Design/Selection
Caution
1. Mounting the suction filter
Because the suction of vacuum equipment acts not only on
workpieces but also on dust or water droplets in the surround-
ing atmosphere, steps must be taken to prevent their penetra-
tion into the equipment’s interior.
Even when using equipment equipped with filters, if there is a
considerable amount of dust in the environment, use a
separately ordered large-size filter as well.
If there is a possibility of water droplets being sucked in by the
vacuum, use a drain separator for vacuum.
2. The maximum vacuum pressure of the
vacuum ejector is affected by the atmo-
spheric pressure of the operating environ-
ment.
As atmospheric pressure changes based on altitude, climate,
etc., the actual maximum vacuum pressure may not reach the
value listed in the specifications.
3. For information on related items, such as
directional control equipment and drive
equipment, refer to the caution sections in
each respective catalogue.
4.
Do not use the product in an environment that
exposes it to vibration. If the product is used
in such an environment, we can offer a lock
nut type product to prevent it from loosening.
Please contact SMC for model number.
Mounting
Warning
1. Operation manual
Install the products and operate them only after reading the
operation manual carefully and understanding its contents.
Also, keep the manual available whenever necessary.
2. Ensure sufficient space for maintenance
activities.
When installing the products, allow access for maintenance.
3. Tighten threads with the proper tightening
torque.
When installing the products, follow the listed torque specifica-
tions.
4. Do not obstruct the exhaust port of the ejector.
If the exhaust port is obstructed when mounted, a vacuum will
not be generated. Also, do not obstruct the exhaust port with
the goal of removing the workpiece. It may cause damage to
the equipment.
8. Check valve
SMC can issue no guarantees regarding the maintenance of
workpiece adsorption when using check valves. Take
separate safety measures to prevent workpieces from
dropping in the case of an electrical power outage, etc.
Please consult with SMC when using check valves as a
means of preventing interference caused by the exhaust from
nearby ejectors.
Vacuum Equipment
Precautions 1
Be sure to read this before handling.
Warning
1. Confirm the specifications.
Products represented in this catalogue are designed only for
use in compressed air systems (including vacuum).
Do not operate at pressures or temperatures, etc., beyond the
range of specifications, as this can cause damage or malfunc-
tion. (Refer to the specifications.)
Please contact SMC when using a fluid other than
compressed air (including vacuum).
We do not guarantee against any damage if the product is
used outside of the specification range.
2. Safe designs should be developed, which
account for the possibility of accidents
resulting from a drop in vacuum pressure
due to power failure or trouble with the air
supply, etc.
If vacuum pressure drops and there is a loss of vacuum pad
adsorption force, workpieces being carried may fall, causing
human injury or damage to machinery. Sufficient safety
measures should be implemented, such as drop prevention, to
avoid any accidents.
3. Follow vacuum specifications for vacuum
switching valves and vacuum release valves.
If non-vacuum equipment is installed in a vacuum piping,
vacuum leakage will occur. Therefore, select only equipment
for vacuum specifications.
4. Select an ejector which has a suitable suc-
tion flow rate.
<When there is vacuum leakage from the workpiece or the
piping>
If the ejector’s suction flow rate is too low, the adsorption will
be poor.
<When piping is long or the diameter is large>
The adsorption response time will delay due to the increased
volume of the piping.
Select an ejector with a suitable suction flow rate by referring
to the technical data.
5. If the suction flow rate is too high, setting of
vacuum switch will become difficult.
Setting the vacuum switch when absorbing a small (few
millimeter) workpiece will sometimes become difficult, if the
selected ejector has a high suction rate and there is a small
pressure difference when absorbing and releasing the
workpiece.
6. When two or more pads are piped to one
ejector, if one pad releases its workpiece,
the other pads will also release.
When one pad releases its workpiece, there is a drop in
vacuum pressure which causes the other pad to release its
workpiece as well.
7. Do not disassemble the product or make any
modifications, including additional machin-
ing.
It may cause human injury and/or an accident.
When disassembling or assembling the product for the
purpose of replacing parts, etc., be certain to follow the opera-
tion manual or catalogues.
