
Connection to the inlet and outlet of compressed air should be made removable by using union or similar
connection.
 Support the IN/OUT ports with a wrench during tightening or loosing of fittings.
 Do not allow the equipment to support the weight of the piping.
 Isolate the vibration generated by the compressor.
o
 If the temperature of compressed air on the inlet side is higher than 122°F (50 C), place an aftercooler
unit after the air compressor.
 If the air supply makes high pressure fluctuation (pulsation), take any countermeasures such as
installing air tank.
 Clean pipes and fittings before use and select a suitable filter to prevent dust, oil or chips from entering the
air dryer, which can cause failure to the equipment.
 Use pipes and fittings that can withstand the operating pressure and temperature of the compressed air.
Make sure all connections are leak-free.
 Provide bypass piping to make it possible to do maintenance without stopping the air compressor.

2-2-4 Drain Tube

A polyurethane tube (3/8inch) O.D. is attached to the auto drain. The end of the tube is open to
atmosphere to let drain flow through the tube into a collector or drain pipe.

The compressed air is used to push out the drain periodically. Fix the outlet end of the tube in order to
prevent whipping action during discharge.

Install the drain tube in such a way so that no drain is trapped.

During installation, make sure the dryer does not sit on the drain tube which is at the bottom of the unit. Be
careful to avoid the dryer from crushing the tube during installation.

are no air leaks.

Depending on the condition of compressed air or ambient temperature, the cooling fan sometimes
alternates between start/stop at the beginning. Then, the refrigerant compressor will start and the
pointer of the evaporating temperature will indicate in the green zone. If the pointer indicates higher
than the green zone, refer to “Chapter 5 Troubleshooting.”

After running for a while, moisture will be discharging from the drain tube automatically.
Caution
・Avoid frequent On/Off operation, which may cause problems.
・The auto drain used for the equipment has a structure that closes the valve with air
pressure higher than 22psi(0.15MPa).
Therefore, until the pressure increase, air will be emitted form the drain outlet at the
begining of opening the IN side valve. Keep in mind that sometime the pressure cannot
increase enough with air compressor that has low dischage flow rate.
・Avoid using this product under the condition which has sudden pressure/flow rate
changes. Otherwise, drain (condensed water) may flow out to the secondary piping.

Compressed Air Circuit
Humid hot air entering air dryer is cooled in the cooler. At this time, the condensate is separated from the air by the
drain separator and automatically discharged. The dry air is heated by the re-heater until it gets about the same
temperature as that of ambient air. It is then discharged from air dryer outlet.
Refrigerant Circuit
The Fluorocarbon charged in the refrigerant circuit is compressed by the compressor and cooled by the condenser
to become liquid. Then, going through the capillary tube, the refrigerant pressure and temperature (evaporating
temperature) decreased rapidly. Passing through the cooler part, it draws heat from the hot compressed air and
intensely boils. Finally, it is sucked into the compressor again. The hot gas bypass valve opens to prevent
compressor from freezing when compressed air is too cold.

Air piping
Since cool air comes out from an outlet of air dryers, carefully attach thermal insulation to the piping at air
outlet and keep the piping length as short as possible in order to prevent condensation on the outlet piping
and temperature increase on the outlet due to ambient temperature.

The heat of humid hot air entering to the air drier enters to the cooler and is cooled and
dehumidified by cold fleon, separating the moisture.
The cold air is released from the air dryer.
Refrigerant Circuit
The Fluorocarbon charged in the refrigerant circuit is compressed by the compressor and
cooled by the condenser to become liquid. Then, going through the capillary tube, it is
decreased the pressure to reach a low temperature. Passing through the cooler part, it
draws heat from compressed air and intensely boils. Finally it is inhaled into the
compressor again. The capacity control valve opens to prevent dew drops from freezing
when compressed air is cooled enough.
