4. Air Supply
Warning
1. Use clean air.
Do not use compressed air that includes chemicals, synthetic oils containing organic solvents,
salinities or corrosive gases, etc., as it can cause damage or malfunction.
2. Pay attention to avoid freezing when operating the product in low temperatures.
The equipment operates while expanding the compressed air. During this time, the temperature
inside the product decreases due to adiabatic expansion. If the ambient temperature is low, using
compressed air containing a lot of moisture may cause freezing because heat cannot be gained
from the surroundings. In this case, take freeze prevention measures by using a membrane air
dryer (such as series IDG).
Caution
1. Quality of operating air
- Use air filtered by air filter AFF series or mist separator AM series, etc. Use the water separator
(AMG, etc.) when necessary. Use of a super mist separator (such as series AME) is
recommended to extend maintenance intervals.
(Equivalent to No. C to E on the page P2 to 3
of Best Pneumatics 6.
- Use of humid air may cause condensation inside the body. Use air which has been treated by a
refrigerated air dryer (such as IDF series) when condensation occurs.
-
When dew forming or freezing occur in the process pump, use the membrane air dryer (IDG)
and decrease the dew point of supply air.
- If a pump is operated by super dry air and N2 gas, etc., the deterioration of the gaskets inside
the switching valve will be accelerated and may result in substantially shortening the life span of
the product.
5. Operating environment
Warning
1. Do not use in the following environments, as this can cause failure.
1) Locations with an atmosphere of corrosive gases, organic solvents or chemical solutions, and
where there may be contact with the same.
2) Locations where there is contact with sea spray, water or steam.
3) Locations where ultraviolet deterioration or overheating of resin may occur due to direct
sunlight.
4) Locations near heat sources with poor ventilation (heat sources should be shielded by heat
insulating material).
5) Locations with impact or vibration.
6) Locations with excessive moisture and dust.
2. The product cannot be used under water.
Do not use the product immersing it in water (liquid). Otherwise, liquid will enter the openings
inside the product, resulting in malfunction.
3. Compressed air with low dew point
Using super dry air as the fluid may affect the reliability (service life) of the equipment, because
the lubrication characteristics inside the equipment will deteriorate. Please consult with SMC
when using it.
6. Maintenance
Warning
1. Perform maintenance after consulting the operation manual.
Obtain the operation manual for the equipment from SMC or our distributor and have sufficient
knowledge of the equipment before performing maintenance. Incorrect handling may cause
damage or malfunction of the equipment or system.
2. Perform maintenance work after confirming the safety of the system.
Turn off the compressed air and power supply and exhaust any remaining compressed air in the
system before removing the equipment and the compressed air supply/exhaust unit. Discharge
the residual liquid or sufficiently displace it as necessary. Also, when reinstalling the equipment or
restarting it after replacement, confirm the safety of the product before checking that it operates
normally.
