Air Supply
1. Type of fl uids
Please consult with SMC when using the product in
applications other than compressed air.
Regarding products for general fluids, please contact SMC
concerning applicable fl uids.
2. When there is a large amount of drainage
Compressed air containing a large amount of drainage can
cause malfunction of pneumatic equipment. An air dryer or
water separator should be installed upstream from fi lters.
3. Drain ushing
If condensation in the drain bowl is not emptied on a regular
basis, the bowl will overflow and allow the condensation to
enter the compressed air lines. This causes the malfunction of
pneumatic equipment.
If the drain bowl is diffi cult to check and remove, the installation
of a drain bowl with an auto drain option is recommended.
Refer to “SMC Air Preparation System” for further details on
compressed air quality.
4. Use clean air.
Do not use compressed air that contains chemicals, synthetic
oils that include organic solvents, salt, corrosive gases, etc., as
they can cause damage or malfunction.
Fittings & Tubing
Precautions 2
Be sure to read this before handling products.
Warning
Operating Environment
1. Do not use in an atmosphere where corrosive
gases, chemicals, sea water, water, or water steam
is present. Do not use in cases where there is direct
contact with any of the above.
Refer to each construction drawing on the fi ttings and tubing
material.
2. Do not expose the product to direct sunlight for an
extended period of time.
3. Do not use in a place subject to heavy vibration
and/or impact.
4. Do not mount the product in locations where it is
exposed to radiant heat.
5. Do not use the ordinary fittings and tubing in
locations where static electricity would be
problematic.
It may result in the system failure and trouble. In such places,
use of antistatic fittings (KA series) and antistatic tubing (TA
series) are recommended.
6. Do not use the ordinary fittings and tubing in
locations where spatter is generated.
Spattering may result in a fi re hazard. In such a place, use of
flame resistant fittings (KR/KRM series) and flame resistant
tubing (TRS/TRB series) are recommended.
7. Do not use in an environment where the product is
directly exposed to cutting oil, lubricant, coolant oil,
etc.
Please contact SMC if using for an environment exposed to
cutting oil, lubricant or coolant oil, etc.
8. Take note that if nylon tubing and soft nylon tubing
are used in a clean room.
The antioxidant on the surface of the soft nylon tubing may
come off, thereby lowering the cleanness level.
9. Do not use in environments where foreign matter
may stick to the product or get mixed in the
product’s interior.
This may cause leakage or disconnection of the tubing.
Warning
1. Install an air fi lter.
Install an air fi lter at the upstream side of valve.
Select an air fi lter with a fi ltration degree of 5 μm or fi ner.
2. Install an aftercooler, air dryer or water separator,
etc.
Compressed air containing a large amount of drainage can
cause the malfunction of pneumatic equipment. Therefore,
take appropriate measures to ensure air quality, such as by
providing an aftercooler, air dryer, or water separator.
3. Ensure that the fluid and ambient temperature are
within the specifi ed range.
If the fl uid temperature is 5°C or less, the moisture in the circuit
could freeze, causing damage to the seals and leading to
equipment malfunction. Therefore, take appropriate measures
to prevent freezing.
Refer to “SMC Air Preparation System” for further details on
compressed air quality.
