2-3 Environment
Warning
1. Do not use in an atmosphere containing corrosive gases, chemicals, sea water, water, water
steam, or where there is direct contact with any of these.
Refer to each construction drawing for information on the materials of air grippers.
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 shock.
4. Do not mount the product in locations where it is exposed to radiant heat.
5. Do not use in dusty locations or where water, oil, etc., splash on the equipment.
6. A decrease in the base oil of grease may be accelerated by the properties of the compressed air
used in pneumatic equipment, the external environment, operating conditions, etc., and the
resulting drop in lubricating performance may have an effect on the equipment’s service life.
Caution
1. Internal lubricant or the base oil of grease may seep out of the cylinder depending on the
operating conditions (an ambient temperature of 40°C or more, pressure retention, low-frequency
actuation, etc.). Take great care when a clean environment is required.
2-4 Air supply
Warning
1. Type of fluids
Please consult with SMC when using the product in applications other than compressed air.
2. When there is a large amount of drainage
Compressed air containing a large amount of drainage can cause the malfunction of pneumatic equipment.
An air dryer or water separator should be installed upstream from filters.
3. Drain flushing
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 difficult to check and remove, the installation of a drain bowl with an auto drain option is
recommended. For compressed air quality, refer to the SMC Best Pneumatics No. 6 catalog.
4. Use clean air.
Do not use compressed air that contains chemicals, synthetic oils that include organic solvents, salt,
corrosive gases, etc., as it can cause damage or malfunction.
Caution
1. When extremely dry air is used as the fluid, degradation of the lubrication properties inside the
equipment may occur, resulting in reduced reliability (or reduced service life) of the equipment.
Please consult with SMC.
2. Install an air filter.
Install an air filter upstream near the valve. Select an air filter with a filtration size of 5
µ
m or smaller.
3. Take measures to ensure air quality, such as by installing an aftercooler, air dryer, or water
separator.
Compressed air that contains a large amount of drainage can cause the malfunction of pneumatic
equipment, such as air grippers. Therefore, take appropriate measures to ensure air quality, such as by
providing an aftercooler, air dryer, or water separator.
4. Ensure that the fluid and ambient temperatures are within the specified range.
If the fluid temperature is 5°C or less, the moisture in the circuit could freeze, causing damage to the seals
or equipment malfunction. Therefore, take appropriate measures to prevent freezing. For compressed air
quality, refer to the SMC Best Pneumatics No. 6 catalog.
5. Precautionary measures against condensation
Moisture condensation can occur inside pneumatic systems due to a drop in temperatures caused by the
piping or operating conditions. This can degrade or wash away grease, resulting in a shortened service life
or a malfunction. For details, refer to the catalog “Precautionary measures against condensation in a
pneumatic system” (CAT.P-E01-11).
