2. Installations and Operations
-3-
2. Installations and Operations:
Design
Caution
a. Depending on the model and operating conditions,
the oxygen ratio of the outlet air may drop below
the prescribed standard.
Do not use standard dew point -40
o
C (symbol L) type,
standard dew point -60
o
C (symbol S) type and IDG30A,
50A, 30HA, 50HA for dehumidifying breathing air. Do
not use only outlet air (dry air) in a closed room.
b. Devise a layout which considers the position of the
purge air discharge ports.
Purge air is humid air. Devise a layout in which the
humid purge air will not cause corrosion or malfunction
of peripheral equipment.
c. Time to reach the rated dew point
A certain amount of time is required to achieve the
rated dew point after the air begins flowing into the
membrane air dryer. Use the times below as a guide,
and begin operating the outlet side equipment after the
rated dew point is achieved.
Standard dew point -20
o
C, -15
o
C : about 10 min.
Standard dew point -40
o
C : about 30 min.*
Standard dew point -60
o
C : about 60 min.*
* This time can be shortened as described below.
1) Provide a valve on the outlet side of the membrane
air dryer.
2) Supply air with the valve closed so that only purge
air flows through the membrane air dryer.
3) After 15 minutes or more, open the valve and let air
flow to the outlet side equipment.
Selection
Caution
a. Consider the purge air flow rate in total flow rate
requirements.
Find the purge air flow rate from the charts and
calculate the “required outlet air flow rate + purge air
flow rate”. The air supply capacity must be at lease
equal to the calculated flow or the required outlet air
flow rate cannot be obtained.
Mounting
Caution
a. Do not obstruct the purge air discharge ports.
Dehumidification performance will decrease or may
become impossible if purge air back pressure becomes
too high or purge air stops flowing.
b. Remove water droplets from the inlet air
Water droplets in the air can lower performance and
cause malfunction.
c. Large quantities of dust (solid foreign matter) are
contained in the supply air.
When there are large quantities of dust (solid foreign
matter), install an air filter or main line filter to the inlet
side of the mist separator.
d. Ensure that intermittent pressure is not applied to
the product.
Do not frequently operate a solenoid valve on the inlet
side. The membrane dryer can be damaged if inlet
pressure is applied intermittently.

2. Installations and Operations
-4-
2. Installations and Operations:
Piping
Warning
a. Confirm locking of case and body
When using in a unit, be sure to set the air pressure to
zero before using a Mist Separator or Micro Mist
Separator with modular connections. Also, confirm that
the body and case are locked together with a click
before starting the flow of compressed air.
b. Confirm tightening of the holder.
Before starting the flow of compressed air, turn the
Membrane air dryer’s holder in its tightening direction,
confirming that it is completely tightened and that the
case will not come off.
Caution
a. Use of tools
Hold the upper portion of the body (aluminum
die-casted section) with a spanner or adjustable angle
wrench. Do not turn it while holding the case section.
b. Drain piping for separators
Use a tube of the prescribed size and keep the length
within 5 meters or less when installing drain piping for
Mist Separators or Micro Mist Separators. Be sure that
the tube does not rise up or become folded over.
c. Flush pipes before installation.
Use an air blower to flush the piping to thoroughly
remove any cutting chips, cutting oil, or debris from the
piping inside, before connecting them. If they enter the
inside of products, they could cause products to
malfunction, lower performance or damage the
element.
d. Piping materials for low dew point air
Do not use nylon tube piping and resin fittings (except
fluoropolymer) for the outlet side of the membrane air
dryer if air of a low dew point (40
o
C or less) is required,
Due to the nature of the nylon tube, it could be affected
by the ambient air, and it might not be possible to
achieve the prescribed low dew point at the end of the
tube. For low dew point air, use stainless steel or
fluoropolymer piping.
Air Supply
Caution
a. Compressed air supply capacity
An air source that has a supply capacity that is larger
than the “necessary outlet air flow rate (dry air flow
rate) + purge air flow rate” is required. See the purge
air flow rate diagram in the catalog for the purge air flow
rate.
b. Avoid chemical substances which have an adverse
effect on the product
The chemical substances stated in the table below can
reduce the performance or damage the membrane
element. Do not use the membrane dryer in an
environment containing these chemicals substances.
Type Harmful Substances
Solvent Acetone, Benzene, Phenol, Toluene,
Trichloroethylene, Xylene, Cresol, Thinner,
Aniline, Chloroform, Ethyl Alcohol, Methyl
Alcohol, Chlorobenzene, Trichloroethane,
Ethylbenzene, Isopropyl Alcohol, Dioxane,
Tetrahydrofuran, Methyl Chloride,
Cyclohexanone, Carbon Tetrachloride, Methyl
Ketone, Ethyl Ketone, etc.
Acid Sulfuric Acid, Nitric Acid, Hydrochloric Acid,
Acetic Acid, Lactic Acid, Chromic Acid, etc.
Gas Chlorine, Sulfurous Acid, Hydrogen Sulfide,
Bromine, Ozone, Ammonia, etc.
Oil Hydraulic Fluid (Phosphoric Ester), Fuel Oil,
Water Soluble Cutting Fluid (Alkaline),
Kerosene, etc.
Strong
Bases
Lithium hydroxide, Sodium hydroxide,
Potassium hydroxide, Calcium hydroxide, etc.
Others Anaerobic thread lockers
Operating Environment
Caution
a. Do not use at temperatures (fluid or ambient
temperatures) higher than the prescribed operating
conditions.
Resin is used in the membrane module (element), and
it can be damaged by operation at high temperatures.
confirm that the fluid temperature does not exceed the
membrane dryer’s range of operating conditions during
use, especially when installed immediately after a
reciprocating type air compressor.
b. Keep the inlet air temperature lower than the
ambient temperature.
Condensation and water drops may accumulate inside
of the membrane dryer’s body and reduce its
dehumidification capacity if the membrane air dryer’s
body is cooled by the ambient air.

3. Maintenance and Checks
-5-
3. Maintenance and Checks
Caution
a. Do not remove the parts and piping when the
product is pressurized. Always confirm that there is
no residual pressure present before removal of unit.
Replacement while residual pressure is present in
the product may cause injury or damage of the
product.
b. Precautions for membrane module removal
When the filter and membrane air dryer is connected by
spacer (modular connection), be sure to remove the
membrane dryer before replacement.
c. Color of the dew point indicator
The color of the dew point indicator shows the condition
of the outlet air from the membrane air dryer.
- Dew point indicator color and humidity of air
(1) Bluish ←→ Pinkish
Bluish --- Relative humidity approx. 10% or less
Pinkish --- Relative humidity approx. 50% or higher
(2) Greenish ←→ Yellowish
Greenish --- Relative humidity approx. 10% or less
Yellowish --- Relative humidity approx. 50% or higher
*1. It takes time for the color of the dew point indicator
changes.
*2. Use a dew point meter for confirming the correct dew
point.
-Discoloration other than above
Absorbent is used for the dew point indicator. The
absorbent absorbs vaporized oil or other gas
components which cannot be eliminated by micro mist
separator and the dew point indicator may turn colors
other than specified above.
In this case, it is difficult to check the humidity of the
outlet air. Please replace the dew point indicator
regularly.
It is possible to avoid discoloration by installing a super
mist separator which absorbs vaporized oil and an odor
removal filter. It is recommended to add the super mist
separator and an odor removal filter after replacing the
dew point indicator.
