Humid, hot air coming into the air dryer will be cooled down by a heat exchanger. Water condensed at this time will be removed from the air by a drain separator and
drained out automatically. Air separated from the water will be heated by a heat exchanger to obtain the dried air, which goes through to the outlet side.
For models IDU8E to 15E, the humid and hot air introduced to the air dryer will be cooled down by the aftercooler before being cooled down by the heat exchanger.
